Treatment appears in FNA Volume 10.

Leaves primarily cauline, rarely forming basal rosette; blade with only terminal lobe well developed, sometimes pinnately lobed, lateral lobes usually greatly reduced or absent. Flowers: floral-tube 0.5–1.3 mm; sepals 1.5–2 mm; petals 1–3 mm; anthers 0.5–0.8 mm, glabrous; style 1.5–4 mm. Capsules: pedicel 5–15 mm. 2n = 14, 28.


Phenology: Flowering Apr–Jun.
Habitat: Loose slides of limestone and other sedimentaries, sandy washes.
Elevation: 900–1800 m.

Distribution

Ariz., Colo., N.Mex., Utah.
