Oakmead Herbarium and Collections
The earliest known plant collections from the Jasper Ridge area are from 1867. Originally part of Volney Rattan's herbarium, the specimen sheets are conserved in the Preserve's herbarium and have the location Searsville. Over the intervening 145 years numerous workers have cumulatively reported more than 800 different vascular plants.
Today the Oakmead Herbarium and Collections of Jasper Ridge Biological Preserve (JROH) has over 5,400 vouchers of 794 vascular plants representing 10% of the 7,600 terminal taxa (species, subspecies, varieties) native or naturalized in California.* Specimen records are in the Consortium of California Herbaria. The herbarium also has collections of Preserve bryoflora and lichens.

* 794 minus 33 waifs and hybrids not given taxonomic status in TJM2 = 761 vascular plant taxa for JRBP and ~7,600 for California.
Photographs for most plants are linked to the Vascular Plant List entries. In addition to specimen labels and maps on many JROH specimen sheets, location, flowering time, and abundance records may also be found in the Field Observations Database and the JRBP Poales E-Flora.
