Aeschynanthus rhododendron

A montane Aeschynanthus of Peninsular Malaysia and Sumatra, described by Ridley in 1896. Most of its GBIF records come from the Malaysian highlands at about 1,400–2,000 m, so it is a cool, constantly wet cloud-forest epiphyte. It needs cool nights year-round and does not suit a warm room.
