Other Species of Vrunus Juss. In consequence of many species of the 

 genus Primus being removed to Cerasus ; and also because of the close re- 

 semblance of one species to another in both genera, there is a good deal of 

 confusion, which cannot be cleared up till the plants are studied in a living 

 state. Prunus effusawas raised in 1838, in the Hort. Soc. Garden, from seeds 

 presented by Baron Jacquin. j

 cherry was first brought to Rome, by LucuUus, a Roman General, G8 e.g. 



Gen. Char. Drupe globose, or umbilicate at the base, fleshy, quite glabrouS; 

 destitute of bloom, containing a smooth, rather globose compressed stone. 

 (Dons Mill.) 



Leaves simple, alternate, stipulate, deciduous, or evergreen ; when young, 

 conduplicate. Floiuers white. Pedicels 1-flowered, rising before the leaves, ir; 

 fascicled umbels, from scaly buds; but sometimes rising after the evolution oj 

 the leaves, in racemes, from the tops of the branches. Trees and shrubs, almosj 

 all deciduous, with smooth serrated leaves, and white flowers ; and, generallyi 

 with light-coloured bark. Natives of Europe, Asia, and North America, i 



Some of them are cultivated for their fruit, and the others as ornamenta; 

 In British nurseries, the deciduous species are generally propagated by graf 

 ing or budding on the Cerasus sylvestris, and the evergreens are propagate.
