San Antonio Chapter

The Harry T. Cliffe Bexar Regional Herbarium: The Second Pioneer Project of NPSOT-SA

**ARCHIVED POST ** from 2019-05-29

June 25, 2019 Chapter Meeting:

In the early 1990s, NPSOT San Antonio members determined to verify the presence of plant species they found named in a variety of historic plant surveys of our region. Thus began a disciplined process of collecting, documenting, and pressing plants of the region after members received professional-quality training and were given exceptional guidance by their beloved guide, Harry Cliffe. This collection of almost 1,200 specimens is now being housed at the Witte Museum, and its images can be found on the Ladybird Johnson Wildflower Center’s online Native Plant Database whenever you look up a plant that was found by them here. This effort created a cadre of knowledgeable contributors to the education of the public in our region, with a couple of them still contributing what they can. Come hear the stories of this wonderful project and how it went from orphan collection to being adopted, photographed and made available to the whole world. And you will also find out what the first NPSOT-SA pioneer project was.

Melissa Miller is past president of the San Antonio Chapter and state, and is co-founder of the Native Landscape Certification Program. Lottie Milsaps is one of the creators of the collection who has taught countless people on the trails of Bexar County and currently maintains the berm created by our chapter at Friedrich Natural Area. Helen Holdsworth is the Vice President of Public Programs at the Witte Museum.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
