From The Orchid Column

Dendrobium chrysopterum grows in the Lake Kutubu area in the Southern Highlands Province of Papua New Guinea, according to Lavarack, Harris and Stocker in Dendrobium and its Relatives. It grows as an epiphyte in trees on lowland forest ridges where daytime maximum temperature reaches 87º F.

The candy corn colored flowers are grouped on arching leafless pseudobulbs. The new pseudobulbs have purple tinged leaves.
