Discussion | Species 7 or 8 (3 in the flora). Following the example of J. G. Baker (1879) and R. R. Gates (1918), this treatment of Tofieldia excludes the species of sect. Triantha, which is recognized instead as a distinct genus; see J. G. Packer (1993). Tofieldia sometimes has been treated very broadly, to include not only Triantha but also Pleea (W. B. Zomlefer 1997c). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
