gated by layers, and it thrives best in peat soil, kept rather moist.

Daphné odorant, Fr. ; wohlriechender Seidelbast, Ger.; has the leaves lanceolate, thin, and glabrous ; 
and the flowers terminal and sessile. (Lois. in N. Du Ham., i. p. 28.) Itis a native of China and Japan, 
which was introduced into Britain in 1771, and forms an erect shrub, greatly resembling D. péntica 
in general appearance. The branches are glabrous, and the flowers, which are disposed in terminal 
umbels, are remarkably sweet. The flower buds are pink in their exterior, 
and the petals of the flowers, after expansion, are pink on the outside, though 
they are white within. D. oddra was first brought to England by Benjamin 
Torrens, Esq., and being confounded with the D. indica of Linnzus, from 
which it differs in having sessile flowers and alternate leaves, it was at first 
kept in the stove. By degrees it was tried in a green-house, and is now found 
to stand in the open air in sheltered situations. Du Hamel elasses it with the 
myrtle and the orange as to hardiness. There is a plant in the Horticultural 
Society’s Garden, which has stood out since 1852. 
Varieties. 
# D. 0. 2 variegdta Lodd. Cat., ed. 1836, has variegated leaves, and quite 
white flowers, 
D. o. 3 rubra D. Don, Brit. Fl. Gard., 2d ser., t.320., and our jig. 1192., 
has lanceolate leaves, and flowers of a rich deep pink colour. The flowers 
are produced at the extremities of the shoots; “they are of a dark red 
in the bud state, but become paler and glossy after expansion, and they 
are then highly fragrant.” There are plants in the nursery of Mr. G, 
Smith, at Islington, which appear very nearly hardy, having bornea > 
considerable degree of frost without protection. (See Gard. Mag., xii. 1912 
. 75.) 
a D. hybrida Swt. Brit. Fl. Gard., Ist ser. t. 200., Bot Reg. t. 1177, and 
our fig. 1193.; the D. delphinia of the French gardeners ; and the D. dau- 
phinii, or dauphin’s daphne, of the English gardeners ; has the 
branches pubescent when young, but afterwards becoming 
glabrous. Leaves alternate, oblong-elliptic, glossy above, and 
pubescent beneath. Flowers in terminal groups, nearly ses- 
sile, and covered on the outside with silky hairs. (Swt. Brit. 
Fl. Gard.) This is a highly esteemed kind, and one that is 
much propagated in the London nurseries. _ It grows freely, 
has large handsome glossy leaves, and produces its purplish 
flowers, which have a most delightful fragrance, in great 
abundance. It is supposed to be a hybrid between JD. col- 
lina and D. odora; but it is not known when, or by whom, 
it was originated. It is generally kept in the green-house, 
but would succeed perfeetly in the open air, if planted in light 
sandy soil, against a south wall where it could be protected 
in very severe weather. It flowers under glass in February, 
but would probably be a month or six weeks later in the 
open ground. (Sweet and Lindl.) 
#% D. indica L., the Indian or Chinese daphne, is asmall shrub, with acute 
entire leaves, and terminal sessile flowers. Introduced in 1800, but much 1193 
more tender than either of the preceding species. 
% D. papyracea Wal., D. cannabina Wai., is a Nepal species, from the inner bark of which a soft 
kind of paper has been made in India. It was introduced in 1824.
