cymosa is a subspecies of succulent perennial plant in the family Crassulaceae endemic to California.

It is native to the California Coast Ranges, the Sierra Nevada and the Santa Monica Mountains.

This plant is commonly found growing on rocky outcrops, talus slopes, and in shaded canyons.

A solitary or few-branched rosette forming succulent with broad leaves and bright-yellow, orange, or red flowers.

The margin (edge) of the leaves is often folded upward at the widest point, and the tip of the leaf is more or less recurved and is shaped acuminate to mucronate.

[1][2] The inflorescence is typically asymmetrical radially, because the pedicels turn to the sun or away from the cliff the plant is on.

On the inflorescence are 7 to 20 bracts, positioned horizontally to ascending, and shaped ovate to triangular-lanceolate, with the tips acute to acuminate.

The terminal branches are circinate when young (spiral-shaped, like a fern frond unfurling), but are ascending in age, 1 to 17 cm long and with 2 to 10 flowers.

As there was no authentic type specimen, the neotype for the species is an illustration by John Gilbert Baker of his subsequent combination, Cotyledon cymosa, in William Saunder's Refugio Botanicum.
