Description
Species Description - Xylopodial shrub or tiny tree 0.6-1.5 m tall, the branchlets subterete, usually densely pubescent, without apparent lenticels. Leaves bipinnate, 6-20(-30) cm long, with 8-12(-16) pinnae, each pinna with villous rachis (sometimes slightly winged) and 6-16(-20) sessile, very narrowly oblong-elliptic to narrowly oblong ovate leaflets, these 15-20(-25) cm long and 3-5(-8) cm wide, apex acutish, the base rounded or minutely cordate, entire, pubescent with rather long erect trichomes, usually more or less densely so below (the surface thus macroscopically somewhat grayish), coriaceous, strongly bullate. Inflorescence a panicle, puberulous, with bracts sublinear, leaflet-like, to 20 mm long. Flowers with the calyx cupular, shallowly 5-dentate, 5-10 mm long, 4-7 mm wide, more or less hirsute; corolla deep purple, tubular-campanulate above a narrow basal tube, 3.5-4(-4.5) cm long, to 2 cm wide at the mouth, the lobes 0.5-0.7 cm long, the tube 3-3.5 cm long, rather sparsely puberulous outside with both simple and subsessile gland-tipped trichomes, glabrous inside except for a few gland-tipped trichomes at the stamen insertion; stamens didynamous, the anthers bithecate, each theca 2 mm long, the long staminode ca. 3-3.5 cm long, subexserted, slightly capitate, glandular villous only near apex, otherwise rather sparsely pubescent with short gland-tipped trichomes; ovary flattened-ovate, slightly contracted at base, 1.5 mm long, 1 mm wide, glabrous; disk subconical-pulvinate, 1 mm long, 1.5 mm wide. Fruit round to elliptic, apically rounded with a thickened ring-like basal stipe, rather woody, 3.5-5.5 cm long, 3-4 cm wide (l:w = 1-1.6), the margin not undulate at dehiscence, glabrous and very sparsely lepidote, drying brown to blackish; seeds small-bodied with a surrounding suborbicular wing, 8-14 mm long, 14-24 mm wide, the wing hyaline-membranaceous with a narrow brownish base, clearly demarcated from the seed body.

Discussion
Very distinctive in its narrow bullate pubescent leaflets; its only close relative is J. pulcherrima (see discussion under that species). The Ule specimen at Hamburg is a more appropriate lectotype than Claussen 119 (G), proposed by Morawetz, since it matches the protologue equally well and the species was named for Ule.
