Eriospermum lanceifolium bears a single, erect, slender (16 cm x 4–5 cm), lanceolate leaf, with undulate (sometimes hairy) margins.

The leaf is a blue colour; it is a tough, leathery texture.

Eriospermum lanceifolium has a lumpy irregular tuber, which is pinkish inside.

It is indigenous to granite or sandstone soils in the Western Cape, South Africa.

It occurs from the Olifants River mountains as far as the town of Albertinia.
