Of conservation concern.

Limnanthes bakeri is known from the Inner Coast Ranges of Mendocino County. It is easily recognized by having relatively few leaves with broad, mostly entire leaflets. The stamens and styles are about equal in length and are pressed together by a funnel-shaped corolla, facilitating self-pollination (R. V. Kesseli and S. K. Jain 1984b). Combined ITS, trnL, and morphological analyses placed L. bakeri in a basal position with respect to the Limnanthes (as sect. Reflexae) clade, and most closely allied with L. vinculans (M. S. Plotkin 1998). W. H. Parker and B. A. Bohm (1979) suggested that Floerkea proserpinacoides and L. bakeri separated from the family line long before the separation of other species.
