General Comments:

Based on the BONAP range map, this species is a "near endemic" -- it occurs only in the panhandle and a 3 counties in southern Alabama.

At this time, the Florida Plant Atlas shows two outlying collections.  One (Alachua County) appears to have been removed by the herbarium that "has" the specimen, the other (St. Lucie County) is a 1980 literature citation with apparently no specimen.   Neither is shown on our map.
