Description, Sf-c. A deciduous shrub, found 

 in desert places near the rivers Don and 

 Wolga, in a gravelly or sandy soil, producing 

 its yellow flowers in June, and ripening seeds 

 in August. It was introduced in 1786 

 though, being somewhat difficult to propa- 

 gate except by seeds, which, however, in 

 fine seasons, it produces in abundance, it is 

 not so common as it ought to be in British 

 gardens. Grafted standard high on the com- 

 mon laburnum, it forms an object at once 

 singular, picturesque, and beautiful, whether 

 when covered with blossoms, or with its fine 

 reddish pods. Price, in the London nurse- 

 ries, 2s. 6d. each, and standard high, Is. Qd.

Koloutea is also the name of a plant mentioned by Theophrastus. 



Desertion, $c. Shrubs, with impari-pinnate leaves, and flowers disposed 

 in axillary racemes that are shorter than the leaves; few in a raceme. (Dec.

 succeeded by bladdery legumes. Deciduous shrubs, and natives of the middle

 been introduced into Europe are probably only varieties of one species.
