From NE India to Thailand and Malesia; in Malesia: Sumatra (incl. Riouw Arch.), Malay Peninsula, Java, Borneo.

Notes

2In the Malay Peninsula, the species is represented by a form with lanceolate laminas, often with one or two broad lobes in the lower part of the lamina and with up to 17 pairs of lateral veins which depart at angles of (almost) 90° from the midrib and are mostly straight (var. oblonga). This form is connected with intermediates with the more typical and common form, also in Borneo and Sumatra. 6The differences between this species and F. heteropleura, F. kuchinensis, and F. parietalis are listed under the ﬁrst named species. 1Corner (1960, 1965) recognized two subspecies, subsp. sinuata and subsp. cuspidata. However, these taxa are in a number of characters sufﬁciently different to regard them as species. There is a slight problem that F. sinuata is represented by some small-leaved specimens in Sumatra and Java, but these can be distinguished from F. cuspidata in the persistent epidermis of the petiole, the flat margin of the lamina, the scabridulous leafy twigs, lower surface of the lamina and/or the (sub)globose ﬁg receptacle, the usually curved lateral veins, and/or the usually somewhat larger and usually subglobose ﬁg receptacles, often with longer peduncles with the bracts mostly scattered. The colour of mature ﬁgs may be different as well. Moreover, the altitudinal ranges of the two species are different, although there is some overlap. 4For a single collection the label indicates as provenance the Moluccas, but it is doubtful whether that indication is correct. It has not been included in the distribution paragraph. 5Two collections from Sumatra (Gunung Leuser Nature Reserve) deviate in the length of the petioles, being 1.2-3.5 cm long. 3Two collections from Mt Singgalang (W Sumatra), belonging undoubtfully to this species, have been made at altitudes between 2000 and 2400 m, far above the common maximum altitude of this species (1400 m) as well as above that of the closely related F. cuspidata.
