| Character Abstract | |
|---|---|
| Identification Comments: | Within its habitat, it may be identified at all times of year by its combination of oval to reniform, abruptly stalked leaves, and unbranched flowering stems.<br /><br />Plants 1–5 dm wide; leaf blades broadly elliptic to oval or reniform, 0.3–0.7 cm usually white-tomentose, the margins almost never not brownish; scapes erect, (1) 5–15 (18) cm long, tomentose; inflorescences capitate, 1–2 cm wide, the branches absent; involucres 3–10 per cluster, 4–5 mm long; flowers 4–5 mm long, the perianth white. |
| Subspecies Comments: | 1 Leaf blades 0.2–1.2 (2) cm long; scapes usually 0.3–5 (9) cm long, rarely longer; involucres usual |
| Lookalikes: | |
| Phenology Comments: | Usually in bloom from late May through late June. |
| Reproduction Comments: | Seed viability <1%, reproduces from seed and possibly by vegetative splitting. |
| Habitat Comments: | Young, shallow, poorly-developed, dry soils derived from siliceous opaline sinter precipitated by past thermal spring flows, but not currently near surface water, in open areas with sparse Atriplex confertifolia, Sarcobatus vermiculatus, Chrysothamnus nauseosus, etc. Sometimes found on adjacent deeper and/or disturbed soils when competitive vegetation is lacking. |
| Ecology Comments: | |
| Inventory Comments: | Inventory and mapping essentially complete. |
