Leafl. Bot. Observ. Crit. 2: 149. 1911.

Common names: Sierra pussytoes
Endemic
Synonyms: Antennaria alpina var. scabra (Greene) Jepson Antennaria media subsp. ciliata E. E. Nelson Antennaria media subsp. pulchella (Greene) Chmielewski Antennaria scabra
Treatment appears in FNA Volume 19. Treatment on page 410. Mentioned on page 390, 395, 406, 409, 411, 415.

Dioecious. Plants (1–) 3–12 cm (stems usually stipitate-glandular). Stolons 1–4 (–9) cm. Basal leaves 1-nerved, spatulate to linear-cuneate, 6–12 × 1.5–4.5 mm, tips mucronate, faces glabrescent-scabrous to gray-pubescent (often with purple glandular-hairs). Cauline leaves linear, 3–11 (–13) mm, usually not flagged (apices acute to acuminate), rarely distal flagged. Heads 4–6 in corymbiform arrays. Involucres: staminate 4–5 mm; pistillate 3.5–4.5 mm. Phyllaries (relatively wide) distally dark brown-black (sometimes light-brown or whitish at very tips; apices blunt). Corollas: staminate 1.9–2.8 mm; pistillate 2–3 mm. Cypselae 0.7–1.3 mm, glabrous or slightly papillate; pappi: staminate 2.5–3.5 mm; pistillate 2.5–3.5 mm. 2n = 28 (as A. media).


Phenology: Flowering summer.
Habitat: Moist subalpine-alpine meadows, snow basins, margins of tarns, streams, or run-off from snow masses
Elevation: 2800–3700 m

Discussion

Antennaria pulchella is the diploid progenitor of A. media and, consequently, a progenitor of the A. alpina complex (R. J. Bayer 1990d). The A. rosea and A. parvifolia complexes also have the genome of A. pulchella, shown in the high elevation clones with dark phyllaries in these two polyploid complexes. Antennaria pulchella is differentiated from A. media by shorter pistillate or staminate corollas and shorter cauline leaves (Bayer). This sexually reproducing diploid ranges from the area around Lake Tahoe to the Mt. Whitney region (Bayer).
