Ricinocarpos graniticus | |
Ricinocarpos graniticus is a species of flowering plant in the family Euphorbiaceae and is endemic to the southwest of Western Australia. It is a monoecious shrub with linear leaves and creamy white flowers, arranged either singly, or with a single female flower surrounded by one or two male flowers.
Ricinocarpos graniticus is a monoecious shrub that typically grows to height of up to 2 m (6 ft 7 in), its young branchlets glabrous. The leaves are linear, 15–40 mm (0.59–1.57 in) long and 1.2–1.5 mm (0.047–0.059 in) wide on a glabrous petiole 1–2 mm (0.039–0.079 in) long. The upper surface of the leaves is smooth and glabrous and the lower surface is covered with woolly white hairs. The flowers are arranged either as a single male or female flower, or with a single female flower surrounded by one or two male flowers. Male flowers are on a slender pedicel 6–9 mm (0.24–0.35 in) long, the sepals joined at the base and more or less glabrous, the sepal lobes egg-shaped, 4.0–4.2 mm (0.16–0.17 in) long, the petals creamy white and lance-shaped or oblong, 6–8 mm (0.24–0.31 in) long and 1.5–2.4 mm (0.059–0.094 in) wide. Each male flower has about 35 stamens. Female flowers are on a stout pedicel 5–10 mm (0.20–0.39 in) long. Flowering has been observed from June to September, and the fruit is an elliptic capsule about 7 mm (0.28 in) in diameter. [2] [3]
Ricinocarpos graniticus was first formally described in 2007 by David Halford and Rodney Henderson in the journal Austrobaileya from specimens collected in the Darling Range in 2004. [2] [4] The specific epithet (graniticus) means "living on "granitic soil", referring to the granite rock outcrops where this species is found. [2] [5]
This species grows in low scrub on granite outcrops on the Darling Range, with a disjunct population near Newdegate, in the Avon Wheatbelt, Jarrah Forest, Mallee and Swan Coastal Plain bioregions of south-western Western Australia. [2] [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.
