In our November 2019 newsletter we discussed the Los Osos Habitat Conservation Plan, a plan prepared by the County of San Luis Obispo to address the impacts of development in Los Osos. In that plan there is a great deal of discussion of the Morro manzanita, Arctostaphylos morroensis, a plant that is listed by the U.S. Fish and Wildlife Service (USFWS) as Threatened under the authority of the federal Endangered Species Act. It is also a list 1B species, indicating rarity in California and elsewhere. What may not be as well known is that Morro manzanita is also the dominant vascular plant species of a rare natural community known as Morro manzanita chaparral, the Arctostaphylos morroensis Shrubland Alliance, as deﬁned by the Manual of California Vegetation (Sawyer, Keeler-Wolf and Evens, 2009). This is an example of a natural community that is dominated by a listed species. Not all sensitive natural communities are.
Morro manzanita chaparral has a global ranking of G1 and a State ranking of S1, which is the highest (and rarest) ranking a natural community can have. Remember the Giant coreopsis scrub that we reviewed in our last newsletter? That community was G3, S3, also sensitive, but not as sensitive as the Morro manzanita chaparral, at least according to the California Department of Fish and Wildlife (CDFW) VegCAMP program. The Program and the CNPS Vegetation Program review the rankings, which are based on the NatureServe’s Heritage Methodology.
Morro manzanita chaparral occurs in three primary areas in the Los Osos/Montana de Oro area. It occurs north of town in the Elﬁn forest and northeast of the Middle School; south of town on the north-facing slopes above Highland and Rodman Drive; and in two large stands in Montana de Oro State Park. The Plant Communities committee of the SLO Chapter has sampled each of these areas using the Rapid Assessment techniques of the VegCAMP program, and we have found that in the 4 stands sampled, the cover of Morro manzanita varies from 23 to 85 percent, with the average being 53 percent. Other species occurring in these stands include chamise, wedge-leaved Ceanothus (Ceanothus cuneatus), and coast live oak. There are many other species, such as monkeyﬂower, black sage, and phlox-leaved bedstraw (Galium andrewsii), but they occur at very low cover values. The stands are almost impenetrable due to the low shrubby branches of the manzanita, and if it weren’t for already created trails in some of these areas, it would be difﬁcult to walk through them. Two stands we sampled are located on north slopes; one on a south slope, and another on a fairly ﬂat surface. On the Geologic Map of the San Luis Obispo-San Simeon Region (1979), all are shown to be on dune sands, but there are outcroppings of soft shales in the Cabrillo Heights area.
Many interesting mushrooms, bryophytes, and lichens occur in this community.
One of my favorite lichens is the pixie-cup lichen (Cladonia sp., see photo), which can be found on the moist soils alongside the trails beneath and sometimes on the lower bark of the Morro manzanitas. There are several species in the area. One very rare species, Cladonia ﬁrma, occurs primarily in the coastal sage community just north of the Morro manzanita chaparral in the Morro Dunes Ecological Preserve, but it also ﬁlters into the chaparral in some areas where the two communities intermix as a mosaic. A unique mushroom I found two years ago in the stand south of Highland Drive is the coral mushroom (Ramaria sp., see photo). I almost felt as if I was underwater when I saw it! It was growing under the manzanita in colonies with other mushrooms.
Also occurring within this community is the Indian Knob mountainbalm (Eriodictyon altissimum), a species that is listed by the USFWS and the CDFW as Endangered. It is also a 1B species. This species occurs in only a few other areas in San Luis Obispo County, at Indian Knob near San Luis Obispo, and in Hazard Canyon at Montana de Oro. It appears to establish clones from rhizomes, and, like the Morro manzanita chaparral, is ﬁre-dependent.
Morro manzanita chaparral is a very rare natural community that is seriously threatened. It’s location near Los Osos provides a unique habitat for contemplation, exercise, and enjoying nature. However, in some areas, it is being loved too much. Individual plants are being trimmed haphazardly by unofﬁcial trail makers. Erosion of the very sandy soils is sometimes severe, creating extensive scars, exacerbated by foot and horse trafﬁc. The issue of ﬁre clearance to keep the public safe needs to be studied and addressed if it proves to be detrimental. And, although some populations are preserved, as always, we need to be ever vigilant of development being proposed within the area.

