creeping. (Dec. Prod., ii. p. 262.) This kind of 
robinia is a native of South Carolina and Georgia, 
near rivers. It usually grows to the height of 
30 ft. or 40 ft., and was introduced in 1797. The 
flowers are scentless, and are generally of a pale 
pink, mixed with white ; though there are varie- 
ties, or, perhaps, only variations arising from dif- 
ference of soil, with the flowers of a pale purple 
or violet colour. The bark, particularly that of 
the young shoots, which is of a dull red, is 
covered with a clammy substance, which, when 
touched, sticks to the fingers. In every other 
respect, this tree strongly resembles the com- 
mon R. Psetid-Acacia, of which we believe it to 
be only a variety; though so distinct, from the clamminess of its bark, and 
the colour and want of scent in its flowers, that we have kept it apart. The 
clammy matter exuded from the bark of the young shoots is said to have 
been examined by Vauquelin, and found to be a new vegetable substance. 
In England, we have observed that this clamminess differs much in different 
trees, and in some is almost wanting. 

Properties and Uses, §c. This tree, being of less magnitude and duration 
than the common locust, arrives sooner at perfection, and, consequently comes 
sooner into bloom. It also flowers a second time in some seasons, both in 
its native country and in England. As its flowers are large, and conspicuous 
from their colour, the tree well deserves a place in every ornamental plant- 
ation. The wood resembles that of the common locust; but the tree, even 
when full grown, is seldom found with a trunk above 10 in, or 1 ft. in di- 
ameter. In all other respects but those which have been mentioned, the tree 
is, and may be, treated like the common locust. 
Statistics. In the neighbourhood of London, there are no very large trees; those in the Horti- 
cultural Society’s Garden, and in the arboretum of the Messrs. Loddiges, being only about 30 ft. high. 
The rate of growth, in different situations and circumstances, is nearly the same as that of R. Pseud- 
Acacia, for the first 5 or 6 years. In Surrey, at Bagshot Park, 20 years planted, it is 20 ft, high ; at 
St. Anne’s Hill, 30 years planted, it is 33ft. high ; in Sussex, at West Dean, 14 years planted, it is 
$1 ft. high; in Berkshire, at White Knights, 34 years planted, it is 33 ft. high, the diameter of the 
trunk 9in., and of the head 24 ft.; in Cheshire, at Eaton Hall, 12 years planted, it is 18 ft. high ; 
in Worcestershire, at Croome, 30 years planted, it is 45 ft. high. In Scotland, at Perth, in the Perth 
Nursery, 35 years planted, it is 30 ft. high, diameter of the trunk 11in., and of the head 22 ft. In Ire. 
nd aad eee Garden, 20 years planted, and 24ft. high, diameter of the trunk 8 in., and of 
the head 14 ft. 
Commercial Statistics. Plants, in London, are from ls. to Is. 6d., and 
American seeds are 1s. an oz.; at Bollwyller, plants are from 1 franc to | 
franc 50 cents each; at New York, 374 cents a plant.
