A tree (Johnston). Stems or branches of the specimens seen herbaceous or sub-woody, 1 1/2–2 lin. thick, terete, glabrous. Leaves alternate, thin, 2 1/2–6 in. long, 3/4–2 in. broad, lanceolate, acute or acuminate and apiculate at the apex, tapering from above or below the middle into a petiole 1/4– 1/2 in. long, glabrous on both sides. Stipules none. Umbel terminal or with the branch ultimately developing beyond it, composed of 3–6 rays 2–5 in. long, once or twice forked, glabrous. Bracts 2 1/2–6 in. long, 1 3/4–5 lin. broad, elliptic or elliptic-ovate to suborbicular, obtuse or rounded at the apex and base, apiculate, glabrous on both sides. Involucres on very short peduncles, solitary in the forks or at the ends of the ray-branches of the umbel, about 2 1/2 lin. in diam., cup-shaped, glabrous, with 4 glands and 5 subquadrate-ovate lobes, minutely 2-toothed at the apex and ciliate; glands 3/4–1 lin. in their greater diam., transversely oblong, half-circular, or subrectangular, with 2 teeth or short horns, sometimes reduced to minute points at the outer angles. Capsule 3–3 1/2 lin. in diam., glabrous, exserted on a long recurved pedicel; styles about 3/4 lin. long, very shortly united at the base, rather deeply bifid at the apex, suberect. Seeds 1 3/4 lin. long, subglobose-ellipsoid, tuberculate.
