Prostrate shrubs with trailing branches to c. 2 m long. Leaves ovate or cordate, 1–3.5 cm long, 0.5–2.5 cm wide, sparsely stellate-hairy above, more densely so below; margins conspicuously serrate, doubly serrate or more or less crenate for all or most their length; petioles 3–20 mm long. Inflorescence 3–12-flowered. Calyx segments 2.5–3.5 mm long, 1–1.5 mm wide, stellate-hairy on both surfaces; petals c. half as long as calyx segments, usually somewhat stellate-hairy; staminodes 5, stellate-hairy. Capsule 5–9 mm diam. Flowers Oct.–Nov.

GipP. Very rare, confined in Victoria to swampy land and lake margins in the Rosedale-Stradbroke-Providence Ponds area.

Plants seem to persist for a few (up to about 10) years post-disturbance before senescing. Germination of soil-stored seeds usually follows flood, fire or earthworks.
