Ricinocarpos trichophyllus

Ricinocarpos trichophyllus is an open, slender, monoecious shrub that typically grows to a height of 0.7–1.5 m (2 ft 4 in – 4 ft 11 in), its young branchlets covered with white, star-shaped hairs. The leaves are linear to narrowly oblong, 22–45 mm (0.87–1.77 in) long, 1.4–3.5 mm (0.055–0.138 in) wide with the edges turned down or rolled under on a short petiole. Both surfaces of the leaves are sometimes densely covered with soft hairs. The flowers are arranged on the ends of branchlets with one female flowers surrounded by two or three male flowers. Each flower has 5 sepals joined at the base and 5 petals twice as long as the sepals, but the colour of the flowers has not been observed. Male flowers are on a slender pedicel 2.5–10 mm (0.098–0.394 in) long, the sepal lobes 3.0–3.5 mm (0.12–0.14 in) long and 2.0–2.5 mm (0.079–0.098 in) wide. The petals of male flowers are 1.9–3 mm (0.075–0.118 in) long and 1.2–2.2 mm (0.047–0.087 in) wide and there are about 25 stamens. Female flowers are on a stout pedicel 4–7 mm (0.16–0.28 in) long, the sepal lobes 2.7–3 mm (0.11–0.12 in) long and 2.2–2.6 mm (0.087–0.102 in) wide, the petals 2.3–2.5 mm (0.091–0.098 in) long and 1.0–1.3 mm (0.039–0.051 in) wide. Flowering has been observed in February, May and August, and the fruit is a more or less spherical capsule, 6–8 mm (0.24–0.31 in) long and 7.5–10 mm (0.30–0.39 in) wide.^[2][3]

Ricinocarpos trichophyllus was first formally described in 2007 by David Halford and Rodney John Francis Henderson in the journal Austrobaileya, from specimens collected near Nancy's Gorge in the Spirit Hills Conservation Area in the Victoria River region of the Northern Territory in 1996.^[2][4] The specific epithet (trichophyllus) means "hairy leaved".^[2]
