Type Status:
Isolectotype
Place:
Guaymas. [Protologue, "Madagascar"], Sonora, Mexico, North America
Collection Date:
1887
Notes:
Protologue cites type as Scott Elliot s.n. from Madagascar, apparently due to a labeling error. See Notul. Syst. (Paris) 13:163-166 (1948). "Scott Elliott s.n." = Palmer 217 according to annotation by B. MacBryde (1970).
