Bole is up to 60 cm in diameter, fluted. Bark is dark pale grey-brown and smooth when young, turning grey-black and rough at the base when aging. Branches are thickish, marked with small white lenticels. Leaves are usually opposite (rarely 3 at a node), odd-pinnate, up to 50 cm long, confined to tips of branches, with about 4-7 pairs of leaflets. Leaflets are broadly elliptic or ovate, entire, sessile or with a very short petiolule, dark green and slightly glossy above and lighter green beneath, apex slightly acuminate, base somewhat asymmetrically obtuse, veins prominent beneath. Petiole is up to 6-15 cm long, thickened at base. Rachis is brownish. Inflorescence is 8-10 cm long terminal raceme on a peduncle of about the same length. Pedicels are up to 6 cm long, longer in lower part of inflorescence than in upper part. Pedicels are thick, brownish, subtended by early falling 1 cm long bracts. Flowers are bisexual, zygomorphic, about 10 x 5-7 cm. Calyx is spathaceous, 4-8 cm, long-acuminate, splitting down on one side. Corolla is widely campanulate, 5-lobed, orange-red with yellow margin and throat, or yellow throughout. Stamens are 4, in two pairs of unequal length inserted on corolla tube. Style is slender, stigma is 2-lamellate. Fruit is a narrow, hard, woody follicle, up to 27 cm long, dehiscing by one longitudinal suture, many seeded. Seeds are thin, flat, ca. 1.5 cm × 2 cm, with a 1 cm broad transparent wing.
