1258 ARBORETUM AND FRUTICETUM. PART III. 
is considered unwholesome, and even dangerous, to those who are long 
exposed to it. In the Gard. Mag., vol. ix. p. 586., Mr. Godsall, nursery- 
man, of Hereford, mentions that he has seen the pavement of an arbour 
over which a plant of Periploca gre'ca was trained, and in full flower, 
literally covered with dead house-flies, which appeared to have fallen from 
the blossoms, apparently killed by some deleterious property contained in 
them. The capability of extension of this plant is proved by one in the 
Cambridge Botanic Garden having been trained, by means of a jack chain, 
as high as the branches of one of the trees of Sophora japonica, mentioned 
in p. 565. as being 50 ft. high, and which was clear of branches to a con- 
siderable height. When twined round a tree, the periploca forms a deep 
identation in the bark. (See Mag. Nat. Hist., vol. vi. p. 331.) Price of 
plants, in the London nurseries, 1s. 6d. each; at Bollwyller, 60 cents ; and 
at New York, 373 cents.

Leaves lin. long. (Don’s Mill., ive p. 163.) A twining shrub, a 
native of Tunis, on Mount Schibel Jsekel; and of the Island of 
Lampedosa, at the sea side, near Laodicea. An ornamental plant, 
which was introduced in 1800, and is quite as hardy as P. gre‘ca. 
It is rare in British collections. 
fi. P. levigdta Ait.; P. punicefdlia Cav. Icon., 3. t. 217.; is a 
twining evergreen shrub, a native of the Canary Islands, which was 
introduced in 1779; and, though generally kept in green-houses, 
would live through the winter against a south wall, with protection. 
The half-hardy species of Periploca, being deciduous, may be pre- 
served through the winter with much less care than many other 
tender trees and shrubs.
