Dendrobium lobbii

Straggly rush orchid

A terrestrial Dendrobium with thin, wiry, reed-like stems 20–60 cm long and narrow leaves, which grows among rushes and sedges in swamps and along streams from Thailand and Vietnam through Malesia to New Guinea and northern Australia. Its small white to greenish flowers often barely open and self-pollinate. It is a warm, sun-loving wetland plant, very unlike the usual epiphytic Dendrobium.

Where it grows wild

It grows in open wetlands: swamps, soaks and stream margins among rushes and sedges, with its roots in permanently or seasonally wet ground and its stems supported by the surrounding vegetation.

Thirty-one GBIF records carry an elevation, from 20 to 1440 m with a median of 80 m. Most are lowland swamps on Cape York and in Arnhem Land; the higher records are from New Guinea and Malaysia.
