which are particularly attractive if they escape the early 

 spring frosts. . It is of stout, branching habit, with a 

 well-rounded head, and has of late years attracted a good 

 deal of notice as a hedge plant. P. cerasifera Pissardii, 

 the purple-leaved Cherry plum, is a remarkable and 

 handsome variety, in which the leaves are deep purple, 

 thus rendering the plant one of the most distinct and 

 ornamental-foliaged of the family. It produces its white, 

 blush-tinted flowers in May. It was received by M. A. 

 Chatenay, of Sceau, from M. Pissard, director of the 

 garden of His Majesty the Shah of Persia. When it 

 flowered it was figured in the Bevue Horticole, 1881, p. 190. 



P. Cekasus (syn Cerasus vulgaris). — Common Cherry. 

 A favourite medium-sized tree, and one that lends itself 

 readily to cultivation. As an ornamental park tree this 

 Cherry, though common, must not be despised, for during 

 summer, when laden with its pure-white flowers, or again 

 in autumn when myriads of the black, shining fruits hang 

 in clusters from its branches, it will be readily admitted 

 that few trees have a more beautiful or conspicuous 

 appearance, P. Cerasus flore-pleno (double-flowered 

 Cherry) is a distinct and desirable variety. P. Cerasus 

 multiplex is a very showy double form, more ornamental 

 than P. Avium multiplex, and also known under the names 

 of Cerasus ranunculiflora and C. Caproniana multiplex. 

 P. Cerasus semperflorens {syn Cerasus serwperflorens), the 

 All Saints, Ever Flowering, or Weeping, Cherry, is 

 another valuable variety, of low growth, and with grace- 

 fully drooping branches, particularly when the tree is old. 

 It is a very desirable lawn tree, and flowers at intervals 

 during the summer. 



P. Chajlecebasus (syn Cerasus Chamaecerasus). — 

 Ground Cherry. Europe, 1597. This is a dwarf, slender- 

 branched, and gracefully pendent shrub, of free growth, 

 undoubted hardihood, * and well worthy of extended 

 cultivation. The variety G. Chamaecerasus variegata has
