Taxonomy and naming

Alphitonia excelsa was first described by Eduard Fenzl and reclassified by George Bentham. One of 20 species of the genus Alphitonia in Australia and the Pacific Islands, its specific epithet is derived from the Latin excelsus 'tall'. [1] Other common names include red almond, [2] silver leaf, [2] leatherjacket, white leaf, white myrtle, sarsaparilla tree, and coopers wood.

Description

Leaves and flower buds

This tree reaches a height of 7–25 metres (23–82 ft), by 5–10 metres (16–33 ft) across. [3] The red ash has a spreading shade-producing habit when a larger tree with an overall greyish green appearance. The alternate leaves measure 5–14 cm (2–5.5 in) in length and 2–5 cm (1–2 in) wide and are dark glossy green above and silvery with fine hairs underneath, making an attractive contrast on windy days. The trunk and larger branches bear fissured grey bark, while smaller branches have smoother grey or white bark. It bears small greenish white flowers in late autumn and early winter, followed by globular dark fruit around 1.5 cm (0.59 in) in diameter, [4] which contain two seeds. When young shoots are bruised, they give off a typical odour of sarsaparilla. [5] The flowers are fragrant in the evening. [3]

Distribution and habitat

It grows in eucalypt forests, eucalypt and acacia savannas, gallery forests and rainforests of NSW from Mount Gulaga (previously known as Mount Dromedary) northwards along the coast and inland to the Pilliga scrub, though Queensland and the Northern Territory and into the northwest of Western Australia. [6] Inland forms can be stunted in appearance. It prefers sandy soils.[ citation needed ]

Ecology

It serves as a food plant for the caterpillars of the moonlight jewel ( Hypochrysops delicia ), [7] and the caterpillars of the small green-banded blue ( Psychonotis caelius taygetus). [8]

Uses

Trees are quick growing in cultivation. [4] This is an Australian ornamental tree, with some specimens of high visual appeal. [4] It may be used in amenity planting as a street tree providing shelter. [2] It has also been used in boat-building and cabinet making, its tough timber a light red or brown in colour. [3] [4] It can be a fodder plant for sheep and cattle, and is a useful pioneer species in bush regeneration. [9] Indigenous Australians used the leaves as a soap due to the plant’s high saponin content. [10]

<i>Alphitonia</i> Genus of flowering plants

Alphitonia is a genus of arborescent flowering plants comprising about 20 species, constituting part of the buckthorn family (Rhamnaceae). They occur in tropical regions of Southeast Asia, Oceania and Polynesia. These are large trees or shrubs. In Australia, they are often called "ash trees" or "sarsaparilla trees". This is rather misleading however; among the flowering plants, Alphitonia is not closely related to the true ash trees, and barely at all to the monocot sarsaparilla vines (Smilax).

<span class="mw-page-title-main">Mallee (habit)</span> Growth habit of certain eucalypt species

Mallee are trees or shrubs, mainly certain species of eucalypts, which grow with multiple stems springing from an underground lignotuber, usually to a height of no more than 10 m (33 ft). The term is widely used for trees with this growth habit across southern Australia, in the states of Western Australia, South Australia, New South Wales and Victoria, and has given rise to other uses of the term, including the ecosystems where such trees predominate, specific geographic areas within some of the states and as part of various species' names.

<i>Eucalyptus crenulata</i> Species of eucalyptus

Eucalyptus crenulata, commonly known as Buxton gum, silver gum or Victorian silver gum, is a rare species of medium-sized tree that is found only in the wild in a small area in Victoria but is widely planted. It has rough, compacted bark on the trunk, sessile, egg-shaped to heart-shaped leaves arranged in opposite pairs, flower buds covered with a white, powdery bloom, white flowers and cup-shaped fruit.

<i>Angophora hispida</i> Species of tree

Angophora hispida grows as a mallee, or as a tree to about 7 m (25 ft) in height. A. hispida's small size, especially when compared to its Angophora and Eucalyptus relatives, leads to it being known by the common name dwarf apple. It is native to a relatively small patch of central New South Wales – from just south of Sydney up to the Gosford area. The plant's leaves are sessile (stalk-less) and hug the stem with heart-shaped bases. Its previous name – A. cordifolia – referred to these cordate leaves. Another distinctive feature are the red bristly hairs that cover the branchlets, flower bases and new growth. This leads to the specific epithet hispida.

<i>Dianella caerulea</i> Species of flowering plant

Dianella caerulea, commonly known as the blue flax-lily, blueberry lily, or paroo lily, is a perennial herb of the family Asphodelaceae, subfamily Hemerocallidoideae, found across the eastern states of Australia and Tasmania. It is a hardy plant, growing to a height and width of around 1 meter with grass-like strappy leaves. Blue flowers in spring and summer are followed by indigo-coloured berries. It adapts readily to cultivation and is commonly seen in Australian gardens and amenities plantings.

<i>Bursaria spinosa</i> Species of plant

Bursaria spinosa is a small tree or shrub in the family Pittosporaceae. The species occurs mainly in the eastern and southern half of Australia and not in Western Australia or the Northern Territory. Reaching 10 m (35 ft) high, it bears fragrant white flowers at any time of year but particularly in summer. A common understorey shrub of eucalyptus woodland, it colonises disturbed areas and fallow farmland. It is an important food plant for several species of butterflies and moths, particularly those of the genus Paralucia, and native bees.

<i>Lambertia formosa</i> Shrub of the family Proteaceae, endemic to New South Wales, Australia

Lambertia formosa, commonly known as mountain devil, is a shrub of the family Proteaceae, endemic to New South Wales, Australia. First described in 1798 by English botanist James Edward Smith, it is the type species of the small genus Lambertia. It is generally found in heathland or open forest, growing in sandstone-based soils. It grows as a multistemmed shrub to around 2 m (7 ft) with a woody base known as a lignotuber, from which it regrows after bushfire. It has stiff narrow leaves, and the pink to red flowerheads, made up of seven individual tubular flowers, generally appear in spring and summer. It gains its common name from the horned woody follicles, which were used to make small devil-figures.
