Stems (0.6–) 0.8–2.2 (–2.8) dm. Basal leaves: petiole differentiated from blade, (0.6–) 0.9–2.2 (–3.3) times longer than blade; blade ovate to oblong, (3.5–) 6–16 (–20) mm wide, base cuneate. Cauline leaves (4–) 7–16 (–21). Racemes often compact. Fruiting pedicels horizontal or slightly descending, forming an angle 80º or more with rachis. Flowers: petals pinkish purple or, occasionally, white, (6–) 6.5–11 (–13) × (1.5–) 2–4 (–5) mm. Fruits often winged, obovate to obcordate, 7–12 (–16) × (4–) 4.5–6 (–9) mm, 1–2 times as long as wide, apex truncate to emarginate; style (1.8–) 2.5–3.5 (–4.2) mm. Seeds 4–6 per fruit. 2n = 14.


Phenology: Flowering Mar–Jun.
Habitat: Shady areas on slopes, in canyons and gulches, igneous rocky ravines, steep banks, woods
Elevation: 1300-2100 m

Discussion

R. C. Rollins (1966, 1993) recorded a tetraploid count of 2n = 28 from Hinsdale County, Colorado, but subsp. fendleri does not occur in that state, and his count is based on plants of subsp. glauca.
