Leaves 6–8 per stem, pinnate, spreading; sheaths to 30 cm long, tubular, forming a crownshaft; petiole to 25 cm long; rachis to 75 cm long; pinnae 7 per side, 20–25 x 15 cm, ± trapezoid, sides not parallel, nerves diverging, apical margin praemorse.

Because of its very localized distribution, this species should be considered rare and of moderate concern in Thailand.
Similar to the sometimes co-occurring I. polymorpha, but the latter differs in its inflorescence with a longer peduncle (10 cm or more) and the elongate, unlobed fruit. It is apparently very localized.
Global — Peninsular Malaysia.
Thailand — PENINSULAR: Satun, Yala, Narathiwat.
This species occurs in moist to wet forest, 600–1000 m altitude.
There is no recorded use for this species but it makes a fine ornamental.
