Ivesia lycopodioides var. lycopodioides

Treatment appears in FNA Volume 9. Treatment on page 232.

Stems decumbent to ascending, 0.3–1 (–1.5) dm. Basal leaves 1–7 cm; leaflets tightly overlapping, glabrous or sparsely short-hirsute, lobes ± orbiculate, ± 1 mm, apical setae 0 (–0.5) mm. Cauline leaves 0–1. Inflorescences usually ± capitate, 3–15 (–20) -flowered, 0.5–1.5 (–2) cm diam. Flowers 6–9 mm diam.; petals obovate, 2–3 × 1 mm; filaments 0.8–1.2 mm; styles 1–2 mm. 2n = 28.


Phenology: Flowering summer.
Habitat: Dry rocky flats or slopes, fellfields, in high-elevation sagebrush communities, subalpine to alpine conifer woodlands, alpine tundra
Elevation: 3000–4000 m

Discussion

Variety lycopodioides occurs in the Sierra Nevada from El Dorado and Alpine to Fresno counties, and on the Sweetwater Mountains of Mono County, California. The voucher reported by D. D. Keck (1938) from the Carson Range of Washoe County, Nevada, has not been located for confirmation. Of the three varieties, var. lycopodioides tends to have plants with the smallest leaflet lobes (ca. 1 mm) which lack apical setae. Plants also have more consistently simple caudices bearing a single rosette of glabrous or sparsely hairy leaves atop an enlarged, fleshy taproot.
