ceolate. (Dec. Prod., iii. p. 206.) A native of moist shaded places 
in Virginia and Carolina. Judging from the plant in the Horticul- 
tural Society’s Garden, it only differs from the species in being a 
little more vigorous.

Deiitzia scabra Thunb. (Don’s Mill., 2. p.808.; Bol. ~ 
Reg., t.1718.; and our fig. 681.) is a climbing or an as- 
cending shrub, with ovate, acuminated, serrated leaves ; 
scabrous stellate hairs; and with white flowers, in com- A 
pound panicles. It is a native of Japan, where the g 
leaves are used by joiners in smoothing and polishing. 
It was introduced in 1822; grows to the height of 6 ft. 
or 7 ft., flowering in May or June; and appears to be 
as hardy as Caprifolium japénicum. It is a very showy 
free-flowering plant, and deserves a place in every col- 
lection. It is readily propagated by cuttings or layers, 
and thrives in any light soil, trained to a wall, and 
slightly protected during severe frosts. Plants, in the 
London nurseries, are 5s. each. 
_ D. corymbosa R. Br., Don’s Mill., 2. p. 808., Royle 
Illust., t. 46. f. 2.; Philadélphus corymbosus Waill.; has 
glabrous leaves, and white flowers. It is a native of 
Kamaon ; grows to the height of 3 ft. or 4 ft., and pro- 
bably is as hardy as the preceding sort. (See p. 173.) There are plants 
in the London Horticultural Society’s Garden. 

D. staminea R. Br., Philadélphus stamineus Waill., has entire, scabrous, lanceolate leaves, and 
bite sweet-scented flowers. It is a native of Nepal, on high mountains; but it is not yet intro- 
uced. 
D. Brunonia Waill., Leptospérmum scabrum JVaill., has ovate leaves, and axillary white flowers. 
It is a native of Kamaon, but has not yet been introduced. The last three sorts are probably only 
varieties of one form. 

CHAP. XLIX. 
OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER MYRTA‘CEER, 
Tuis is one of the most natural groups of woody plants; and, in general, 
may be easily recognised by its opposite entire leaves, full of transparent dots ; 
which indicate the presence of an oil which is fragrant, aromatic, pungent, vola- 
tile: hence the grateful perfume of the leaves, flowers, and fruit of the greater 
number of plants belonging to this order. Like most highly aromatic woody 
plants, the species are chiefly inhabitants of warm climates. The common 
myrtle is a native of Europe; but all the other genera belong to North or 
South America, Africa, Asia, or Australia. A great many of the species are 
very suitable for a conservative wall, from their being evergreen, and from the 
beauty of their foliage and flowers; and many of them, in the neighbourhood 
of London, require little more protection than the common myrtle. All the 
species may be readily propagated by cuttings. The half-hardy, or green- 
house, species, cultivated in British gardens, will be found arranged in the four 
following groups:—I. Melaleicee; II. Euleptospérmez ; III. A/yrtez; and 
IV. Chamelauciéz.
