Plants Seen or Cited:
UNM Specimens: New Mexico: Eddy Co., Cottonwood Spring ca 8
miles NW of Artesia. Sivinski 2605. 12/9/93.
Habitat: Canyon bottoms, moist areas around springs on
limestone, understory of cottonwood bosque; Elevation, 1300-2000 m.
Comments: Nesom (1990) stated that the most strongly perennial
forms of the taxon occur in the western extension of its range. The type specimen is
from McKittrick Canyon in the Guadalupe Mountains.
Status: The species has a limited range and occurs in sensitive
habitats. The New Mexico populations appear to represent a distinct
perennial form. It perhaps should be retained on the list for
New Mexico.