Bonnie’s drawing for this issue of OBISPOENSIS has never been used in any local newsletter. Bonnie drew it for Dr. David Keil and my plant taxonomy text back in the early 1970’s. Why has it not been used? Well, first a look at Bonnie’s drawing will indicate that the species produces inconspicuous flowers. It lacks petals, and the flowers are semi-hidden in the axils of its somewhat succulent leaves, and the species is not native to California. Its common names include New Zealand, or dune, spinach, Tetragonia tetragonoides. For you old timers like me, back in the 1970’s its most common published scientific name was Tetragonia expansa.
New Zealand spinach is considered by many to be an invasive weed. I assume we must go along with that, but my experience with it around here is that it’s not particularly good at it. It prefers slightly salty (halophilic) soils. It also seems to require a bit of disturbance. So, look for it at the upper, less salty edge of salt marsh and/or on coastal benches, especially in disturbed sites where few other species can grow. A few individual plants have been found along the edge of Los Osos Creek, west of Bay View bridge. It is especially common along the trails south of Spooner’s Cove in Montaña de Oro State Park, where it became sufficiently dense to warrant a targeted removal project. It can also be encountered as a weed all along the coast.
New Zealand spinach belongs to a family of flowering plants, Aizoaceae, that is primarily native to the Southern Hemisphere. New Zealand spinach is, in fact native to Southern Africa but has spread to New Zealand and is apparently a serious weed throughout southern Australia. Obviously, it has also been introduced into North America and Eurasia. The genus, Tetragonia, has around a dozen species and its generic name is derived from the four (tetra-) wings that are produced on the green fruit. These wings dry up and essentially disappear in the mature fruit. The inconspicuous flower displays a pale yellow color, but the flowers have no petals, only sepals as it only produces a single whorl of perianth (collective term for sepals and petals). If a perianth has only one whorl, botanists tend to regard them as sepals. These sepals, as well as the stamens are attached to the top of the ovary which makes the ovary inferior. The more famous and probably even more weedy members of the Aizoaceae are the ice plants
(Carpobrotus and Mesembryanthemum).
Wherever New Zealand spinach is found growing, its leaves have been used as a green vegetable. One web source indicated that the Magellan expedition around the world was especially happy to find a patch of it. They would pick the leaves, boil them and then dry (preserve) them for eating. It was particularly good in preventing scurvy! However, note that they boiled the leaves before eating them. The leaves contain enough oxalate chemicals to cause oxalate poisoning. Oxalate chemicals are usually destroyed by boiling.

About the Artwork: The plant on the cover of this issue of the Obispoensis is the elegant clarkia or mountain garland (Clarkia unguiculata). It’s another drawing by Mardi Niles, using Prismacolor Verithin color pencils. When I first saw Mardi’s work, they were a fantastic study of the development of an inflorescence and the opening of flowers. I remember them as pencil sketches. Later, I saw them as beautiful finished watercolors. Unfortunately, our mailed chapter newsletter often has a grey-scale print on the cover.
Now let’s talk about elegant clarkia. It gets that name because its flowers are beautiful (and elegant) and the plant stands tall (up to 3 feet or more) which adds to its elegance. As can be seen, the 4 petals have an unusual shape. They have a long, narrow base and a broad triangular tip. Botanists call this shape ‘spatulate’. The sepals are fused into a disk that’s attached below the attachment of the 8 stamens. Note that only four of the stamens look like normal, functioning stamens with large anthers and the other four have tiny anthers. I don’t know if they have any function or not. Note the single flower bud shown in the picture. It is deflexed or has its tip pointing downward. This is an important character used to separate groups of species in the genus, Clarkia.

Elegant clarkia is endemic to California where it ranges throughout the foothills of the Coast and Sierra Nevada ranges. It seems to be rare or absent away from hills. The distribution map for the species in California resembles a big ‘O’ with the Central Valley inside the ‘O’. I find that the easiest place to find elegant clarkia growing is on roadsides, especially roadsides passing through hilly country. It is especially noticeable growing with thistle sage at Shell Creek.
