Discussion | Specimens of Zephyranthes drummondii with rare biflowered inflorescences were collected by B. C. Tharp in 1939 and 1946 in Austin, Texas. The species has naturalized in Florida. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Morphology, cytology, and distribution suggest that Zephyranthes smallii (predominantly 2n = 54) arose from hybridization between Z. pulchella (2n = 48) and Z. chlorosolen (2n = 60 in Cameron County) in Brownsville. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
