Culms ca. 8 m, to 5 cm in diam.; internodes green, 40–50 cm, glaucous below nodes, glabrous; nodes not raised, remains of sheath base persistent. Culm sheaths green, brown spotted or not, base subglabrous, margins brown ciliate, apex broad and concave; auricles elliptic; oral setae present; ligule arched, sometimes truncate or slightly concave; blade erect, striate, narrowly lanceolate to linear-lanceolate, ca. 1/4 as wide as sheath apex, glabrous, base slightly constricted, apex acuminate. Leaves 4–6 per ultimate branch; sheath densely pubescent, soon caducous, margins densely ciliolate; auricle circular to elliptic, very small; oral setae soon caducous, straight or curved, rigid; ligule acute, to 8 mm; blade oblong-lanceolate or narrowly lanceolate, 12.5–22 × 3–2.4 cm, abaxially pubescent with denser hairs along midrib, secondary veins 5–7-paired, base cuneate, margins sharply serrulate, apex acute. Inflorescence unknown.

Pseudosasa longiligula is not to be confused with P. longiligulata (McClure) Koidzumi, a much smaller species currently placed in Sasa. This species might be better included within P. maculifera.

The edible shoots are sweet, and the culms are used for making small items of furniture and props.
