Acriopsis emarginata
Acriopsis emarginata, commonly known as pale chandelier orchid, is a species of orchid endemic to Queensland. It is a clump-forming epiphyte with dark green leaves and curved, branching flower stems with many white and cream-coloured flowers.
Description
Acriopsis emarginata is an epiphyte which forms dense clumps with the pseudobulbs surrounded by thin white roots. The pseudobulbs are pale green and onion-like, long and wide. There are between two and four dark green, leathery, narrow egg-shaped leaves which are long and wide. Wiry, branching flower stems long bear large numbers of cream-coloured to pinkish flowers which are wide and have a white, three-lobed, triangular labellum. Each flower has a thread-like pedicel long. The dorsal sepal is linear to oblong, long, about wide and the lateral sepals are fused to form a boat shape long, about wide below the labellum. The petals are linear to egg-shaped with similar dimensions to the lateral sepals. The labellum is long, about wide and has three lobes. The lateral lobes are broadly triangular and the middle lobe is short with two prominent calli. Flowering mainly occurs from June to November.Taxonomy and naming
Acriopsis emarginata was first formally described in 2006 by David Jones and Mark Clements from a specimen collected in the Daintree River valley and the description was published in Australian Orchid Research. The genus name is derived from the Ancient Greek words akris meaning "grasshopper" and opsis meaning "appearance" or "aspect", referring to the grasshopper-like appearance of the column.The specific epithet is a Latin word meaning "notched at the apex", referring to the notch on the labellum callus.
This species was formerly included with Acriopsis javanica but Australian plants are more robust with larger pseudobulbs and leaves and more highly branched flowering stems.
