From Flora of Indiana (1940) by Charles C. Deam I collected this species in a second growth wooded ravine May 19, 1918. There were several vines supported by low trees and shrubs about 10 feet high. My specimen has pubescent branches and branchlets; 4 leaves, 15-23 cm long, all with 9 leaflets; leaflets slightly pubescent on both sides, more or less acuminate; inflorescence 21 cm long; pedicels about 10 mm long, glandular; calyx tube glandular, about 4 mm long, the longest lobes about 2 mm long; spur of wings of corolla about as long as the claw; pod glabrous. …… Indiana Coefficient of Conservatism: C = 4 Wetland Indicator Status: FACW
