Dendrobium antennatum

Green antelope orchid

A large lowland epiphytic Dendrobium from New Guinea, the Bismarck Archipelago, the Solomon Islands and Cape York. It has cane-like pseudobulbs 30–60 cm long and sprays of long-lasting white-and-green flowers with twisted, upright 'antelope horn' petals. It wants hot, humid, bright conditions all year, with somewhat less water in a mild dry season.

Where it grows wild

An epiphyte of coastal and lowland rainforest, growing on trees rather than in soil. Many GBIF records come from southern New Guinea (the Trans-Fly and Western Province) and Cape York, lowlands with a marked dry season, which suggests it grows on well-lit trunks and branches rather than in deep shade. The sources consulted did not document host trees or its exact position in the canopy.

Sea level to about 1,200 m. The median of 25 recorded elevations is only 30 m, so this is essentially a hot lowland plant.
