P. CERASIFERA (_syn P. Myrobalana_).--Cherry, or Myrobalan Plum. Native
Country unknown. A medium-sized tree, with an abundance of small white
flowers, 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 _Revue Horticole_, 1881, p. 190.

P. CERASUS (_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
muliplex, and also known under the names of _Cerasus ranunculiflora_ and
_C. Caproniana multiplex_. P. Cerasus semperflorens (_syn Cerasus
semperflorens_), the All Saints, Ever Flowering, or Weeping, Cherry, is
another valuable variety, of low growth, and with gracefully drooping
branches, particularly when the tree is old. It is a very desirable lawn
tree, and flowers at intervals during the summer.

P. CHAMAECERASUS (_syn Cerasus Chamaecerasus_).--Ground Cherry. Europe,
