Taxonomy and naming

The stiff rein orchid was first formally described in 1834 by Adolphe-Théodore Brongniart who gave it the name Platanthera rumphii and published the description in Louis Isidore Duperrey's book Voyage Autour du Monde. In 1835, John Lindley changed the name to Habaneria rumphii. The specific epithet (rumphii) honours Georg Eberhard Rumphius who had given the orchid the name Orchis Amboinica minor.

Distribution and habitat

Habaneria rumphii grows with grasses in open forest and woodland in Australia. It also occurs in Thailand, Laos, Cambodia, Vietnam, Malaysia, Indonesia, the Philippines and New Guinea. In Australia it is found on the Cape York Peninsula and south to Ingham as well as on some Torres Strait Islands. There is a single record from the Northern Territory, where the species is listed as "endangered".
