The leaves are simple, flat, heart or egg-shaped and may be rounded at the base. The mature leaves are smooth or covered with soft hairs on the upper surface, the underside covered in fine, soft hairs. The leaf margins are flat and scalloped. The single flowers are borne on a thread-like peduncle in leaf axils with 5 small to medium sized bracts. The sepals and petals are whorled around the centre floral receptacle. The fruit are a hairy capsule 2–7 mm (0.079–0.276 in) long containing 2 seeds that are dispersed at maturity. [2]

[3] [4] The specific epithet (Tremandra) is derived from the Greek for "hole" and "anther", referring to the anthers bursting open through a hole. [5]
