Taxonomy and naming

The Norfolk Island orchid was first formally described in 1833 by Stephan Endlicher who gave it the name Thelychiton brachypus and published the description in Prodromus Florae Norfolkicae.[4][5] In 1877 Heinrich Gustav Reichenbach changed the name to Dendrobium brachypus.[6] The specific epithet (brachypus) is derived from ancient Greek words meaning "short" [7]Шаблон:Rp and "foot",[7]Шаблон:Rp alluding to the relatively short pseudobulbs of this orchid, in contrast to those of Dendrobium macropus, described by Endlicher in the same publication.[2][8]

Distribution and habitat

Dendrobium brachypus is endemic to the Australian external territory of Norfolk Island in the Tasman Sea, where it grows on rocks and trees in forest on the slopes of Mount Pitt.[2]

Conservation

This orchid is rare and listed as endangered under Australia's Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).[9][10]
