Leaves scattered; lamina ovate or elliptic, (7-)10-25 by (3-)5-14 cm, cuneate to truncate at the base to a petiole 5-10 mm long, mostly obtuse or rounded or sometimes acute at the apex, dull on both sides; venation pinnate with the midrib and the somewhat curvinerved main laterals distinct above and prominent and raised below. Inflorescences at the nodes, a 10-to 20-flower-ed raceme; axis 10-20(-40) mm long; pedicels 0.5-1 mm long. Corolla in mature bud 5-merous, (18-)22-26(-30) mm long, slender, weakly clavate and acute at the apex, mostly cream or yellow or green below and red above; tube in the open flower 14—20 mm long with the lobes reflexed 2-4 mm higher, slightly curved. Anther 1-1.5 mm long, acute, half to one fourth as long as the free part of the filament.
