ROCK-GARDEN PINKS 97 
D. chinensis (Chinese or Indian Piunk).—This species is 
really a biennial, and the numerous varieties now in culti- 
vation are very handsome. It is figured in the Bot. Mag., 
Tab, 25, and is there stated to be ‘little better than an 
annual.”” As a contrast to this plate, several varieties 
with laciniated petals are figured in the same periodical, 
Tab. 5536. 
D. deltoides (Maiden Pink).—This is one of the most 
charming species, the flowers being deep pink, with a darker 
centre. There is also a white form which I have raised 
from seed. It has pink spots in the centre, and is very 
pretty for mixing with the rose and pink coloured forms, 
D. fragrans (Sweet-scented Pink).—This should be 
grown as a true rock plant. The solitary flowers are 
white and well rounded, the petals overlapping. Nichol- 
son says it is white, suffused with purple. It is figured 
and described in the Bot. Mag., Tab. 2067. 
D. Holtzeri (Holtzer’s),—This species grows very freely 
in the rock garden. The pink-coloured flowers are not 
large, but they are prettily fringed. 
D. glacialis (Icy). — This is a true alpine species, 
producing its small, almost scentless, purple flowers on 
stems about 3 or 4 inches high. 
D. Libanotis (the Pink of Lebanon).—This is a very 
remarkable species, and seems to have been discovered 
on the highest points of Mount Lebanon by the French 
botanist, Labillardiére. The curious, white flowers, with 
deep red spots at the base of the petals, are borne on 
stems 4 feet high. It first bloomed with a Mr. Lambert, 
who sent flowers to Dr. Lindley, and these were figured in 
the Botanical Register, Plate 1548.
