Drosera cuneifolia is a small rosette-forming species of perennial sundew native to the Cape in South Africa.

Drosera cuneifolia produces green somewhat broad carnivorous leaves, up to 7 cm (2.8 in) long.

In early winter, D. cuneifolia produces multiple (up to 20), small, pink to reddish-purple flowers at the end of scapes which can be up to 15 cm (5.9 in) tall.

Flowers individually open in the morning and close by mid afternoon, lasting just one day.

The seeds are very small, black, spindle-shaped, and are released from the capsules that form when the flower has died.
