Scientific name: Tetratheca fasciculata

Common name: Cronin's Tetratheca

Cronin's Tetratheca was a compact shrub, less than 20 cm tall, with numerous slender stems arising from the top of a stout, woody rootstock. The stems had few branches and were covered with fine white hairs. The leaves were approximately 5 mm long, hairy, and arranged alternately on the stem. The shape of the leaves was elliptic to ovate. The single flowers had four tongue-shaped, dark pink petals, up to 8 mm long, and eight stamens (male reproductive part), up to 3 mm long. The anther (pollen producing part) was somewhat curved, narrowing at the apex. The ovary had a covering of short, dense hairs (Brown et al. 1998).

Cronin's Tetratheca was collected from the Wagin area, Western Australia, approximately 230 km south-east of Perth. The species was collected from 'Sources of the Blackwood River' in 1889, and again in 1895 from near Lake Wagin (Brown et al. 1998; Thompson 1976).

There are no details of the habitat in which Cronin's Tetratheca was found (Brown et al. 1998).

The time of flowering and reproductive mechanism of Cronin's Tetratheca is unknown (Brown et al. 1998).

The reasons for the extinction of Cronin's Tetratheca are unknown (Brown et al. 1998).

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.
