Sepals conspicuously 3-veined, 3.5–4.5 mm, apex acute.

Discussion

M. F. Baad (1969) noted that var. subcongesta may be a xerophytic form of var. simulans. B. Maguire (1960) noted the existence of two historical records of var. subcongesta from Arizona, neither of which indicates a specific locality; we have not seen material from that state.
