Distribution
Asia-Tropical, Central West Sumatra present, Mt Kerinci present, Papua New Guinea present
Malesia: Central West Sumatra (Mt Kerinci). In addition to the type, several collections from Papua New Guinea at 1700-2300 m appear to be referable to this species.
Notes
P. sumatrana is related to P. kinabaluensis but smaller, and glabrous on lower surface. New Guinea specimens resemble the Sumatran type, not the plants from Kinabalu, but it is possible that the two should be united.
