Discussion

Baptisia hirsuta is known from the western Florida panhandle; within its range, it can be locally abundant and can invade secondary sites (D. Isely 1998). It differs from B. calycosa by its geography and vestiture. M. M. Larisey (1940) maintained B. hirsuta; Isely (1981, 1998) treated it as a variety of B. calycosa. M. G. Mendenhall (1994), using DNA data, treated these two taxa as species, noting that they formed a tight clade with B. lecontei.
