Discussion | Varieties 2 (2 in the flora). Varieties candida and oligophylla were treated as separate species by D. K. Wemple (1970) and are fairly well defined. In regions of overlap, var. oligophylla normally occupies higher, drier sites than var. candida. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
