Description. 



P^'^HE Robinia viscosa usii- 

 ^ h H 1^ ally grows to a height of 



1)^ LI 1^ thi; 



J 1^ iiiirty or forty feet, with 



_ . i^^i a diameter of six to 



twelve inches. The bark, particularly of young 

 shoots, is of a dull red, and is covered with a 

 viscid substance, which, when touched, adheres 

 to the fingers. In every other respect, this tree 

 strongly resembles the preceding species. The 

 branches are armed with spines, Avhich, how- 

 ever, are smaller and less numerous. The 

 foliage is thicker, and of a dusky green. The 

 leaves are five or six inches long, and are com- 

 posed of opposite leaflets, with a terminal odd 

 one. The leaflets are about an inch in length, 

 oval, nearly sessile, smooth, and of a fine tex- 

 ture. The flowers usually appear in June and 

 July, but in some seasons, they put forth a sec- 

 ond time, both in England and in the United 

 States. They occur in numerous, open bunches, four or five inches long, and 

 are of a beautiful rose-colour, mixed with white, but are destitute of fragrance. 

 The seeds, which are small, are contained in hairy pods, two or three inches 

 long, and about half of an inch broad. 



Geography and Hialory. In its natural liabitat, this species appears to be 

 chiefly confined to the Alleghanies, in the western parts of (Georgia and the Car- 

 olinas, although it is found on the banks of the rivers in these states, particularly 

 on the Savannah. It was introduced into P>ritain in 1707. and istnuchcuhi- 

 vated for ornament in various parts of Europe.
