1310 ARBORETUM AND FRUTICETUM. PART III. 
If exposed to the sun, the leaves turn back with a kind of twist ; and, instead 
of their natural pure deep green, they assume a brownish tinge. The ber- 
ries are oval, green at first, but black when ripe; and they are a favourite 
food of singing birds : though, as De Candolle observes in the Flore Fran- 
caise, they are poisonous to all other animals. The spurge laurel is propa- 
gated by seeds, like the mezereon ; but, as they will remain two years in the 
ground before they vegetate, they are generally treated like haws, and kept 
for some time in the rotting-heap. It may also be propagated by cuttings ; 
but not readily. It is much used in nurseries, as a stock on which to graft 
the more tender species of the genus; but as, like all the other daphnes, it 
has few roots, it requires to be transplanted with care.

Spec. Char., §c. Evergreen. Leaves obovate-lanceolate, glabrous. Flowers 
bractless, glabrous, in many-flowered upright clusters, each of the long 
partial stalks of which bears two flowers. Lobes of the calyx lanceolate, 
long. (Spreng.) A native of Asia Minor, where it forms a shrub, growing 
to the height of 4 ft. or 5ft., and producing its greenish yellow flowers in 
April and May. It was introduced in 1759, and is frequent in collections. 
Varieties. 
a D. p. 2 rubra Hort. has red flowers, and is supposed to be a hybrid. It 
is rather more tender than the species. 
# D. p. 3 foliis variegatis Lodd. Cat., 1836, has variegated leaves. 
Description, §c. The whole plant, in general 
appearance, strongly resembles the ‘common 
spurge laurel; but the leaves are more oval, and 
shorter; and the flowers, which are disposed in 
twos instead of fives, are yellower, and of a 
sweeter scent. The leaves somewhat resemble 
those of the lemon tree, especially in colour; 
whence Tournefort’s trivial name. When bruised, 
they smell like those of the elder. This fine plant 
was first discovered by Tournefort, on the coast of 
the Black Sea, on hills and in woods; and Pallas 
says that it is also found in Siberia, in thick woods, 
and in the valleys which occur between the ridges 
of lofty mountains. It is, generally speaking, sufficiently hardy to bear the win- 
ters of the climate of London without protection ; but, being disposed to put forth 
its young shoots very early, they are often injured in exposed situations, by the 
spring frosts; “an inconvenience which probably might be avoided by planting 
it in thickets, and under the shelter of trees.” (Bot. Mag., t. 1282.) It thrives 
best in soil similar to that usually prepared for American plants, on the shady 
side of a wall, or in some other sheltered situation, where it will form a very 
handsome bush,¢ ft. or 5 ft. high, and 6 ft. or 8 ft. in diameter. It may be propa- 
gated by seeds or cuttings. Plants, in the London nurseries, are Is. 6d. each.

Derivation. Thymelz‘a is probably derived from thymos, poison, and elaia, or ela, the olive tree, 
in reference to the poisonous qualities of the plant, and its slight resemblance to the olive,
