The linear or deltate leaves, about 20-100 per plant, are mostly in terminal rosettes but with some scattered along the elongate stem.

Inflorescences are 5–11 cm (2.0–4.3 in) long and produces a single pink or mauve flower that blooms from March to August in the southern hemisphere.

Its habitat is recorded as being damp sand near sandstone rocks or on swampy drainage channels.

The form from the lowlands near Darwin is distinguished by its densely hairy leaves with acute apices while the form from Kakadu National Park sandstone escarpments have sparsely hairy leaves with mucronate apices.

All other characteristics of these forms are identical, and this is the reason Bean gave for no taxonomic distinction.
