Description
Similar to E. sumatranum in rhizome-scales and spores, but with thinner, much longer fronds.
Distribution
Asia-Tropical, Central West Sumatra present
Malesia: Central West Sumatra. Only known from type collection.
Notes
This is closely related to E. sumatranum, and was collected in the same region, but is so much larger that I think it should stand as a distinct species. It should be noted that Alston also collected typical E. sumatranum, and no intermediates between the two have been found.
