Thryptomene biseriata

Thryptomene biseriata is an erect, multi-stemmed shrub that typically grows to a height of 0.3–1.5 m (1 ft 0 in – 4 ft 11 in). Its leaves are more or less round to club-shaped, 1.5–2 mm (0.059–0.079 in) long and sessile with a short point on the tip. The flowers are arranged singly in leaf axils, scattered along the branchlets, each flower on a pedicel 1–2 mm (0.039–0.079 in) long. The five sepals are pink, egg-shaped and 1 mm (0.039 in) long with a distinct claw on the end. The petals are white or pink, slightly longer than the sepals and there are five stamens opposite the sepals. Flowering occurs in March or from October to December.

This thryptomene grows on red sand dunes in the north-west of South Australia and on the Nullarbor Plain and the Great Victoria Desert and Murchison biogeographic regions of Western Australia.
