Calif.

Discussion

Variety pycnostachyus occurs along the immediate coastline of central and northwestern California in Marin and San Mateo counties and is apparently disjunct in central Humboldt County.

R. C. Barneby (1964) noted of var. pycnostachyus that he had not observed any convincing example of a natural legume fall or dehiscence of this late-flowering, tardily maturing, small-podded taxon.
