The specific epithet peltandroides alludes to the similarity of the leaf venation to that of the American aroid genus Peltandra.

[1] The species is a deciduous geophytic, perennial herb, which resprouts annually from a hemispherical corm about 5 cm in diameter.

The flower is enclosed in a spathe, green on the outside, deep reddish-purple on the inside, appearing in late December and January.

[2][1] The species is known only from the tropical Northern Kimberley IBRA bioregion of north-west Western Australia, where the type specimen was collected from Grevillea Gorge in the Synnott Range.

There it grows in shallow sandy soil on a sandstone substrate, in rainforest thickets or with Triodia grasses on rock ledges along the sides of the gorge.
