The ASU Herbarium is the largest component of the Angelo State Natural History Collections (ASNHC) and comprises about 80,000 plant specimens that are pressed, dried and mounted on archival paper and filed in metal cabinets. It is the eighth-largest herbarium in Texas and represents the most complete floristic inventory of the Concho Valley of Texas.
In addition to this special emphasis, the Herbarium serves as a permanent depository for voucher specimens for floristic surveys of several unique areas in West Texas, including Big Bend National Park, Texas Nature Conservancy Big Brushy Canyon and Texas Nature Conservancy Independence Creek.
Specimens resulting from several ecological and systematic studies of rare plants are also housed in our collection. We have significant holdings in the Poaceae and Cyperaceae. Our official abbreviation is SAT.
The Herbarium employs undergraduate assistants and welcomes volunteer help.
