970 ARBORETUM ET FRUTICETUM BRITANNICUM 
Spec. Char., $c. Leaves ovate acuminate, of the form of those of the beech. 
The petioles long and glandless. Fruit small. A native of mountainous 
districts in the most remote parts of Siberia. Persoon has stated that it 
varies with leaves linear-lanceolate. (Dec. Prod.) A low tree, having the 
general appearance of the common apricot, but smaller in all its parts. 
Dahuria, on mountains, growing upon the face of perpendicular rocks ex- 
posed to the sun. Height 6 ft. to 8 ft.; in England 8ft. to 20ft. Intro- 
duced in 1788, Flowers rose-coloured; May. Drupe ?. 
This tree, on the mountains of Dahuria, does not attain a greater height 
than that of a man; but it has a trunk the thickness of the wrist; a rough and 
lack bark, and hard wood. It flowers about the same time as the Rhodo- 
Jéndron dairicum; 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. (Fv. Ross.,i. p. 13.) In British gardens, the 
Siberian apricct forms a tree of nearly the same height as the common apricot, 
of which it appears to us to be the wild form.

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.) A low tree. Dau- 
phiné, in only one locality, and in another in 
Piedmont, where an oil, called huile de marmotte, 
has for a long time been expressed from the ® 
seeds. Height in British gardens 14 ft. to 15 ft. 
in 10 or 12 years; in its native habitats, 6 ft. to 
8 ft, Introduced in 1819. Flowers white or pink ; 
March and April. Drupe ?. 
Seringe suggested that this kind may be the same 
as A, sibirica, and we think it not unlikely to be only 
another variety of the common apricot in its wild j 
state, with toothed leaves. N38: aNliiteanttaeas
