Zephyranthes candida
Zephyranthes refugiensis
W. Herbert (1837) suggested that Zephyranthes candida might belong in a segregate genus, and within ten years Rafinesque and M. Roemer each separated it from Zephyranthes. Its leaves are about twice as thick as those of other species in the genus, and they persist through winter frosts and snow, a rare, if not unique, characteristic in Zephyranthes. The stigmatic lobes are not globose, as in Z. chlorosolen, but are somewhat erect and might be described as very abbreviated linear lobes; a careful study of fresh stigmas of “capitate” species is in order. Also, the chromosome complement of Z. candida appears to be anomalous within Zephyranthes. The species has been maintained in Zephyranthes for more than a century, but were Herbert, Rafinesque, and Roemer correct after all?

Of conservation concern.
Morphology, cytology, and distribution suggest that Zephyranthes refugiensis arose as a hybrid between Z. pulchella and Z. jonesii. It is known only from Goliad and Refugio counties.
