Dendrobium atroviolaceum
Dendrobium atroviolaceum is a species of epiphytic orchid endemic to eastern New Guinea. It was described by English botanist Robert Allen Rolfe in 1890 based on a specimen collected by James Veitch & Sons.
Dendrobium atroviolaceum has been used extensively in the breeding of hybrid orchids. In cultivation, it requires warm, humid conditions and filtered sunlight. It can tolerate night temperatures as low as 5 °C (41 °F) as long as daytime temperatures remain warm. Flowering can occur at any time, but typically occurs from autumn to spring. The flowers may last for three months or more.
Dendrobium atroviolaceum is known from the D'Entrecasteaux Islands and the Louisiade Archipelago in Papua New Guinea. It grows on rainforest trees at altitudes of 200–800 m (660–2,620 ft).