Dr. Keil’s SLO County Flora (in preparation) will be recognizing a close relative of the Clarkia ungiculata, C. tembloriensis. C. tembloriensis, as its name implies was probably described from plants growing in Temblor Range. Dr. Robert F. Hoover, in the original San Luis Obispo County Flora, has a relatively long discussion of the two species that ends in his concluding that the two species intergrade so much in eastern San Luis Obispo County that it would not be productive to try and separate them. Well, we’ll have to wait to read what Dr. Keil has to say about them when his new County Flora is available.
Elegant clarkia makes a wonderful addition to a native plant garden; especially in a flower bed set aside for annuals. I first became acquainted with the plant in Ralph Baker’s Shell Beach front yard Ralph was the acting Chapter President when I joined the Chapter back in 1970. It was Ralph’s clarkias that inspired me to see if it would grow for me despite my very brown thumb. Since it is said to grow readily from seed, I obtained my first seed at a Chapter Plant Sale many years ago. Today, it now grows luxuriantly in my front yard in San Luis Obispo adobe clay despite most of my horticultural sources recommending well drained soils. Seed from my adobe grown plants were at the SEED EXCHANGE set up before our October Meeting and will also be available at the upcoming PLANT SALE the first Saturday in November.

Heather Johnson has a new watercolor for us to use on the cover of this issue of Obispoensis. One might ask what is the origin of the practice of putting a different plant on the cover of each Obispoensis issue? It all started with the founder of our CNPS chapter, Dr. Robert Hoover. At the beginning of the first CNPS chapter meeting I ever attended (Fall, 1969) Dr. Hoover got up and made a presentation of what he called the “Plant of the Month.” It turned out the plant he chose to discuss was not a native plant or to even be known to exist in the wild. He discussed Franklinia alatamaha or Franklin Tree, a plant that had been collected and described from Georgia during Colonial times but after exhaustive searches hadn’t been found since. Why did he talk about a plant extinct in the wild? It had just appeared on a newly published United States postage stamp!
However, Heather’s cover watercolor is of a plant found throughout California as well as all the surrounding states. One or more of its varieties spread north into British Columbia and South all the way to Central America. The plant is seen on practically every spring field trip, but I’m reluctant to call it common. I prefer to think of it as widespread. Miner’s lettuce prefers shaded, moist, disturbed areas. It tends to be common during the rainy season and spotty other times. In the early spring, when there’s still lots of surface water, it can be found just about anywhere. I have a picture from the Shell Creek area of it growing in the crotch of a blue oak tree.
I also suspect everyone who has any experience with native plants, especially edible native plants, already knew what it is. Yes, it’s most commonly identified around the central coast as miner’s lettuce (Claytonia (Montia) perfoliata). In a book entitled Edible Wild Plants (originally, 1939) by Oliver P. Medsger, that has been in my library since my childhood, has also been called Indian lettuce, or Spanish lettuce and in Europe it’s cultivated under the name of winter purslane. All these names refer to use as a spring green. I suspect the name, miner’s lettuce, is the most recent and probably dates back only to the mid-1800s when California was over-run with miners looking for gold. I also am sure the miner’s diet was mostly tubers, grain, legumes with some meat and whisky. All of these ‘foods’ lacked enough required vitamins and minerals which would have been amply supplied by grabbing a handful of miner’s lettuce leaves on the way to a stream to pan for gold.
Heather’s watercolor is only of a couple of flowering stems which produce the leaves that were used to coin the second part of the scientific name – perfoliata. The situation where a leaf blade base appears to be passed through (perforated) by its stem is said to be perfoliate. The regular leaves are all basal and form a mound a few inches high and wide. Each basal leaf is modestly succulent and is in the shape of the spatula from your kitchen. It has a long tapering base and broad squarish or egg-shaped tip. I suspect it’s these basal leaves that were eaten.
You may also have noticed that there are two possible generic names for this plant – Claytonia and Montia. So, which is the correct genus? Also, if you go to older floras and wildflower books you will find that its botanical family seems to have changed from Portulaccaceae to Montiaceae. The name currently valid according the Jepson Manual, 2nd Ed. Is Claytonia perfoliata and is placed in the Montiaceae family. According to the Jepson Manual, the change in genus and family is referenced to a paper published in 2006. This means that the change is probably based on modern DNA sequence data as well as new technical descriptive data which was then organized using current computer classification techniques. The Jepson Manual also noted that some of the characters used required a microscope with 20X magnification which most of us don’t have. This procedure resulted in miner’s lettuce (along with a couple of other species) being moved from the genus, Montia, to the genus Claytonia which included several species of spring beauties. The remaining species in Montia remained in Montia and a new family was created for them – Montiaceae. Why didn’t the species name (perfoliata) change when the species was moved to a new genus? This is due to another rule of Botanical Nomenclature. When a species is moved from one genus to another, the species epithet moves with it unless the species epithet already exists in the new genus. If it does, the mover must come up with a new name for the species in its new location. Since the epithet, perfoliata, didn’t already exist in Claytonia, the epithet moved with miner’s lettuce’s scientific name to its new location. This rule helps keep track of name changes.

