Other Species of Prunus Juss.—In consequence of many species of the 
genus Primus being removed to Cérasus; 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. Primus effisa was raised in 1838, in the Hort. Soc. Garden, from seeds 
presented by Baron Jacquin.

CE/RASUS Juss. Tur Cuerry, Lin, Syst. Icosindria Monogynia. 
Identification. Juss. Gen., 340.; Dec. Fl. Fr. 4. -479.; Prod., 2p. 535.; Don’s Mill., 2. p, 504. 
Synonymes. Laurocérasus Tourn. ; Prinus sp. Lin.; Cerisier, Fr.; Kirsche, Ger. ; Ciliegio, Ital. 
Derivation. From Cerasus, the ancient name of atown of Pontus in Asia, whence the cultivated 
cherry was first brought to Rome, by Lucullus, a Roman General, 68 B.c. 
Gen, Char. Drupe globose, or umbilicate at the base, fleshy, quite glabrous, 
destitute of bloom, containing a smooth, rather globose compressed stone. 
(Don’s Mill.) 
Leaves simple, alternate, stipulate, deciduous, or evergreen ; when young, 
conduplicate. Flowers white. Pedicels 1-flowered, rising before the leaves, in 
fascicled umbels, from scaly buds; but sometimes rising after the evolution of 
the leaves, inracemes, from the tops of the branches.—Trees and shrubs, almost 
all deciduous, with smooth serrated leaves, and white flowers ; and, generally, 
with light-coloured bark. Natives of Europe, Asia, and North America. 
Some of them are cultivated for their fruit, and the others as ornamental. 
In British nurseries, the deciduous species are generally propagated by graft- 
ing or budding on the Cérasus sylvéstris, and the evergreens are propagated
