Discussion
Demaree 45724 “Wilson co, Tennessee, glades, common” (TEX, ISC) is a fruiting specimen that has graduated petioles, small leaflets, almost no stipules and long-beaked cylindrical pods that are apically tapering. Although it matches none other seen, I identified it several years ago as probably a glade form of B. australis var australis. Turner, however, annotated the plant as “B. leucanthal/ australis? (rare combination).” Mahler (1970) evidently did not see this specimen since he mapped neither Baptisia lactea nor B. australis from Wilson co. Baptisia lactea is recorded from the western third of the state, and B. australis from approximately the eastern two-thirds. Wilson co is in the range of B. australis, and I think the plant is probably this species.
