Bambusa subaequalis H. L. Fung & C. Y. Sia

Bambusa subaequalis differs from B. indigena by its more slender culms with longer internodes, glabrous nodes, inconspicuous culm sheath auricles, and narrower leaf blades.

Culms 8–12 m, 4–6 cm in diam., basally straight, apically drooping; internodes 40–50 cm, initially thinly white powdery, glabrous; wall rather thick; nodes glabrous; branching to base. Branches 1–3 on lower nodes, nearly horizontal; branchlets on lower nodes usually specialized into weak thorns, on middle and upper nodes many, clustered. Culm sheaths deciduous, usually with 1 or 2 pale yellow-green stripes near outer margin, glabrous, apex somewhat broadly triangular or broadly arched; auricles inconspicuous, usually joined to base of blade; ligule ca. 3 mm, margin finely ciliate; blade persistent, erect, subtriangular, base nearly as wide as sheath apex, extending outward to form inconspicuous auricles, margin involute, apex sharp. Leaf blade linear, usually 9–16 × 1–1.3 cm, abaxially pilose, adaxially glabrous. Inflorescence unknown.
