Caudices simple or 2–5-branched, 1–2(–3.5) cm diam. Leaves: rosettes usually 10–25-leaved; blade green, rhombic-oblanceolate to spatulate, 1.5–5(–10) × 1–3(–6) cm, apex mostly short-acuminate to cuspidate, surfaces sometimes farinose, glaucous. Inflorescences: floral shoots 5–20-leaved, 5–15(–25) cm; cincinni 3+, 3–6-flowered, mostly 1–3 cm. Petals bright yellow to red, 10–12 × 2.5–4 mm. 2n = 34.
Phenology: Flowering spring.
Habitat: Rock crevices, rocky slopes
Elevation: 100-2600 m
Discussion
Plants of subsp. pumila in the San Gabriel Mountains are rather uniformly small, with the rosette leaves rhomboid and short-acuminate to cuspidate. Taken by themselves, they would seem a quite well-distinguished subspecies, and many plants of the Santa Lucia Mountains are similar. Plants of the San Bernardino Mountains are similar but apparently more variable; in the Santa Lucia Mountains the plants are perhaps even more variable, some like subsp. cymosa. Thus there is no clear line between the two subspecies.
