Scientific name: Trianthema cypseleoides

Trianthema cypseleoides was a small ground-dwelling herb with short, smooth lateral branches. The leaves were either egg-shaped, club-shaped or circular, approximately 0.5 cm long, with a slender leaf-stalk, dilated at the base with thin, membranous margins. The flowers were in loose flat-topped clusters. The bracts (modified leaves) immediately beneath the flowers were thin and membranous. The petals were broad, rounded and approximately 2 mm long. There were 7–10 stamens (male reproductive part of flower). Both the fruits and seeds were smooth (National Herbarium of New South Wales 2007; Prescott 1984).

Trianthema cypseleoides is known only from the type specimen collected from the Hawkesbury River, NSW in 1839 (National Herbarium of New South Wales 2007; Prescott 1984).

The reasons for the decline and extinction of Trianthema cypseleoides are unknown.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
