Adinandra angustifolia (S. H. Chun ex H. G. Ye) B. M. Bartholomew & T. L. Ming

The stamens in three whorls and a simple style place this species in Adinandra rather than in Cleyera. However, the seeds of the two genera are quite different and need to be examined when appropriate material becomes available.

Shrubs. Branchlets slender; terminal buds glabrous. Petiole 3–8 mm, glabrous; leaf blade narrowly lanceolate, 3.5–7.5 × 0.4–0.7 cm, both surfaces glabrous, midvein elevated on both surfaces, secondary veins 6–9 on each side of midvein, base narrowly cuneate, margin entire and revolute, apex acuminate and with a black mucro. Flowers solitary. Pedicel 2.4–2.7 cm; bracteoles 2, ovate, ca. 2 mm. Sepals ovate, 3–4 × 2–3 mm, margin ciliate, apex obtuse. Petals white, obovate-oblong, 9–19 × 5–7 mm, apex acute. Stamens ca. 25, in 3 whorls, 6–7 mm; filaments 4–5 mm; anthers ca. 2 mm, with filiform trichomes, apex mucronate. Ovary ovoid-globose, glabrous; style ca. 5.5 mm, simple, glabrous. Fruit and seeds unknown. Fl. Apr.
