must be kept within bounds by annually lifting the clumps and reducing 
them. They are most useful for covering unsightly places in the garden. 
Propagation is easily effected by dividing the clumps. All the species 
are hardy.

SWAN RIVER DAISIES 
Natural Order Composira. Genus Brachycome 
BRACHYCOME (Greek, brachys, short, and kome, hair, alluding to the 
shortness of the pappus-hairs), A genus comprising about thirty species 
of annuals and perennials, very similar to Bellis (the Common Daisy) in 
structure. Bellis, however, has no pappus, whilst Brachycome has. 
Another point in which the genera differ is found in the character 
of the bracts forming the involucre: in Brachycome these have a 
membranous margin. The species are all natives of Australasia. 
BRACHYCOME DIVERSIFOLIA (differing-leaved). Leaves 
variously cut and lobed. Flower-heads yellow ; summer. 
B. GLABRA (smooth). Leaves fleshy, cut in a pinnate manner ; the 
slender segments variously cut, upper ones almost entire, fringed at the 
edges. Flower-heads solitary, on long footstalks ; yellow disks and 
white rays with a violet tinge beneath. 
B. IBERIDIFOLIA (Iheris-leaved), Stems erect, smooth, branched, 1 
foot high. Leaves pinnate, segments very slender. Flower-heads blue- 
or white-rayed with dark-coloured disks; June to September. Swan 
River (1843). Plate 128, 
Gilitvidion The species mentioned above are hardy annuals, and 
must be raised from seed. These may be sown in Mare 
on a gentle hot-bed, and the seedlings planted out when large enough and 
sufficiently hardened; or the seed may be sown on a sunny border out 
of doors, towards the end of April or beginning of May, and the seedlings 
thinned out to a distance of six inches apart. The plants like a sunny 
position, and provided they have this, soil is of secondary importance, 
though their preference ig for dryish situations. wees:
