Good News!

In view of the Covid-19 pandemic, GNPS experimented with a Zoom meeting on Friday, April 17th. One of our favorite researchers, Russ Kleinman, gave a presentation on lichens (see below). All those who participated were enthusiastic, so we decided to hold meetings via Zoom at 7:00 pm on third Friday evenings in May and June. Dr. Edwin Leuck agreed to give us a two-part presentation on cacti. 

Dr. Leuck, now a resident of Silver City, is emeritus Professor of Biology at Centenary College of Louisiana in Shreveport, LA. He taught courses in botany, plant systematics, ecology, conservation biology, microbiology and introductory biology from 1980 to 2016. His interest in cacti is of long standing: While studying for his M.S. and Ph.D. degrees at the University of Oklahoma, he researched and presented scientific papers on the distribution of the Oklahoma cacti and their propagation. His doctoral dissertation dealt with the systematics of the small-flowered hedgehog cacti in the genus Echinocereus, a project that entailed extensive field work in the Texas Big Bend region as well as the prairies and mountains of west Texas and areas of New Mexico and Colorado east of the Continental Divide. He continues to look for cacti in New Mexico, especially in the Bootheel and southern Gila regions, and is currently involved in a long-term study of a Peniocereus greggii (Arizona Queen of the Night) population near Rodeo, New Mexico.

On May 15th he discussed the family of Cactaceae in general. See below.




Coryphantha vivipara

June 19, 2020 – Virtual Meeting. “The Cacti of New Mexico”

His June presentation will include most of the native cacti present in New Mexico, their distributions, habitat specificities, salient (hopefully diagnostic) characteristics, and lots of photos.  Included will be 13 genera and 40+ species.

The way Zoom works is that you get an email invitation with the link to the meeting (and directions). When the time comes closer we will be sending an invitation to all Gila Native Plant Society members who have favored us with their emails. Anyone else who is interested may email us at and request an invitation.

Save the date!





Past Meetings:

May 15, 2020 – Virtual Meeting. “The Cactaceae. Diversity of Form, Function, and Habitat”

In his presentation in May, Ed Leuck presented the characteristics that make a cactus a cactus. These include bits of internal anatomy, external morphology, and some  physiology. He discussed the major groups of cacti and the diversity contained within, and the economic importance of some members of the family.

Friday, April 17, 2020 Meeting via Zoom. “Lichens for Beginners”, Presenter Russ Kleinman

Caloplaca approximata

One of our favorite researchers, Russ Kleinman, gave  a basic introduction to lichens – what they are, how they have been used, their biology and some of the most common lichens in our area.

The presentation was much appreciated, and the Zoom experiment was a success.
