Discussion
Marah fabacea var. fabacea was mapped by K. M. Stocking (1955b) as confined to near-coastal localities centering around San Francisco Bay, from Marin to Monterey counties; he recognized var. agrestis as the more widely distributed expression of the species. In his view, var. fabacea is characterized by fruits with longer (6–12 mm) and rigid spinules and by seeds more numerous (usually four) and commonly laterally flattened. R. A. Schlising (1993) noted that var. agrestis intergrades more or less completely with plants identifiable as var. fabacea and did not recognize varieties.
