Name

The name "Acriopsis, which is derived from the Greek akris, locust and -opsis, resemblance, refers to the unusual column that resembles the shape of a locust"[3]; while emarginata derives from 'emarginate' - to have a shallow notch at the apex.[2] It is also known as the 'Pale Chandelier Orchid'.[1][2]

Description

Acriopsis emarginata "is an epiphytic orchid with dense, onion-shaped pseudobulbs and a mass of white aerial roots (Jones, 2006). This species has 2–4 dark green leaves, up to 20 cm long and 2.5 cm wide. Many flowers are born on the wiry, branched panicles. Flowers are 5 mm across, cream or pinkish, with a white, three-lobed, triangular labellum (modified petal at the front of the flower). Flowering occurs between June and November (Jones, 2006). Flowers last 2–4 days and are pollinated by native bees (Jones et al., 2006)."

It has 2-4 leaves, 150 to 200 mm long and 20 to 25 mm wide.[1][2]
