Harry T. Cliffe Bexar Regional Herbarium

The Bexar Regional Herbarium was created by the San Antonio Chapter of the Native Plant Society of Texas in the 1990s. In support of the 1986 Texas Sesquicentennial Celebration, the chapter compiled “A Plant List for Bexar County, Texas,” from existing literature, combining lists and updating botanical names, which garnered a certificate of recognition from the governor of Texas. In the process, participants discussed verifying the presence of the listed plants by finding and identifying what actually existed in the Bexar and contiguous counties.
