Discussion

Of conservation concern.

Limnanthes vinculans is the only member of the genus in which the first few leaves produced by the seedling are entire rather than lobed. It is known only from Sonoma and Napa counties, where it occurs in the centers of vernal pools. Some populations are sympatric with L. douglasii subsp. nivea, which tends to grow on the drier edges of vernal pools. Limnanthes vinculans is in the Center for Plant Conservation’s National Collection of Endangered Plants.
