Species Distribution Maps
Chromosome Number(s)x = 7 Additional NotesCinna is a genus of four species, all of which generally grow in damp woods, along streams, and in wet meadows. One species, Cinna latifolia, is northern temperate and circumboreal. The other three species are restricted to the Western Hemisphere. Cinna poaeformis (Kunth) Scribn. & Merr. extends from Mexico to Venezuela and Bolivia.
