Discussion

Baptisia tinctoria forms hybrids with B. alba (= B. × serenae M. A. Curtis), B. lactea (B. × deamii Larisey), and B. perfoliata (B. × fulva Larisey [= B. × microphylla Nuttall]). Within Baptisia, B. tinctoria and the unifoliolate-leaved species form an isolated clade (M. G. Mendenhall 1994).
