Useful Australian Plants.

BY J. H. MAIDEN,
Government Botanist and Director of the Botanic Gardens,

No. 32.—A COTTON-Bush (Kochia villosa, Lindl.) Vernacular names.—This species varies much in the silkiness or cottony nature of the covering of the stem or of the whole plant. It is occasionally called “ cotton-bush," a name sometimes restricted to K. anhylla, looked upon by Baron von Mueller as a variety only of K. villosa; and it also goes under the name of " silky salt-bush.”

Botanical name.-Kochia, in honour of Wilhelm David Joseph Koch, who wrote chiefly on German and Swiss plants during the first four decades of this century. Villosa, Latin adjective, meaning hairy, woolly, downy, in allusion to the stems and leaves.

Botanical description (Flora Australiensis, Vol. V, 186).-An undershrub or shrub, erect, spreading, or decumbent, more or less silky-villous, tomentose, or woolly, or the foliage at length nearly glabrous. Leaves alternate, linear, obtuse, thick and soft in the typical form, terete or flat

tened, from under 4 in. to about } in. long. Flowers solitary in the axils. Fruiting perianth depressed, from quite glabrous, except a slight pubescence on the

edge of the lobes, to tomentose all over, including the wings; the tube short and broad, without vertical wings, the summit flat within the wings; the lobes very short, and closed over the fruit; the dorsal wings united in a single entire or rarely horizontal ring, membranous, and very finely veined, spreading to from

1 in, to nearly 4 in. diameter. Styles, two or three, usually long, united at the base. Bentham observes that this is a very variable species, varying in the foliage and indumentum (silkiness or woolliness), together with the size of the perianth-wing, which, although usually quite entire, is sometimes irregularly lobed. He names the following varieties, both of which are found in this Colony :

humilis, a very dwarf form.
microcarpa, a form with cottony branches, small leaves, and small

fruiting perianth. Value as a fodder.—Though not so valuable as some members of the genus Rhagodia and Atriplex, it is, nevertheless, a very valuable salt-bush, resisting droughts and high temperatures to a remarkable degree, while its nutritive properties are beyond dispute.

Habitat and range.--Occurs in the interior of all the Australian colonies. In our ovn Colony it is by no means scarce in many of the plains aḥout and beyond the Darling, Lachlan, Bogan, &c.
