déndron ditiricum ; growing on the south sides of the mountains, while the 
latter grows on the north sides. When both these plants are in flower, 
Pallas observes, the north sides of the mountains appear of a purple 
colour, and the south of a rose colour. (7. Ross.,i.p.13.) In British 
gardens, the Siberian apricot forms a tree of nearly the same height as the 
common apricot, of v:hich it appears to us nothing more than a variety. 
There is a specimen in the garden of the London Horticultural Society, 
from which our figure was taken, and which, in 1835, had attained the 
height of 12 ft. in 10 years. It is propagated by budding on the plum ; 
and plants may be obtained in some of the nurseries at the usual price of 
worked trees; viz. ls. 6d. for dwarfs, and 2s. 6d. for standards.

Spec. Char.,§c. Leaves nearly heart-shaped, toothed 
with numerous sharp subimbricate teeth. Flowers 
in groups, almost sessile, scarcely protruded before 
the leaves. (Dec. Prod., ii. p. 532.) A native of 
Dauphiné, which Seringe suggests to be the same 
as A. sibirica, and which, very probably, is only * 
another variety of the common apricot. It grows 
onqy in one locality in France, and in another in 
Piedmont, where an oil called, commonly, in 
France, huille de marmotte, has for a long time 
been expressed from the seeds. In British gar- 
dens, into which it was introduced in 1819, it 
grows to the height of 14 ft. or 15 ft. nm 10 or 
12 years, flowering in March and April.

Derivation. Said to be a word of Asiatic origin; the wild plant, according to Galen, being called 
proumnos in Asia. The Greek name for the plum is prowné : it occurs in Theophrastus. 
Description, §c. The species are chiefly deciduous low trees or shrubs, 
many of them spiny in a wild state; natives of Europe, Asia, and North 
America; and generally thriving best on calcareous soils. Most of them bear 
edible fruits ; and all of them have showy blossoms. In British gardens, they 
are chiefly propagated by grafting, but some of them by layers; and they will 
grow in any soil that is tolerably free, and not overcharged with moisture. 
The epidermis of the bark of the plum, as well as that of the cherry, and per- 
haps that of some of the other genera of Amygdalez, is readily divisible trans- 
versely, and may frequently be seen divided in this manner into rings on the 
tree. Upwards of 30 species are enumerated in our Hortus Britannicus ; but 
we question much if one half of them are not mere varieties. The prices of 
most of the kinds, in British nurseries, are from Is. to 1s. 6d. for dwarfs, 
and 2s. 6d. for standards; at Bollwyller, 1 franc for dwarfs, and 2 francs for 
standards; and at New York, 374 cents for dwarfs, and 50 cents for 
standards.
