Description

Dendrobium antennatum is an epiphytic orchid with cylindrical, yellowish green pseudobulbs 300–600 mm (10–20 in) long and 20–25 mm (0.8–1 in) wide. There are between eight and twelve egg-shaped leaves 80–140 mm (3–6 in) long and 30–40 mm (1–2 in) wide on the upper two-thirds of the pseudobulb. The flowering stems emerge from upper leaf axils and are 200–350 mm (8–10 in) long with between three and fifteen flowers. The flowers are mostly white, 50–60 mm (2.0–2.4 in) long and 40–50 mm (1.6–2.0 in) wide but with pale green petals. The dorsal sepal is a narrow triangular shape, 16–20 mm (0.63–0.79 in) long, 4–5 mm (0.16–0.20 in) wide and usually curled to one side. The lateral sepals are also narrow triangular, 13–16 mm (0.5–0.6 in) long, 6–7 mm (0.2–0.3 in) wide and curved backwards. The petals are linear to lance-shaped, 35–40 mm (1–2 in) long, about 4 mm (0.2 in) wide, stiffly erect and twisted. The labellum is white with purple stripes, about 25 mm (1 in) long and 12 mm (0.5 in) wide with three lobes. The side lobes curve upwards and the middle lobe in pointed with five ridges along its midline. Flowering occurs from March to December and the flowers are long-lasting. [4] [5] [6] [7]
