i> considered unwholesome, and even dangerous, to those who are long 

 exposed to it. In the Hard. Jfag., 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 gree'ea 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. 060. as being oO ft. high, and which was clear of branches to a con- 

 siderable height. When twined round a tree, the periploca forms a deep 

 iilentation in the bark. (See Mag. Nat. Hist., vol, vi. p. 331.) Price of 

 plants, in the London nurseries, Is. 0>d. each ; at Bollwyller, 60 cents ; and 

 at New York, 37. \ cents.

 sistent. Cymes trichotomous. Flowers purplish inside, pale yellow 



beneath and round the mouth, with a white spot in the middle. 



Leaves 1 in. long. {Dan's Mill., iv. 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. gra^ca. 



It is rare in British collections. 



|_ P. laevigata Ait. ; P. punicasfolia 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.
