Leaves bipinnate, 20-45 cm long, with 13-21 pinnae, the pinnae 5-11 cm long, the leaflets 7-27 per pinna, sessile, elliptic or oblong, obtuse, at base cuneate or rounded, (7-)10-20(-22) mm long, 5-8 mm wide, the margin entire or with a few teeth, revolute, drying dark above, tan below, the nerves conspicuously impressed above, somewhat raised below, puberulous above, tomentose below. Inflorescence a large dense panicle, the branches puberulous-pilose, the lower bracts bipinnate, the bracteoles lanceolate. Flowers with the calyx cupular or suburceolate, 8-10 mm long, 5-6 mm wide, irregularly 5-dentate, densely gray-puberulous; corolla violet with white throat, tubular campanulate, (4.5-)5-6.5(-7) cm long, 3-4 cm wide at mouth, the lobes 0.8-1 cm long, puberulous or glandular-pilose outside and on lobes; stamens dithecate, the staminode to 4.5 cm long, club-shaped, the apex bifurcate or emarginate, glandular-villose; ovary glabrous; disk annular-pulvinate.

Discussion
Most closely related to J. ulei but differs in being a small tree to 4 m high rather than a xylopodial shrub only 1 m tall, in larger leaves with more pairs of pinnae, the divided staminode apex, and thinner fruit.
