Discussion | Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 3 or more (2 in the flora). Several entities (segregate species, subspecies, varieties, and forms) have been described within the Chenopodium glaucum group. Most of the taxa represent morphological traits of individual or ecological variability and have little or no taxonomic importance. However, several entities are well delimited geographically. The native North American taxon is recognized here as a separate variety. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
