Discussion | Morphological similarities between Lathyrus splendens and L. vestitus var. alefeldii (R. V. Bradshaw 1925; C. L. Hitchcock 1952) are such that these two taxa might be considered a parent-offspring species pair worthy of an evolutionary study of factors involved in their origin. Lathyrus splendens is known from the South Coast and Peninsular Ranges. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Lathyrus sylvestris is similar to L. latifolius and intermediate populations are known to occur in Europe (M. Valero 1991). In North America, L. sylvestris is distinguished by its distinctly narrower stipules. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
