About Dendrobium falcorostrum Fitzg.
Dendrobium falcorostrum is an epiphytic herb with crowded, yellowish green, spindle-shaped pseudobulbs that measure 120–500 mm (5–20 in) long and 10–15 mm (0.4–0.6 in) wide. Each pseudobulb bears between two and five dark green, leathery leaves, which are narrow elliptic to lance-shaped, 80–150 mm (3–6 in) long and 20–30 mm (0.8–1 in) wide. Its flowering stem is 80–160 mm (3–6 in) long, and holds between four and twenty crowded white flowers that are 32–38 mm (1.3–1.5 in) long and 30–35 mm (1.2–1.4 in) wide. The dorsal sepal of this species is 16–25 mm (0.6–1 in) long and 4–9 mm (0.16–0.35 in) wide. Lateral sepals are 15–30 mm (0.6–1 in) long and 12–15 mm (0.5–0.6 in) wide, while petals are a similar length but narrower than lateral sepals. The labellum is white with purple markings, about 35 mm (1 in) long and wide, and has three lobes. The side lobes curve upwards, and the middle lobe has a Y-shaped ridge with a pointed end along its midline. Flowering occurs between August and October. This species, commonly known as the beech orchid, grows in highland rainforest, mainly on the antarctic beech (Nothofagus moorei), occurring between Lamington National Park in Queensland and the Hunter River in New South Wales.
