Dendrobium brachypus

Dendrobium brachypus is an epiphytic or lithophytic orchid with crowded, yellowish green pseudobulbs 5–50 mm (0.2–2 in) long and 4–8 mm (0.2–0.3 in) wide. Each pseudobulb has between two and four dark green, egg-shaped to elliptic leaves 7–20 mm (0.3–0.8 in) long and 4–10 mm (0.2–0.4 in) wide. The flowering stems are 10–25 mm (0.4–1 in) long and bear two or three cream-coloured to whitish or greenish flowers with thick ovaries. The flowers are 5–7 mm (0.2–0.3 in) long and wide, self-pollinating and usually do not open widely. The sepals are about 4 mm (0.2 in) long and 2 mm (0.08 in) wide, the petals a similar length but only about half as wide. The labellum is about 4 mm (0.2 in) long and 1.5 mm (0.06 in) wide and is unlobed. Flowering occurs between August and October.

Dendrobium brachypus is endemic to the Australian external territory of Norfolk Island in the Tasman Sea, where it grows on rocks and trees in forest on the slopes of Mount Pitt.
