Discussion

As delimited here, var. vestitus includes populations found in habitats from moist coastal coniferous forests to chaparral, from California to southwestern Oregon. Numerous attempts to describe distinctive taxa within this series of populations (R. V. Bradshaw 1925; C. L. Hitchcock 1952; S. L. Broich 1987; D. Isely 1992) have been undermined by extensive intergradation among them.