The illustration on the cover of this Obispoensis is another of Heather Johnson’s wonderful watercolors. It was just too beautiful not to use, in spite of the fact its natural range barely reaches our Chapter’s area.
The text below was written by Alice Meyer back in the 1970’s or early 80’s for the local Audubon Chapter Newsletter. Alice, along with her husband, Bud, were the very first recipients of the Chapter’s Hoover Award. As you will probably gather from Alice’s discussion below, she was a very good native plant gardener. She is also the person most directly responsible for the creation of our annual plant sale back in the early 1970’s.
I feel compelled to add one additional tidbit about the Matilija poppy. It had a very important but behind-the-scenes role in a 1998 film entitled “The Mask of Zorro.” The plot of the movie involved the kidnapping of a young girl, who was then taken back to Spain where she grew up and where she was told she had been born. Upon returning to California, she remembered the odor of the plant her true parents had placed around her crib. That plant, of course, was the Matilija poppy which as you are about to learn is basically confined to California (Upper and Lower). But, let’s leave it to Alice to tell you the rest.
The Matilija poppy is regarded as one of our most magnificent perennial wild flowers, with its gray-green foliage and its 3-5 inch wide crinkly white flowers. It was discovered by Dr. Thomas Coulter, who named it after the Britsh astronomer Dr. Romney Robinson. Hence the botanical name, Romneya coulteri Rom-nee-a colt-er-i).
The common name, Matilija poppy, was bestowed because it grew so profusely in Matilija Canyon in Ventura County, but it is also found in canyons and washes from Santa Barbara to lower California at 1000-2500 feet. Locally one may see it occasionally along the roadside on Hwy 101 from San Luis Obispo to Arroyo Grande. It flowers from June to September. This plant is so attractive it is much in demand for home gardens, but nurseries have the plant for sale only occasionally.
Growing it from seed is difficult, since the seeds are very slow germinating – (up to 2 years). Germination can be hastened by planting in sand in a flat with a foot of pine needles on top, then burning the pine needles. When cool, remove the ashes and water the flat from the bottom. When the seedlings have a few true leaves, transplant into small containers. When containers are full of roots, transplant the plants in gallon cans.
Propagation may also be done from root cuttings taken in December or January, which is the easiest way to propagate the plant. After the plants are set out, they should receive supplemental water for the first two years, but when well established, natural rainfall should suffice.
Our Chapter almost always has it at our annual native plant sale in November. From conversations overheard at our plant sale Matilija poppy is relatively difficult to get started. Customers indicate that they have tried several years before having success, then they complain that once established, the species can be difficult to contain).
The native plant on the cover of this Obispoensis is a beautiful rendition of a species of the genus Calochortus. The painting is another of Heather Johnson’s. If you’re seeing it on the mailed version it will be in shades of gray. You can see the painting in the original spectacular color if you go to the Chapter website (cnpsslo.org). Heather identified the painting only as ‘mariposa’ and I’m not going to try to identify it to species. It often requires characters that are not present in the art work such as whether the fruit is pointed up or down. Besides, it’s the genus that’s discussed below.
Calochortus is a large genus (70 species) spread over the western third of the United States. The genus’ range extends north into Western Canada and south into Central America. That said, California has nearly half (27) of the species. Many of the California species are endemic, such as our own Chapter flower, the Obispo star tulip (Calochortus obispoensis). If you note that the species name (obispoensis) is the same as the name of our newsletter, it’s not a coincidence. Alice Meyer (our very first Hoover Award Winner) thought the species name of our endemic star tulip (found on local serpentine, i.e. Cuesta Ridge) was indicative of our Chapter area.
