Dendrobium clementsii

Dendrobium clementsii, commonly known as the Cape York crimp orchid, is a species of epiphytic or lithophytic orchid that is endemic to tropical North Queensland, Australia. It has long stems, tapering pseudobulbs each with a thin, leathery dark green leaf and clusters of short-lived, cream-coloured flowers with a purple labellum.

Description
Dendrobium clementsii is an epiphytic or lithophytic herb with aerial stems up to 1.0 m long. The pseudobulbs are dark green to yellowish and furrowed, decreasing in length and width along the stem from 300 mm long and 5 mm wide. Each pseudobulb has a single thin, leathery, dark green leaf 150-220 mm long and 70-100 mm wide on the end. Clusters of cream-coloured flowers, 14-20 mm long and 20-25 mm wide are arranged at the base of the leaves. The sepals are lance-shaped, 10-12 mm long and 4-5 mm wide and the petals are a similar length but only about 1 mm wide. The labellum is purple, 13-15 mm long, 5-6 mm wide and has three lobes. The side lobes are about 8 mm and have a short fringe. The middle lobe has spreading wavy, hairs about 5 mm on its tip. Flowering occurs sporadically throughout the year and the flowers last less than a day.
