Discussion

In Texas, var. purpurea is known from scattered localities across the northern part of the state with a range that does not overlap with var. arenicola. Variety purpurea is introduced in Arizona and probably elsewhere.

In Texas, var. arenicola is known from the northwestern quarter of the state. Variety arenicola occurs in areas of loose sand, while var. purpurea occurs in more compacted soil. The varieties are generally fairly distinctive except in areas where the two types of soils are in close proximity.