Calochortus is a genus in the lily family (Liliaceae). This large family of monocots is generally easy to recognize by its large showy flowers that often consists of three large showy petals and three usually colored sepals that often can be as large and as showy as the petals. Think lilies and/or tulips. However, that is not the case in this genus as their sepals are small. Like a lot of monocots Calochortus has 6 stamens and a single pistil that matures into a capsule. The genus takes these basic elements and produces at least three very distinctive flower shapes, which, in our area match the three common names most associated with this genus.
A 1998 evolutionary study (T.B. Patterson) of the genus determined that there were 4 evolutionary lines within the genus. Two of these lines correspond closely to two of the common names. These are mariposa lilies and fairy lanterns. In the fairy lanterns orglobe lilies, the flowers are nodding and the broad petals come together at their tips to form a hollow globe-like structure. Petal colors are usually subdued and lacking in conspicuous spotting. Fairy lanterns tend to be found in oak woodlands or closed woodlands.
In contrast, the mariposa lilies produce upright flowers with the petal tips spread apart so as to form a cup. The individual petals are usually ornamented with conspicuous markings. The markings make obvious a large, colored (nectary?) gland that usually occupies the base of each petal. This flower form is very widespread and I’ve seen it in the Sierras and the Great Basin. Flowers are usually arranged as seen in Heather’s painting. Obviously, Heather’s painting is of a species that would belong to this group.
Star-tulips make up the third flower form. This group usually produces less showy flowers with petals that are triangular in shape and of darker colors. In addition, the petal color is often difficult to see due it being hidden by the tufts of trichomes (hairs) that cover the upper surface. The petals are flat and all in the same plain. The flowers are usually orientated vertically so the petals resemble a 3-pointed star. Our Obispo star-tulip belongs to this group. Star tulips are often found in Chaparral or mountain woodlands. For the record, there is some confusion in my mind in the application of the common names –star-tulip and the cat’s ear mariposas.
The last evolutionary line is titled the cats ear mariposas. I’m not familiar with this name and when I tried to google it I got lots of remedies for curing problems with real cats ears. However, the species I know that were said to belong to this group had the mariposa lily flower configuration. The web noted that cat’s ear mariposas are associated with wet lands.
According to the web many of the Calochortus species were used by Native Americans for food (especially their bulbs), medicine and ceremony. One source noted that the bulbs were eaten by the Mormon settlers between 1853 and 1858 when famine threatened the new immigrants to the Great Salt Lake Valley, due to crop failures. I suspect many of the species in this genus would make excellent additions to any native plant garden, especially one that lies dormant and un-watered throughout the summer drought. The problem would be getting material to plant as few nurseries keep them in stock.
This is a repeat plant from 1997. At that time, the article was accompanied by a grainy black and white photograph. This time the article is accompanied by a beautiful painting by Los Osos resident and CNPS member, Heather Johnson, who has given permission for us to use it in the Obispoensis. Keep on reading!
The cover of this Obispoensis is another beautiful water color by Heather Johnson. When I chose this beautiful and accurate representation, I expected that I could just go to my archive and update an article I had already written. To my surprise, Bonnie hadn’t drawn and I hadn’t written anything about it. I’m going to use the excuse that Hummingbird sage is so distinctive and so common that we took it for granted that everyone already knew it. It was one of the first California wildflowers I learned after I arrived in California from the Midwest. In our area Hummingbird sage can grow in an extensive mat. Its leaves are large (10 in (20 cm) long and 3 in (8 cm) wide). The leaf surface appears quilted. Its family affiliation (Mint or Lamiaceae or Labitae) is shown clearly in Heather’s water color. Its large red, two-lipped tubular flowers appear in our area by March and last well into summer and are borne in tight clusters; the clusters climbing upward resembling the balconies of an oriental pagoda. The two stamens and single style extend from under the upper lip in succession. The stamens appear first and after all the pollen has been removed they are replaced by the stigma at the end the style. Mint family characters also shown are the opposite leaves and the square stem. Unfortunately, the characteristic mint odor characteristic of this family is fruity (I smell lemon), but either way it’s not discernible in Heather’s art.
