Discussion | Lithophragma parviflorum is easily identified throughout its range, although morphological variation is apparent when comparing specimens from different habitats and elevations in western North America. Some authors treat L. trifoliatum as a variety of L. parviflorum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Lithophragma cymbalaria is the only species of the genus with a single pair of opposite cauline leaves. It shows a high degree of self-compatibility, with abundant seeds produced; it may produce abundant bulbils. It is found from Stanislaus County to Santa Barbara County including the northern Channel Islands. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
