EUCALYPTUS TREES. . 375d 
America. The fruit is roundish and rather small, 
but of pleasant taste. 
Prunus Chisasa, Michaux.— North America, west 
of the Mississippi. On the prairies it is only 3 to 4 
feet high. Fruit spherical, red, rather small, with a 
tender, usually agreeable pulp. Other species with 
edible fruit occur in North America, such as P. pu- 
mila, L., P. Pennsylvanica, L., P. Virginiana, L., P. 
serotina, Ehrh., but their fruits are too small to ren- 
der these plants of importance for orchard culture, 
though they may also become enlarged by artificial 
treatment. 
Prunus maritima, Wangenheim.—The Beach Plum 
of North America. A shrubby species, of service not 
only for covering coast-sands, but also for its fruit, 
which is crimson or purple, globular, and measuring 
from a half to one inch. It is not necessary to enter 
here any notes on the generally-known species of Pru- 
nus, which have engaged already for years the keen 
attention of many orchard cultivators also in this col- 
ony. Thus we possess, in the country, numerous, 
though not all the best varieties of the cherry (EB: 
avium, L., and P. Cerasus, L.), of the plum (P. do- 
mestica, L.), of the apricot (P. Armeniaca, L.), and 
of the cherry-plum (P. myrobalana, L.), the latter 
Canadian, the others European and Oriental. Infor- 
mation on these and other varieties, to which we have 
added independently also here, may be sought in 
“ Hogg’s Fruit Manual.” The almond (Amygdalus 
communis, L.), and the peach (Amygdalus Persica, 
L.) belong also generically to Prunus, as indicated in 
1813, by F. G. Hayne (‘¢ Arznei Gewaechse,” iv., 38), 
and finally settled by J. D. Hooker (Benth, and Hook. ,
