Hexalectris orchids are uncommon to extremely rare species of mycoheterotrophic orchids found in limited and potentially endangered ecological areas. 

In 2004, several Texas Master Naturalists from the North Texas Chapter began assisting a University of Dallas biology professor, Dr. Marcy Brown-Marsden, in her summer field work observing, counting and measuring these special plants.  The data collected over these 20 years has created a body of knowledge where very little was known about them before this effort. 

This presentation will explain the geology that underlies their limited habitat. It will detail the five species (out of the 6 found in Texas) that we have observed and collected data on plus explain the field work project. 

It has been an excellent partnership between a scientist and Texas Master Naturalists that could expand to other Texas Master Naturalist chapters and other botanists to further enhance the science.
