Discussion | Of conservation concern. Phemeranthus sediformis is poorly known and merits further study in the field and better representation in herbaria. When its characters and their ranges of variation are better known, it may prove to be indistinct from P. spinescens. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
