Baptisia calycosa
Varieties 2 (2 in the flora).
Baptisia lactea forms hybrids with B. lanceolata, B. nuttalliana, B. sphaerocarpa (B. × sulphurea Engelmann), and B. tinctoria (B. × deamii Larisey).
Peripheral intergradation between var. lactea and var. pendula occurs (hence their treatment as varieties); they are not known to co-occur at present.
