Bonp. (Swt. Fi. Aust., t.33.), from New Holland ; P. fuilvum Rudge; P. hirtum Willd., from the 
Canary Isiands ; and various other species ; are, in all probability, equally hardy with P. Tobira. P.

Sendcia nepalénsis Dec., a shrub from Nepal, introduced in 1820, and treated as a green-house 
plant; and Bursdria spindsa Cav. figured in Bot. Mag., 1767., a shrub from New Holland, pro- 
ducing a profusion of elegant little white blossoms; are probably as hardy as the species of Pittos- 
por, which have been tried against a conservative wall. Chetranthéra linearis which Dr, Lind- 
ey states (Bot. Reg.,t.1719.), to be “ one of the most beautiful plants in all the flora of New Holland,” 
would be also, if a plant of it could be obtained, well worthy of a trial. 
CHAP. XIV. 
OF THE HARDY SUFFRUTICOSE PLANTS OF THE ORDER 
CARYOPHYLLA'CEX. 
, 
Tuts order is introduced chiefly for the sake of the tree carnation, one of the oldest inhabitants of 
British gardens, and one of the finest plants that can be placed against a conservative wall. There 
are various species and varieties of Dianthus, which, technically considered, are ligneous plants. 
Indeed, the common pink and carnation are shrubs, and that, too, evergreen ; because they do not 
ae to an underground bud, at the end of the growing season, like, for example, Ranunculus 
ris, 
2. 1. Didnthus Caryophillus var. fruticdsus Hort., the shrub 
Clove Pink,or Tree Carnation, in its wild state, is a native of the sou 
of France, of the Alps of Switzerland; and, in England, it is found 
on old ruinous walls near towns, particularly on Rochester Castle, on 
the old walls of Norwich, and on ruins adjoining several other old 
English towns. It has been cultivated in gardens from time imme- 
morial ; and is highly valuable, no less for the brilliancy of its colours, 
than for the aromatic fragrancy of its flowers. ‘Lhe tree variety is 
one which has been originated, in . 
all probability, by training the plant 
against a wall, and thus keeping 
it continually in a growing state 
without permitting it to rest, and 
afterwards continuing this habit by 
ropagating it by layers or cuttings. 
he flowers of the tree carnation are 
not so various and beautiful as those 
of the common dwarf carnation ; but 
they are still objects of very great 
beauty, and are universally admired 
for their symmetry of form, rich 
colours, and grateful odour. Planted 
against an east or west wall, in calcareous loam, and carefully 
trained, a plant will grow at the rate of a foot a year; and, if pro. 
tected duri g very severe winters, it will attain the height of 6 ft. 
‘or 8 ft. In Scotland, in the neighbourhood of Edinburgh, in Dalroy 
Nursery, in 1800, a plant against the west end of a green-house 
covered, in five years, a space 8 ft. wide, and 6 ft. high, flowering 
beautifully every year. 
2. 2. Other suffruticose evergreen a Didnthus ar. 
_ biscula Bot. Reg., 1086., D. arbdreus L. (Bot. Cab.,459., and our fig. 84.), 
D. fruticosus L., and D. suffruticdsus W., are all beautiful glaucous. 
leaved evergreens, which require a little protection during winter, and produce their fragrant pink 
‘flowers from June to August. Siléne fruticisa L., Arena@ria verticillata W., and is spindsa 
(Bot. Mag , 2216., and our fig. 85.), are all beautiful litle evergreens, from 1 ft. to 1} ft. in height.
