118 THE BOTANY OF WESTERN AUSTRALIA. 
seeds, which are small, like the cultivated lucerne. I observed a new: 
species of Psoralea on the flats of the Irwin, with long spikes of small 
purple flowers ; the leaves are trifoliate, larger than those of red clover, 
and wrinkled; it is a favourite food of cattle and horses. The rare 
Cyclogon canescens of Bentham grows abundantly on the Hutt, and I 
saw two additional species of the genus on the Irwin and the Murchi- 
son; the species on the Irwin is a prostrate plant, much resembling 
native plants of Vicia sativa; the flowers were past, and the seed- 
vessels are those of Qyclogon ; this plant appears among warreu-holes, 
where the road first approaches the species ; on the Murchison it grows 
about a foot high, bearing shorter spikes of flowers than C. canescens, 
but the flowers are much larger and finer than they are in that species ; 
the seed-vessels resemble C. canescens in form. 
(Natural Order Chrysobalanacee).—A species of Stylobasium, pro- 
bably the original species of Desfontaines, grows on all the lime- 
stone hills to the north of the Valley of the Lakes.—The Natural 
Order Myríacee, Suborder Chamelaucie, produces many fine species 
over the whole of the country examined to the north and west. A 
pretty species of Genefyllis, growing about a foot high, with short, 
fleshy, decussate leaves, occurs plentifully on the (sand-plains to 
the east and west of the Hill River; the barren shoots are nume- 
rous, growing close together and quite upright, about a foot high; 
they are generally unbranched and form a sort of column; the 
flowering branches are about the same length, much branched, and 
they lie close to the ground, spreading themselves in all directions 
round the plant which produces them ; ‘the involucres are rose-coloured, 
about an inch wide at the top, and as much in depth; these cups grow 
quite upright, sometimes more than a hundred of them are seen on the 
ground, in a circle round the column of barren branches, and unless 
the plants are carefully examined there is nothing to indicate their 
connection, the flowering branches generally shoot out below ground. 
Another pretty species of this genus grows about a foot high, with 
heath-like leaves ; the drooping heads of the flowers are surrounded by 
glabrous bracts of a deep rose-colour. Two more new species of 
Genetyllis are found with small heath-like leaves and small bracts. The 
genus Chamelaucium produces several fine species. By far the largest 
shrub of the Order known to me is found on sandy ground near all the 
rivers, from the Moore to the Irwin; it grows from fifteen to twenty
