It is an ephemeral annual that grows from 2–6 centimetres (0.79–2.36 in) tall with obovate leaves that are generally 2–5 millimetres (0.079–0.197 in) long.

Flowers are white and bloom from September to October in its native range.

Its habitat has been reported as being sandy soils in granite outcrops.

[1][2][3] Levenhookia dubia may have also grown in Tasmania, but is currently listed as extinct there under the Tasmanian Threatened Species Protection Act of 1995.

L. Rodway, author of a 1903 assessment of the Tasmanian flora, suggested this species could be found near Brighton, on Mount Field, and on the Bass Strait Islands, but these records are dubious and are not trusted.
