Dianthus alpinus.—This species belongs to the low- 
growing type, and it is one of the prettiest of them. The 
flowers are large for the size of the plant; they are rose- 
coloured, with blotches or spots of deep red. The petals 
are notched, as are those of most of the species. 
D. arbusculus (Shrubby Chinese Pink)—I have not 
seen this in flower, but it is described in Nicholson’s 
Dictionary of Gardening, and it is figured in the Botanical 
Register, Plate 1086. It is stated to be half-hardy only, 
and was introduced from China for the Royal Horticultural 
Society, in 1824, by D. Perks. It is said to flower freely 
from July to October. The flowers are semi-double and 
large, of a delicate, rich-purplish colour ; they are produced 
in terminal panicles. 
D. arenarius (the Sand Pink).—This species is figured 
in the Botanical Magazine, Tab, 2038, and seems to have 
been in cultivation for a long time. It has been described 
as having purple flowers, but the variety illustrated in the 
Bot. Mag. is white, with a faint greenish spot in the 
centre, and covered with short, dark-purple hairs. The 
petals are deeply divided into narrow lobes. 
D. carthusianorum (Carthusian Pink).—This is a very 
distinct and pretty species. It grows freely on any chalky 
soil. The flowers are collected into a close head, twelve 
or more together, on stems a foot to eighteen inches high. 
It does not grow in all gardens so freely as some species, 
It is figured in the Bot. Mag., Tab. 2039. Except in the 
pink colour of the flowers, it does not differ materially from 
D. atrorubens, or D, capitatus. 
D, carneus.—This species forms a neat plant, and 
flowers in any rock garden on the chalk in summer,
