Resumen:
Exposures of Yeso Formation gypsum along the western escarpment (The Rim) of the Guadalupe Mountains in southeastern New Mexico were first explored botanically in 1996, which revealed the existence of two gypsophilic taxa, Anulocaulis leiosolenus var. howardii and Mentzelia humilis var. guadalupensis, both of which are only known from that area. Fieldwork by the authors has revealed another gypsophile restricted to The Rim, Nerisyrenia hypercorax, which is here described. The new species is similar to N. gypsophila and N. mexicana, from which it differs in having shorter, crispate fruits and smaller floral parts. We also report a new state record of Paronychia wilkinsonii in New Mexico and make additional observations regarding the gypsum flora of The Rim. © 2014, Botanical Research Institute of Texas Inc.
