by Wright (no. 1314).

New Mexico: Organ Mountains. Canyons, in the Upper Sonoran Zone. 
The species is known to us in New Mexico only from the Organ Mountains, where 
it is a common spring plant growing among the rocks. It should occur in the moun- 
tains of the southwestern corner of the State, and probably does, but no collector has 
been there at the proper time of the year to find it.
