Branches many, clustered, central 3 dominant. Culm sheaths deciduous, leathery, rigid, apex slightly asymmetrical, arched or shallowly undulate, abaxially with yellow-white stripes, both sides sparsely stiffly dull brown strigose, sparser to nearly absent abaxially, denser adaxially, sheaths on basal 2 nodes densely hairy on lower half; auricles unequal, minutely wrinkled, margin sparsely thickly shortly setose near ends, larger ones oblong or nearly oblanceolate, ca. 1.5 × 0.5–0.7 cm, smaller usually continuous with blade base, oblong-oblanceolate if separated from blade, 1/3–1/2 size of larger one; ligule 1–1.5 mm, shortly dentate, very shortly fringed; blade erect, asymmetrically ovate to narrowly ovate-triangular, those on lower nodes usually with yellow-white stripes, base slightly rounded and joined to auricles for 4–5 mm, ca. 5/7 width of sheath apex, apex acuminate, apiculate. Leaf blade linear, 7–15(–24) × 0.9–1.5(–2.2) cm, abaxially pilose, adaxially scabrous. Pseudospikelets usually in clusters of 3–5 at nodes of flowering branches, linear-lanceolate, 2–2.5 × 0.4–0.5 cm; prophylls ca. 3 mm, 2-keeled, keels ciliolate; gemmiferous bracts subovate, ca. 4.5 mm, glabrous, 15-veined, apex obtuse and mucronate; florets 5–7, apical one sterile; rachilla segments flat, ca. 3 mm, glabrous, margin erose, apex enlarged. Glumes 1, oval, ca. 5 mm, 15–17-veined, glabrous, apex obtuse and mucronate; lemma elliptic, 7–9 mm, glabrous, 17–19-veined, apex obtuse, mucronate; palea linear-lanceolate, 7.5–9.5 mm, keels glabrous, 8-veined between and 2-veined on either side of keels, margin very shortly ciliolate, bifid with apices of keels extended and deflexed, apex subtruncate; lodicules 3, unequal; anterior 2 oblique, ca. 3 mm, margins long ciliate; posterior 1 nearly obovate-elliptic, ca. 2 mm. Anthers ca. 4 mm. Ovary broadly ovoid, ca. 1 mm, base stalked, apex thickened and hispidulous; style very short, 0.4–0.5 mm, hispidulous; stigmas 3, ca. 6 mm. Mature caryopsis unknown.

The nomen novum Bambusa albolineata was published in the belief that the original epithet "albostriata" was blocked by the earlier but not validly published nomen nudum "B. albostriata Hort. ex Lavalleé" (Arbor. Segrez. 306. 1877). Nevertheless, B. albolineata is legitimate because of the change in rank.
