allied to C arborcscenSj but differs in the flowers being larger

Native of the Russian empire. Perhaps Robinia Mongolica of

Cult. All the species of this genus are well adapted for 

 shrubb 



flowered peduncles, and yellow flowers. The place which this 

 genus should occupy in the order is very doubtful, in conse* 

 quence of the structure of the legume being imperfectly known.

 gardens, but seldom or never flowers, probably from the want of 

 the saline principle in which it naturally grows.

 and is increased by layers or by seeds. Being rather tender 

 should be protected by a mat in winter.
