Discussion
Of conservation concern.
R. C. Rollins (1939c, 1993) treated plants of var. texana under both var. integrifolia and var. pinnata. As shown by Turner, var. texana is somewhat distinct morphologically and is disjunct by ca. 800 km from the nearest populations of var. pinnata. Also, it grows on gypseous instead of seleniferous soils. It is found only in Brewster County.
