Discussion

Varieties 2 (2 in the flora).

Occasional plants in regions of contact between varieties of Baptisia lanceolata may be difficult to identify. D. Isely (1981) recognized isolated populations from central Florida as belonging to var. elliptica; these appear to belong to var. lanceolata, although they may be relics of ancestral hybridization and/or gene flow between the two.

Baptisia lanceolata hybridizes with B. perfoliata.
