Ricinocarpos brevis | |
Ricinocarpos brevis is a species of flowering plant in the family Euphorbiaceae and is endemic to inland Western Australia. It is a monoecious, densely-branched shrub with narrowly oblong leaves and male and female flowers arranged singly or in small groups.
Ricinocarpos brevis is a monoecious shrub that typically grows to height of 1.0–1.8 m (3 ft 3 in – 5 ft 11 in) and is densely and intricately branched. The leaves are densely hairy and narrowly oblong, mostly 7–30 mm (0.28–1.18 in) long and 1.4–2.0 mm (0.055–0.079 in) wide on a short petiole. The flowers are arranged singly, or with two female, or one female and one or two male flowers. The flowers are conspicuous and arranged on a pedicel densely covered with woolly white, star-shaped hairs. Male flowers are on a thin pedicel 4–8 mm (0.16–0.31 in) long, the sepals covered with woolly, white, star-shaped hairs. Male flowers have egg-shaped, white petals outlined in red, 4.3–5.8 mm (0.17–0.23 in) long and 2.5–3.2 mm (0.098–0.126 in) wide. Female flowers are usually on a stout pedicel 2–5 mm (0.079–0.197 in) long, the sepals densely hairy, the petals white but turning brown, 2.3–4.1 mm (0.091–0.161 in) long and 1.5–1.8 mm (0.059–0.071 in) wide. Flowering has been observed in June, July and November, and the fruit is an elliptic or oval capsule 8–9 mm (0.31–0.35 in) long and covered with star-shaped hairs. [2] [3]
Ricinocarpos brevis was first formally described in 2007 by Rodney John Francis Henderson and Frans Hendricus Mollemans in the journal Austrobaileya , from specimens collected north of Southern Cross in 1990. [2] [4]
This species grows in shrubland on rocky hills and outcrops, and is only known from the Windarling Range north of Southern Cross, at altitudes between 500 and 550 m (1,640 and 1,800 ft). [2] [3]
Ricinocarpos brevis is listed as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions. [3]
Ricinocarpos is a genus of evergreen flowering plants in the family Euphorbiaceae and is endemic to Australia. Plants in the genus Ricinocarpos are monoecious shrubs with leaves arranged alternately along the branches, the edges curved downwards or rolled under. Male flowers are arranged singly or in racemes at the ends of branchlets, with four to six sepals that are fused at the base. There are four to six petals that are longer than the sepals, with many stamens fused to form a central column. Female flowers are arranged singly and are similar to male flowers but with three styles fused at the base and with a deeply branched tip. The fruit is a capsule containing seeds with an elaiosome.
