W. A. Weber

Sida 20: 511, fig. 1. 2002.

Treatment appears in FNA Volume 20. Treatment on page 551. Mentioned on page 546.

Perennials, 5–20 cm (caudices branched). Herbage glabrous. Stems usually single. Leaves progressively reduced distally (basal and proximal withering before flowering); petiolate (petioles purplish, weakly winged, 4–5 cm); blades broadly-triangular-ovate to suborbiculate, 2–4 (–5) × 2.5–3 cm, bases truncate to ± cuneate, margins coarsely spinulose-dentate (mid leaves similar, persistent). Heads nodding, 4–6. Calyculi of “few,” linear bractlets. Phyllaries ± 13, 7–9 mm, tips green. Ray-florets “few”; corolla laminae ca. 7 mm (inconspicuous, equaling or barely surpassing phyllaries). Cypselae glabrous.


Phenology: Flowering Aug.
Habitat: Alpine rock ledges
Elevation: 2500 m

Discussion

Of conservation concern.

Senecio spribillei (from Snowshoe Peak, Cabinet Mountains) is similar in aspect to S. neowebsteri of the Olympic Mountains, Washington.
