Discussion | Erythronium multiscapideum is unusual among western species (and resembles some eastern species) in its tendency to reproduce vegetatively through the production of bulbels at the ends of stolons. It is similar in many respects to E. californicum and sometimes intergrades with it, resulting in occasional populations with the bulb characteristics of one species and the inflorescence branching pattern of the other.

Of conservation concern. Erythronium pluriflorum is known only from Madera County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
