Cerasus (CHERRY). There are three groups of Cherries, viz.: (1) the 

 Cherries proper, (2) the Bird Cherries, and (3) the Laurel Cherries, all 

 put under the genus Prunus by botanists. Amongst the first group is 

 0. Avium, the British Wild Cherry or Gean, a fine tree 20-30 ft. high, 

 with white flowers and black fruits. C. vulgaris, another British tree, 

 has several forms, including flore pleno and multiplex, both double white; 

 and lutea flore pleno, semi-double, tinted with yellow. C. serrulata, a 

 splendid Chinese Cherry, has clusters of pale- white or rose-tinted double 

 flowers. C. Pseudo-cerasus, another Chinese species, has single and double 

 varieties with white or rose-pink flowers, Watereri and Jas. H. Veitch 

 being among the best doubles. 



Among the Bird Cherries are the native C. Padus, with several varie- 

 ties, like argentea, aucubcefolia, and flore pleno the latter a fine double 

 form. C. Mahaleb is largely used for stocks for budding and grafting. 



The Cherry Laurel (C. Lauro-cerasus) is grown in thousands, and has 

 many varieties, the best known being caucasica, colchica, rotundifolia, 

 macrophylla, Ottini, &c., all of which stand clipping well. Zabeliana 

 is a very distinct and pretty variety, with smaller and narrower leaves, 

 closely arranged. 



The Portugal Laurel (C. lusitanica) is also largely grown for hedges 

 and game coverts. The variety myrtifolia has smaller leaves, while 



azorica has larger leaves than 

 the type. 



Cercis Siliquastrum (JuDAS 

 TREE). This is the best known. 

 It grows 20-30 ft. high, and has 

 peculiar bluntly heart-shaped 

 notched leaves and clusters of 

 bright - purple, pale - rose, or 

 whitish flowers in May. It re- 

 quires protection in cold places. 

 C. canadensis has bright-rose 

 flowers. Increased by seeds 

 and layers. 



Chionanthus virginicus 

 (FRINGE TREE). A pretty North 

 American tree or shrub, with 

 oblong lance-shaped leaves and 

 drooping clusters of pure-white 

 flowers with narrow fringe-like 

 petals. C. retusus (fig. 417), 

 from China, has leaves woolly 

 beneath, and white sweet-scented 

 flowers. Increased by seeds, cuttings, or layers, or grafts on stocks of the 

 Common Ash. 



Choisya ternata (fig. 418). A beautiful evergreen, known as the Hexi- 



. in.Chionanthiis retusus.
