It grows close to the ground on fibrous barked plants and only occurs on Lord Howe Island.
Description.
"Plectorrhiza erecta" is an erect epiphytic or lithophytic herb with many long, tangled, cord-like aerial roots at the base of a stem long. There are many bright green, more or less fleshy, leathery, narrow egg-shaped to oblong leaves long and wide. Between two and five yellowish orange flowers with purplish brown blotches, long and wide are borne on a flowering stem long. The sepals and petals are fleshy, long, about wide and curved inwards. The labellum is white to cream-coloured, about long, wide with hairy side lobes and a blunt middle lobe. The middle lobe has a straight spur about long and the column is purple. Flowering occurs from October to December.
Taxonomy and naming.
The upright tangle orchid was first described in 1878 by Robert D. FitzGerald who gave it the name "Cleisostoma erectum" and published the description in his book "Australian Orchids". In 1967 Alick Dockrill changed the name to "Plectorrhiza erecta". The specific epithet ("erecta") is a Latin word meaning "upright".
Distribution and habitat.
"Plectorrhiza erecta" grows near the ground on the fibrous bark of trees and shrubs with its roots spreading over the bark, leaf litter and nearby rocks. It is found near the coast and at altitudes of up to on Lord Howe Island.
