The oak-leaved Chenopodium is supposed to contain essential oil; it was formerly used by the settlers as a vegetable, and is proved to contain carbonate of soda, so that, as Mr. Drummond suggests, "it would be worth inquiry at what price we could afford barilla as an export." The Erythraea Australis is, we are informed, a good substitute, and is used as such, for hops; and one species of tobacco is indigenous to the colony. The sow-thistle of Swan River was, in the early days of the settlement, used as a vegetable, but is now eaten only by the domestic animals, by whom it is much relished. As a salad, it is said to be scarcely inferior to endive. The Helicrysum, a biennial of the Vasse district, is a grateful fodder for horses, and the Morna nitida for goats, sheep, and cattle, as are also several species of Picris and other shrubs. There is also a native celery, which forms a poor substitute for that of Europe; two varieties of this species are mentioned -- the Conna, of which the roots are eaten by the natives after being peeled, and the Kukire, the foot of which resembles the carrot in appearance, with the smell and colour of the parsnip. The wild carrot is also an excellent vegetable, and from its root rich wine has been extracted. The order Eryngo has a species of which the roots when candied have great restorative powers. Of the Hederoma latifolia, Dr. Lindley remarks, that its half-ripe fruits, if sent to Europe, would give several original and valuable scents to the perfumer. Of the sea-weeds, one particular species, supposed to be the Fucus amylaeceus, thrown in great quantities upon the coast, is mentioned as forming when boiled, sweetened, and spiced, a nutritious and beautiful jelly of a fine rose colour; and as it appears that it may be dried without injury and preserved for years, it would be of value as an export. The catalogue of indigenous fruits is not very extensive, but one species, belonging to the order Epacrideae, is reported to bear very palatable berries. The Vasse apple, of the size of a peach, is stated when boiled with sugar to be an agreeable sweet-meat.
