RIVER CRAB APPLE. 
Pyrus rivularis (3. levipes, in these the pedicels are also 
glandular. 
What this plant may become by cultivation, cannot 
yet be determined. The Siberian Crab, (now so orna- 
mental and generally cultivated,) which also affects the 
alluvial borders of streams and rivers, round Lake 
Baikal, and in Daouria, according to Pallas, in its native 
soil, it only attains the height of 3 or 4 feet, with a trunk 
about as thick as a man’s arm, and full of tortuous 
branches. The berries, also, in Pallas’ figure, (Flora 
Rossica, vol. 1. tab. 10.) are not so large as ordinary 
peas, and pyriform or attenuate at the base like a pear. 
All this tribe of plants, so eminently serviceable both 
for ornament and use, deserve cultivation in a pre- 
eminent degree, and the present species has also the 
advantage of being perfectly hardy in all temperate and 
even cold climates, as it stretches along the coast nearly 
to the vicinity of eastern Siberia. 
All the plants of this section of Pyrus are natives of 
temperate Europe and northern Asia.

A branch of the natural size. a. The apple. 
Narrow Leaved Crab Apple, ( Pyrus angustifolia, 
Aiton.) This appears to be scarcely more than a 
variety of the Pyrus coronaria ; distinguishable indeed by 
its narrower leaves, usually entire, which are often acute 
below, but as the styles are neither perfectly distinct 
nor constantly glabrous, and that the young leaves are 
also pubescent, no sufficient distinction remains. The 
fruit is likewise wholly similar.
