Discussion
Canavalia rosea is frequent in Dixie County and central and southern peninsular Florida (R. P. Wunderlin and B. F. Hansen 2011), as well as being found in south coastal Texas in Cameron and Kenedy counties. D. Isely (1990) reported Canavalia rosea also from Alabama and Mississippi; corresponding specimens from those localities were not seen.