I’ve found three common names for this mint. They are crimson sage, hummingbird sage, and pitcher sage. The first two names are readily explainable. The usual flower color is dark red (crimson) and red is the color of flower that hummingbirds frequently visit. The name, pitcher sage, requires a little history. When I came to California in the late 1960s, the only wildflower books readily available were authored by the Southern California botanist, Phillip Munz, and emphasized Southern California common names. In those books Salvia spathacea was given the common name ‘pitcher sage’. So, we botanical oldsters probably remember it by that name. However I remember that hummingbird sage was always the name used on field trips in our area even then and the name, ‘pitcher sage’ was used for a completely different shrubby mint, Lepechina calycina, which grows in the interior mountains of our chapter area.
Based on my observations and the numerous accounts on the web, hummingbird sage has a place in a California Native plant garden, especially gardens away from the coast. It prefers partial shade, but where it doesn’t get too hot it can tolerate sun. It even does well under oaks. It even prefers clay soils rather than sand. For areas that have many deer, they seem to avoid eating it. Its large flowers with lots of nectar make it great for attracting and feeding hummingbirds. I suspect the best situation in which to plant them would be an area that is visible, but little trod upon. Here it can even become a sort of ground cover. I found no real references for its use in medicine other than for ailments in which its wonderful odor might be helpful. According to the book on Chumash Ethnobotany, the Cumash didn’t have a name for it although the early Spanish settlers did. Some suggested it might make a decent tea. No member of the genus, Salvia, was in any of the indices of books on poisonous plants I have in my library.
I’m introducing a new artist with this cover of the Obispoensis. The artist is Heather Johnson, who paints beautiful renditions of California native plants, so I asked her if she would allow them to be displayed on the Obispoensis cover. Thankfully, she agreed and has sent me several. I was really taken by the first one I looked at! It was of a leafy twig of the California grape in fall color. California grapes are widespread through Northern California where they favor, but are not restricted to, stream sides. However, I was surprised by Heather showing them having bright red color. If you are seeing the cover in black and white, I recommend that you go to cnpsslo.org and see them in their brilliant red color. The leaf color rendition produced by Heather closely matches the color of the leaves I saw in photos on the Web.
There is a problem with the leaf color however, and trying to resolve it lead me to a very interesting story. This is because the usual fall color of California grape leaves is pale yellow not red. So where did the red come from. It turns out that the entire story of its finding and selection is well known and is worth a google search. In late October 1983, Roger Raiche of the U.C. Berkeley Botanic Garden, first saw a California grape with bright red leaves growing alongside Palmer Creek Road in rural Sonoma County, west of Healdsburg, California. He collected cuttings, rooted them in the green house and finally planted them out in the botanic garden. They grew easily and with minimal care and little water. Later he gave cuttings to a garden volunteer who was also a member of the local California Native Plant Society Chapter. She donated a flat of them to her CNPS Chapter’s plant sale. She labeled the flat simply “Roger’s red grape.” When those plants were sold, the name was born, although the cultivar ‘Roger’s Red’ has never been registered or patented.
So far we find we have a cultivar with very unique fall color that was found growing wild. But, we still haven’t discovered the origin or the red color. It turns out careful observation of the cultivar ‘Rogers Red’ indicated that it’s not pure Vitis californica and that it shared characteristics with the European wine grape (Vitis vinifera). Further observations limited the possible ancestor to a particular variety of commercial vine grape commonly grown for its reddish fruits. The red fruits of this variety were used to add extra color to red wines. This variety was and still is Vitis vinifera ‘Alicante Bouschet’ and has been grown in California for years. As well as reddish fruits, this variety of wine grape produces bright red leaves in the fall. Enter DNA to the story. Several DNA studies proved that the cultivar ‘Roger’s Red’ is truly a hybrid between the native California grape and the European wine grape Vitis vinifera var. Alicante Bouschet.
This California native (hybrid) is extremely popular and is widely available at nurseries and probably CNPS native plant sales around the state. It’s easy to grow and tolerates many different soils, watering regimes and different levels of shade. Its major fault might be its rapid, aggressive growth. It will require taming. Its fruits are edible, but the seeds are large and the flesh is thin. Not a great ‘eat-off-the vine’ fruit but they can be turned into a nice drink.
I chose the Pismo clarkia because it grows in the area surrounding Mardi’s home and nowhere else. It grows naturally in about 20 occurrences from the southern Edna Valley, south through the foothills and valleys of the Southern San Luis Range, ending east of Pismo Beach and Arroyo Grande (Huasna Valley).
