Rose, J. N. 1895. Contr. U.S. Natl. Herb. 1 : 305.
Type Status:
Syntype
Place:
Colima, Mexico, North America - Neotropics
Collection Date:
9 Jan 1891 to 6 Feb 1891
Notes:
One of two original sheets at US (USNH 208939, 208940), neither one clearly the holotype. Note also that protologue cites another collection, Donnell Smith 1939. Fryxell (1988, 1992) cites "holotype" at US but does not effectively lectotypify.
