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


Phenology: Flowering late spring–summer.
Habitat: Open, rocky, sagebrush slopes and flats, volcanic soils
Elevation: 1300-2800 m

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.
