From Flora of Indiana (1940) by Charles C. Deam
Usually frequent in moist woods throughout the state. Our two species seem to intergrade and some authors regard the next one [A. bracteata var. comosa] as only a race or vigorous form of this species. Schively expresses this doubt when she says the var. comosa is "an extremely vigorous" form of this species (Contr. Bot. Lab. Univ. Pa. 1: 356. 1897). Besides the winter pods, this species has subterranean 1-seeded pods, autumnal 1-seeded pods, and pods, which are usually 3-seeded, from petaliferous flowers. [Amphicarpaea bracteata var. comosa, if recognized, is] infrequent to frequent in moist woods throughout the state and sometimes in prairies. This species much resembles the preceding [Amphicarpaea bracteata] but, besides the characters given in the key to distinguish it, the plant is larger and coarser, and the leaflets especially are thicker and larger.
