Dendrobium mortii, commonly known as the slender pencil orchid, is a species of orchid that is endemic to eastern Australia. It is an epiphyte with hanging stems and leaves and flowering stems with up to three pale green to dark green flowers. The flowers have a white labellum with purple markings. It usually grows near the tops of rainforest trees that are often shrouded in mist.
Description
Dendrobium mortii is an epiphytic herb with pendulous stems 1 mm (0.04 in) thick and up to 0.7 m (2 ft) long. The leaves are cylindrical, fleshy and dark green, 40–100 mm (2–4 in) long, 2–4 mm (0.08–0.2 in) in diameter with a longitudinal groove. Up to three pale green to dark green flowers 12–14 mm (0.47–0.55 in) long and 17–20 mm (0.67–0.79 in) wide are arranged on a flowering stem about 10 mm (0.39 in) long. The sepals are 12–15 mm (0.5–0.6 in) long and 2.5–3.5 mm (0.098–0.14 in) wide and the petals are 10–13 mm (0.4–0.5 in) long and about 1 mm (0.04 in) wide. The labellum is white with purple markings, 14–17 mm (0.6–0.7 in) long, 5–6 mm (0.20–0.24 in) wide and has three lobes. The side lobes are upright and the middle lobe curves downwards and has crinkly edges. Flowering occurs from September to November.
