Discussion | Subspecies 5 (1 in the flora). Coincya monensis is a variable species, within which, in spite of lack of clear discontinuities in variation patterns, E. A. Leadlay and V. H. Heywood (1990) recognized five subspecies and divided subsp. recurvata into four varieties, not recognized here. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Genera 46, species ca. 245 (13 genera, 28 species in the flora). The generic boundaries in Brassiceae are largely artificial, and the number of genera may be substantially reduced. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
