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 …

Trees Of Western Australia - Swamp Or Flat Topped Yate, Brown Mallet And Four-Winged Mallee, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

The two trees described here under may be readily distinguished when growing as they differ considerably in their barks and general appearance and grow under different conditions, but in common with some other trees of the Southwest each has the mallee form, and the mallee forms are very difficult to distinguish.

The Wedge-Leaved Rattlepod, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

During the last two years, work has been in progress near Fitzroy Crossing (West Kimberley) upon an investigation to determine the cause of Kimber- Iey Horse Disease, commonly known as "Walkabout Disease." The investigations are still in progress, and the findings when completed, will be published elsewhere, but the discovery that Crotalaria retusa L. is a cause—and probably the major cause —of this disease is of considerable importance. Because of this it is considered advisable to assist pastoralists to recognise the plant and by providing information on its habit, occurrence and distribution, to enable them to take steps to minimise …

Trees Of Western Australia - Gimlets And Pear Fruited Mallee, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

Next to the salmon gum, the gimlet tree is perhaps the best-known of the trees of the Eastern Agricultural Districts and the Eastern Goldfields. A thin reddish brown bark, and a fluted or spirally-twisted trunk (especially in the young trees), distinguish at a- glance the gimlet trees or fluted gums from all other Eucalyptus trees. This bark has a thin outer layer which when removed reveals a sappy pale green, inner bark, and sometimes this inner green bark is exposed when the trees shed their reddish-brown outer bark towards the end of summer.

Trees Of Western Australia - Salmon Gum And Scarlet Pear Gum, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

The name salmonophloia, meaning salmon-barked, was given to this tree in 1878 by Ferdinand Mueller, the famous Australian botanist. The title of "Salmon- Barked Gum-Tree" had already been bestowed upon this tree by the early settlers, a name which apparently referred to the colour of the bark in fracture when it resembles the colour of cooked salmon flesh. The external colouration varies from a brownish pink at the end of summer to almost white in winter, usually with greyish-purple patches.

Dahlias - Lifting And Storing The Tubers, F Jackson

Journal of the Department of Agriculture, Western Australia, Series 3

Now that the flowering season for dahlias has finished, arrangements must be made for lifting and storing the tubers. Many losses occur each year during the dormant period and most of these are due either to carelessness or lack of knowledge. While the storage provided for dahlias during the winter months may be thoroughly satisfactory, tubers are often lost because of the treatments received by the plants during the growing period.

Poison Plants Of Western Australia: Isotropis, C A. Gardner, H W. Bennetts

Journal of the Department of Agriculture, Western Australia, Series 3

The genus Isotropis is restricted to Australia. Of the total of nine species six are recorded in Western Australia, two of them being known as "Lamb poisons" while the remainder have no common names. Three are known to be toxic to stock, but concerning the remaining three we have no definite information.

* Poison Plants of Western Australia is an ongoing series of articles. "Toxic Plants of the Genus Isotropis" is the subtitle and primary focus of this article.

Trees Of Western Australia - Tuart And Illyarrie, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

Early settlers of the Swan River Colony soon learnt to value the timber of a tree which the aborigines called "Tooart." It ranked with that of the jarrah in local importance and, because of its toughness, was used for keelsons, stern posts, bridge supports, shafts and wheelright's work—in short for all purposes where great strength, solidity and durability were needed.

Trees Of W.A. Jarrah And Karri, C. A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

In commencing this series, in which a large number of trees will be dealt with, first place must be given to the species of Eucalyptus which include, besides the gum-trees, the various shrubs and mallees which make up a considerable part of the woody flora of South-Western Australia.
