Ricinocarpos linearifolius | |
Ricinocarpos linearifolius is a species of flowering plant in the family Euphorbiaceae and is endemic to eastern Australia. It is a monoecious or dioecious shrub with hairy young branchlets, linear leaves and white flowers, arranged either singly, with two to four male flowers, or a single female flower surrounded by up to three male flowers.
Ricinocarpos linearifolius is a monoecious or dioecious shrub that typically grows to a height of up to 1 m (3 ft 3 in), its young branchlets densely covered with greyish-white, star-shaped hairs. The leaves are linear, 15–45 mm (0.59–1.77 in) long and 1.0–1.3 mm (0.039–0.051 in) wide on a densely hairy petiole 0.8–1.5 mm (0.031–0.059 in) long. The upper surface of the leaves quickly becomes glabrous and the lower surface is densely covered with silky hairs, so that only the midrib is visible. The flowers are arranged either as a single male or female flower, or as clusters of two to four male flowers, or with a single female flower surrounded by up to three male flowers. Male flowers are on a slender, densely hairy pedicel 4–15 mm (0.16–0.59 in) long, the sepals joined at the base and densely hairy, the sepal lobes egg-shaped, 3.0–4.5 mm (0.12–0.18 in) long. The petals are white and egg-shaped with the narrower end towards the base to round, 6.2–10 mm (0.24–0.39 in) long and 4.2–5.5 mm (0.17–0.22 in) wide. Each male flower has 40 to 50 stamens. Female flowers are on a stout, hairy pedicel 5–20 mm (0.20–0.79 in) long, the sepal lobes egg-shaped, 4–5 mm (0.16–0.20 in) long and 2.2–3.0 mm (0.087–0.118 in) wide. The petals are white and egg-shaped with the narrower end towards the base, and 7.5–9.3 mm (0.30–0.37 in) long with smooth edges. Flowering occurs throughout the year with a peak from August to October, and the fruit is a more or less spherical capsule 8.0–9.5 mm (0.31–0.37 in) in diameter and covered with star-shaped hairs.

Ricinocarpos linearifolius was first formally described in 2007 by David Halford and Rodney Henderson in the journal Austrobaileya from specimens collected by Henderson in the northern end of the Blackdown Tableland National Park in 1987. [2] [4] The specific epithet (linearifolius) means "linear-leaved". [2]
This species grows in heath, woodland and open forest between Jericho, Biggenden and Inglewood in Queensland, and near Warialda in New South Wales. [2] [3]
Androstachys johnsonii, the Lebombo ironwood, is a medium-sized Afrotropical tree species, and the sole member of the genus Androstachys in the Picrodendraceae. It is slow-growing, evergreen to deciduous, and dioecious, with flowers that are wind-pollinated. It is native to southeastern Africa and Madagascar, where it generally occurs gregariously on rocky hillsides, particularly in hot and dry situations. It produces a hard, durable wood which is of economic interest. Its specific name commemorates W. H. Johnson, a 19th-century Director of Agriculture in Mozambique. Four related species which are native to Madagascar, are usually placed in genus Stachyandra.
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.
