Discussion | Deinandra fasciculata occurs in southwestern California, especially on immediate coast, and on southern Central Coast and in the western Outer South Coast Ranges. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Deinandra halliana occurs in the Inner South Coast Ranges. Evident population sizes vary greatly from year to year; active plants may be absent in dry years and form dense stands in some wet years. Madia radiata is morphologically similar to D. halliana; the two species sometimes co-occur and can be difficult to distinguish without close examination of phyllaries and cypselae.
