Asia-Tropical: Malaya (Peninsular Malaysia present); Thailand (Thailand present), Karo Highlands present, Kelantan present, Langkawi present, N. Sumatra present, Pahang present, Perak present, Selangor present, Tapanuli Res present
Malesia: Malay Peninsula (Perak, Kelantan, Pahang, Selangor, Langkawi) and N. Sumatra (Tapanuli Res.: Karo Highlands); probably also in Thailand.
The Sumatran specimens tend to have longer spikes and larger flowers than the Malayan material. No characters have, however, been found on which to base taxonomic separation.
