964 ARBORETUM AND FRUTICETOM. PART III. 
M.tomentosa Ait., M. canéscens Lour., (Bot. Mag., t. 250. ; and our fig. 707. ;) 
is a native of China, Cochin-China, and the Neelgherry Mountains, in the East 
Indies, with rose-coloured flowers, which appear in June and July. It was 
introduced in 1776, and grows to the height of 5ft. or 6ft. This very hand- 
some plant is not unfrequent in collections, though it has been seldom tried 
against a wall, except in the south of England; where, in Pontey’s Nursery 
at Plymouth, and in other places, it has been found quite hardy. In the 
neighbourhood of London, it might be grafted on the common myrtle; and 
surely some interesting hybrids might be originated between this and the 
common species. There isa variety of M. tomentdsa in some nurseries, with 
leaves less downy than the species, which is known as M. affi‘nis. 
M. tenuifolia Smith in Lin. Trans., ii. p.380., Don’s Miller, ii. p. 836., is 
a native of New Holland, with leaves am inch long and one line broad; and 
with white flowers one half smaller than those of M.comminis. It was in- 
troduced in 1824; but, as its fruit and seeds have not been examined by 
botanists, it may probably belong to some other genus. Some other green- 
house species of MYrtus are described in Don’s Miller, and particularly M. 
nummularia, a creeping species from the Straits of Magellan, and M. myrsi- 
néides from the colder parts of Peru; but both of which will probably prove 
half-hardy, and neither of which have yet been introduced.

delphous. Fruit dry, with \ cell. Ovules ereet. 
Chamelaicium cilidtum Desf. Mém. Mvs., v. p. 40. t. 3. f. B., is 2 
native of New Holland, at King George’s Sound, a very singular shrub, 
with opposite, crowded, linear, triquetrous leaves, and axillary white 
flowers on short pedicels. The flower is girded by two concave bracteas 
before evolution, each terminating in a dorsal mucro, which afterwards 
separates transversely. This very singular shrub is not yet introduced. 
Cilythrix glibra R. Br. (Bot. Cab., t. 587.; and our fig. 708.) is a shrub, 
a native of New Holland, with small cylindrical leaves, and pale-reddish 
flowers, which are produced from Aprilto June. It was introduced in 
1818, and grows to the height of 3 ft. or 4 ft. 
C. ericéedes Cunningh., Don’s Mill., ii. p.1812., is a handsome heath-like \ 
shrub, a native of New Holland, in pine ridges at Bathurst, where it 
grows to the height of from 4 ft. to6ft. It was introduced in 1824, and 
there are plants of it in the Kew Garden. { 
Darwinia fascicularis Rudge in Lin. Trans., xi. p. 299. t. 22., is a de- ; 
cumbent shrub, a native of New Holland, with red flowers. Introduced } 
in 1820, but not very common in collections. ‘ 




CHAP. L. 
OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER PAS- 
SIFLORA ‘CEE. 
Tue common passion flower (Passiflora ceertilea) is so hardy in the neigh- 
bourhood of London, as to flower freely against a wall, in most years, without 
any protection whatever during winter. In very dry sheltered situations, it 
will even endure the open air as a trailing bush ; but as, in this state, it is liable 
to be killed by winters of unusual severity, unless protected, we have decided 
on treating the genus as only half-hardy. It is propagated by cuttings or 
layers, and grows freely in common garden soil. 
Passifiora cerilea L. (Bot. Mag., t.28.; and our 
fig. 709.) is a well-known climbing green-house plant, 
which will also grow and flower freely on garden walls, 
and on the sides of houses with a southern exposure. 
It is a native of Brazil and Peru, and has been in cul- 
tivation since 1699. The prevailing colour of the 
flower is blue; and that of the fruit, which is egg- 
shaped, and about the size of a Mogul plun, is yellow. 
In fine summers, the fruit ripens in the open air, in the 
neighbourhood of London, both against a wall, and 
when the plant is treated as a bush, and allowed to trail 
along the surface of the ground. It ripened fruit in 
the last state, in the Goldworth Nursery, in 1835.
