Description
Thryptomene oligandra is a shrub that typically grows to a height of 1–5 cm (0.39–1.97 in), sometimes a poorly-formed tree. Its leaves are decussate, egg-shaped with the narrower end towards the base, 3–5 mm (0.12–0.20 in) long and 1.5–3 mm (0.059–0.118 in) wide. The flowers are more or less sessile, arranged in small clusters of three flowers in leaf axils near the ends of the branches. The sepals and petals are similar to each other, the petals about 1.5–2 mm (0.059–0.079 in) long. The five stamens are red or purple and the centre of the flower is yellow.[2]
