Herbage densely hairy. Stems erect to ascending. Flowers cupshaped; sepals accrescent, obovate, 7.5–10 mm, abaxially and adaxially densely hairy; petals broadly obovate-cuneate, 8–10 mm, apex truncate or slightly emarginate; filaments 3–7 mm; anthers 1–1.5 mm, usually dehiscing extrorsely; style 3.5–4 mm. Nutlets 3–5, tubercles broad-based, platelike cones.


Phenology: Flowering Mar–Apr.

Discussion

Of conservation concern.

Subspecies californica occurs in Butte County on the eastern edge of the Sacramento Valley and on Table Mountain. It is sympatric with Limnanthes alba subsp. alba; it flowers earlier. J. A. Dole and M. Sun (1992) found no evidence of hybridization between them.
