How many of you have photographed a manzanita in the field, or brought back a leaf, and then had trouble identifying it using a key? There are many manzanitas in the County, and a lot share common features. You ask yourself if what you have matches what is described in the key. One helpful tool is to use something like the CalFlora web site to see what other people thought as a match to the species name, but those photos may not flag key diagnostic features from the key. Don’t you wish you had a bunch of correctly identified specimens lying in front of you for comparison? Well… you can…. At the CCH2 web site you can enter and examine specimens from dozens of herbaria.
On the opening page, select ‘image search’ and then type in the latin binomial into the search page. You can also search by common name, family, or taxonomic group. Click Load Images to see thumbnails of all herbaria sheets matching your search criteria. Select a thumbnail, and another page will open with data on the sample. Open Large Image will open a high resolution picture of the specimen. Once loaded, your cursor will turn into the ‘+’ which allows extreme close up.
This is sufficiently detailed to enable you to see glands on stem hairs, and details of leaf surfaces, and you will have a lot of samples for most species. Those of you who attended the workshop before the last meeting were learning how to enter data from herbarium sheets, and this site is where a lot of the data will reside.
