Asia-Tropical: Sumatera (Sumatera present), Padang highlands present
Malesia: Sumatra (known only from 3 collections from the Padang Highlands).
The Kew isotype consists of 2 fertile fronds, each with 5-lobed apical lamina and 1 pair of forked basal pinnae. C. G. Matthew collected specimens with sterile 5-lobed lamina in the Anai Kloof and one frond of mature size (above described) on Bukit Siboga near Padang Panjang. The latter is intermediate between T. melanocaula and T. angulata in frond form and in sori; it differs from T. angulata in its 5-lobed apical lamina lacking buds and in the lobing of its pinnae.
