Habit | Plants solitary or tufted, with bulbils on caudices. | Plants solitary or in groups, with bulbils on caudices. |
Leaves | ± basal; petiole absent; blade linear to narrowly elliptic, 0.5–4 cm, fleshy, base cuneate, margins subentire, ciliate, surfaces hirsute. |
basal; petiole flattened, 0.5–2.5 cm; blade ovate to elliptic, 1–2 cm, ± fleshy, base attenuate, margins sharply serrate, sparsely to densely ciliate (some glandular-tipped), surfaces densely tangled, reddish brown-hairy abaxially, glabrous adaxially. |
Inflorescences | usually 2–3+-flowered, open, lax thyrses, sometimes solitary flowers, (flowers terminal, proximal usually replaced by bulbils, sometimes bulbils absent), 2–25 cm, stipitate-glandular. (Pedicels reflexed.)

Discussion | Specimens of Micranthes bryophora from the disjunct populations in Idaho have been called Saxifraga bryophora var. tobiasiae; they appear to overlap in morphology with the California plants and are not distinguished here.
