Habit | Plants solitary or tufted, with bulbils on caudices. | Plants in groups or, sometimes, almost mat-forming, rhizomatous. |
Leaves | ± basal; petiole absent; blade linear to narrowly elliptic, 0.5–4 cm, fleshy, base cuneate, margins subentire, ciliate, surfaces hirsute. |
basal; petiole flattened, 5–7.5 cm; blade ovate to elliptic, 3–4 cm, fleshy, base attenuate, margins shallowly crenate-serrate, sparsely ciliate, surfaces tangled, reddish brown-hairy. |
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.) Flowers: sepals reflexed, elliptic; petals white, each with 2 basal yellow spots, triangular to broadly ovate, clawed, 3–5 mm, longer than sepals; filaments linear, flattened; pistils connate 1/2+ their lengths; ovary superior, (to 1/3 adnate to hypanthium). |
(10–)30+-flowered, open, lax, strongly divaricately branched, conic thyrses, 8–30 cm, purple-tipped stipitate-glandular; (bracts glabrous, proximal marginally ciliate). |
Flowers | sepals ascending, ovate to oblong, (margins eciliate, surfaces glabrous); petals white, not spotted, obovate to ± round, clawed, ca. 2 mm, ca. 1.5 times as long as sepals; filaments linear, flattened; pistils distinct almost to base; ovary nearly 1/3 inferior, (to 1/3 adnate to hypanthium). |
|
Capsules | green to yellow, purple tinged, valvate. |
greenish to reddish purple, folliclelike. |
2n | = 20, 38, 40. |

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.
