Senacia napaulensis de Candolle, Prodr. 1: 347. 1824; Celastrus verticillatus Roxburgh (1824), not Ruiz & Pavón (1802); Pittosporum floribundum Wight & Arnott ex Royle (Jun 1834), not Wight & Arnott (Oct 1834); P. napaulense var. rawalpindiense Gowda; P. verticillatum Wallich.
Shrubs or small trees. Young branchlets brown, lenticellate. Leaves clustered at branchlet apex, biennial; petiole stout, 1–2 cm or more; leaf blade dark brown adaxially after drying, oblong or oblong-lanceolate, 8–20 × 4–8 cm, thickly leathery, glabrous abaxially, lateral veins convex adaxially, base cuneate, margin flat, reflexed afer drying, apex acute or acuminate. Inflorescences terminal, paniculate or compoundly corymbose-paniculate, usually brown pubescent; pedicels 7–10 mm. Sepals slightly connate at base, ovate, 2–3 mm, glabrous or margin ciliate. Petals narrowly oblong, 5–6 mm. Stamens ca. 4 mm. Ovary ca. 2 mm, pubescent. Style ca. 1 mm, glabrous; stigmas capitate. Capsule globose, 6–7 mm in diam., dehiscing by 2 valves; pericarp orbicular, thin, horizontally striate adaxially; placentas at base of valves. Seeds 4–8, 2–3 mm in diam; funicle very short. Fl.

Pittosporum napaulense var. rawalpindiense was described from Bhutan, N India, N Pakistan, and Sikkim, and was distinguished from var. napaulense by having leaf blades lanceolate, long acuminate at the apex, and capsules only 4-seeded. It seems to be only an extreme state of P. napaulense.
