Eucalyptus redunca, commonly known as black marlock, [2] is a species of mallee or a shrub that is endemic to Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of between nine and fifteen, lemon-coloured flowers and barrel-shaped fruit.
Eucalyptus redunca is a mallee that typically grows to a height of 1–4.5 m (3 ft 3 in – 14 ft 9 in) and forms a lignotuber. It has grey and pale brown bark that is shed in short ribbons. The adult leaves are narrow-lance-shaped to lance-shaped, 50–75 mm (2.0–3.0 in) long and 9–25 mm (0.35–0.98 in) wide tapering to a petiole 8–15 mm (0.31–0.59 in) long. The flower buds are arranged in leaf axils in groups of between nine and fifteen on an unbranched peduncle 8–15 mm (0.31–0.59 in) long, the individual buds on pedicels 3–5 mm (0.12–0.20 in) long. Mature buds are an elongated spindle shape, 16–26 mm (0.63–1.02 in) long and 3–4 mm (0.12–0.16 in) wide with a conical to horn-shaped operculum that is two or three times as long as the floral cup. Flowering occurs from July to October or November and the flowers are lemon-coloured. The fruit is a woody, barrel-shaped capsule 7–11 mm (0.28–0.43 in) long and 5–8 mm (0.20–0.31 in) wide with the valves near rim level. [2] [3] [4]
Eucalyptus redunca was first formally described in 1844 by Johannes Conrad Schauer in 1844 in Johann Georg Christian Lehmann's book Plantae Preissianae . [5] [6] The specific epithet (redunca) is from the Latin word reduncus meaning bent backwards, referring to the tip of the operculum that is sometimes bent when young. [7]
Black marlock is found on undulating, low ridges mostly along the south coast between Cape Riche and the Fitzgerald River National Park, and inland as far as Ravensthorpe. It grows in shrubland and open woodland in sand-clay soils often over laterite. [2] [3] [4]
The species is associated with the western mallee subgroup which is characterised by several eucalypts including E. oleosa , E. moderata , E. incrassata , E. foecunda , E. eremophila and E. uncinata . The understorey is predominantly shrubby with species of Melaleuca and Acacia along with the occasional Triodia . [8]
This mallee is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [4]
Eucalyptus eremophila, commonly known as the sand mallet or tall sand mallee, is a species of mallet that is endemic to semi-arid regions of Western Australia. It has smooth pale brown and greyish bark, narrow lance-shaped to elliptical adult leaves, flower buds arranged in groups of between seven and eleven with an elongated operculum, and cup-shaped to barrel-shaped fruit.
Melaleuca preissiana, commonly known as stout paperbark, modong or moonah, is a plant in the myrtle family, Myrtaceae and is endemic to coastal areas of southwest Australia. It is a shrub or small tree with papery bark, small leaves and spikes of usually white flowers. It occurs chiefly in areas that are seasonally wet.
Eucalyptus macrandra, commonly known as long-flowered marlock, river yate or twet, is a species of mallee or small tree that is endemic to the south-west of Western Australia. It has smooth greyish bark, lance-shaped adult leaves, flower buds usually in groups of fifteen, pale yellow flowers and elongated cup-shaped to bell-shaped fruits.
Eucalyptus pleurocarpa, commonly known as tallerack, talyerock or tallerack is a species of mallee that is endemic to the southwest of Western Australia. It has smooth bark, broadly lance-shaped to elliptical, grey or glaucous leaves that are arranged more or less in opposite pairs, flower buds in groups of seven, whitish flowers and glaucous, barrel-shaped fruit. It is easily recognised in the field by its form, large, white, waxy leaves and, when in flower, its stamens clustered in four groups.
Eucalyptus preissiana, commonly known as bell-fruited mallee, is a species of small tree or shrub that occurs in an area between Albany and Esperance in Western Australia. It has a spreading habit, smooth bark, elliptical to egg-shaped or oblong leaves, flower buds in groups of three, yellow flowers and cup-shaped, conical or bell-shaped fruit.
Verticordia habrantha, commonly known as hidden featherflower, is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a slender shrub with short, leafy side-branches and long flowering stems with rounded heads of mostly white flowers. Its hairy sepals are mostly hidden by the round, unfringed petals, and as a result, the plant looks like shrubs in the genus Chamelaucium, to which it is closely related.
Eucalyptus foecunda, commonly known as narrow-leaved red mallee, Fremantle mallee or coastal dune mallee, is a species of plant in the myrtle family that is endemic to Western Australia. It has rough bark on the trunk, smooth bark above, narrow lance-shaped adult leaves, flower buds in groups of nine or eleven, creamy white flowers and cup-shaped fruit. It was previously included with the more widespread Eucalyptus leptophylla.
Eucalyptus lehmannii, commonly known as bushy yate, is a eucalypt in the myrtle family Myrtaceae endemic to the south-west of Western Australia. It is a small tree with an oval, spreading form and dense foliage which sometimes reaches to the ground. It is widely cultivated in Australia and the United States because of its ornamental shape and decorative flowers, buds and fruit. There has been some confusion about its classification because of its ability to hybridise.
