Plant Systematics

The Plant Systematics program at UTPA investigates a variety of plant groups in distant reaches of the world. One prominent component of my research program investigates species diversity and adaptive radiation in New World morning glories (Convolvulaceae). These activities complement floristic research on plant communities that inhabit limestone substrates in northern Mexico, Laos, and Cambodia, with an eventual aim to elucidate the biogeographic relationships between disjunct plant groups of tropical North American and Southeast Asia. The Plant Systematics laboratory and Herbarium (PAUH) also supports students that are interested in the natural history of the Rio Grande ‘Valley’ flora, with emphasis on rare and endangered species.


Following studies made in the field of archaeo-ethnobotany, we continue to explore lotus imagery in mythic and artistic traditions of the New and Old World. These investigations now include the study agricultural practices in prehistoric Indo-Aryan societies, with a focus on the domestication and dissemination of barley (Hordeum) and the eastern lotus (Nelumbo).
