Its leaves are linear to lance-shaped, 1.5–4 mm (0.059–0.157 in) long and 0.5–0.75 mm (0.020–0.030 in) wide on a petiole 0.1–0.3 mm (0.0039–0.0118 in) long, with stipules up to 0.25 mm (0.0098 in) long at the base of the petiole. The flowers are on a peduncle 0.2–0.5 mm (0.0079–0.0197 in) long, the floral tube is more or less spindle-shaped or cylindrical, 3.0–3.5 mm (0.12–0.14 in) long and has ten ribs.
