Vascular Plants of the Harry D. Thiers Herbarium at San Francisco State University (SFSU)

The Harry D. Thiers Herbarium at San Francisco State University maintains over 113,000 specimens. Its primary research focus is mycological, but there are roughly 10,000 vascular plant specimens. Most vascular plant specimens were collected from approximately the 1990s to 2010s by Bob Patterson, V. Thomas Parker, and their students. Special vascular plant collections of SFSU include the California Polemoniaceae, an robust collection of most Arctostaphylos (Ericaceae) taxa, and a current collection focus on taxonomically diverse genera of the California Floristic Province such as Ceanothus (Rhamnaceae) and Eriogonum (Polygonaceae). The vascular plant collection is curated by Jason T. Cantley.
