Trees Of Western Australia— The Coolabah, C A. Gardner
Trees Of Western Australia— The Coolabah, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
The coolabah and the grey box are two common tropical trees which closely resemble each other in bark, foliage and other characters, but which differ widely in their soil requirements and in their timbers. Both are numbered among the most valuable trees of the Kimberley district because of the strength and durability of their exceedingly hard timbers and their resistance to the ravages of the termite.

Trees Of Western Australia - The Grey Box, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
In the grey box the rough bark extends to the ultimate branches, unlike that of the coolabah where the smaller branches are usually smooth. The grey box is the common tree of the basalt areas to the north of the King Leopold Range, but unlike the coolabah it is not found along the streams but is more typical of the stony hills and undulating country. Its occurrence is so closely connected there with basalt and andesite, that this particular soil type can at once be mapped by reference to the grey box trees.

Many garden enthusiasts are familiar with a shrub or small tree known as the "Angel's Trumpet" or "Trumpet-flowered Brugmansia." Some nurserymen call it "Brugsmania." There is another garden favourite which does not appear to possess a common name but is an annual or perennial plant from one to four feet in height, of summer growth and carrying erect violet or white trumpet-shaped flowers succeeded by large bristly or prickly pods. Both these are species of Datura. Another species is native to Western Australia while four more are introduced noxious weeds.

Trees Of Western Australia— Lemon-Flowered Gum, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
The Lemon-flowered Gum is one of the lesser-known trees of the Eastern Goldfields. Originally discovered by Richard Helms, botanist to the Elder Exploration Expedition, 60 miles to the south of Victoria Spring, in 1892, it was not rediscovered until specimens were collected by Henry Dean, consulting engineer for the Trans-Australian Railway, near Zanthus in 1909. In that year it received from Maiden, Government Botanist of New South Wales, the name which commemorates Bernard H. Woodward, then Director of the Museum and Art Gallery in Perth.
Trees Of Western Australia— White Mallee, C A. Gardner
Trees Of Western Australia— White Mallee, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
This species is usually found in mallee form, growing from 10 to 18 feet tall, but may at times possess a single stem, and is thus a small tree. Both mallee and tree forms have characteristically a broad 'base or stock, so that frequently in the mallee forms the individual stems arise well above the soil level from a large domelike base. As a tree the stem may be as much as 18 inches in diameter. The species is characterised in the field by its white or pink bark which is covered throughout externally with a white smooth talc-like powder. …

Trees Of Western Australia— Coral-Flowered Gum, C A. Gardner
Trees Of Western Australia— Coral-Flowered Gum, C A. Gardner
Journal of the Department of Agriculture, Western Australia, Series 3
Among the more decorative small trees available for planting in the Eastern Agricultural Areas, there are few more suitable that Eucalyptus torquata. This tree, known also as the "Christmas Tree" of the Coolgardie and Dundas districts usually blooms during December, and its handsome drooping coral-pink blossoms make it a conspicuous object in the woodlands at that season of the year. It was first discovered by L. C. Webster near Coolgardie in 1901, on a stretch of stony dioritic country 25 miles in length and about a quarter of a mile in breadth. It is found at least as far south …
