This plant, in the state when it bears double flowers, is 

 one of the commonest shrubs in our gardens. It was 

 Supposed to be a species of Corchorus until Professor 

 De CandoUe investigated its affinities, and decided that it 

 was to Rubus and Spiraea that the plant was really allied, 

 and not to any Tiliaceous genus. 



The correctness of this opinion has been fully proved by 

 the single-flowered plant, now represented, for wliicli the 

 country is indebted to John Reeves, Esq. It was imported 

 by him two or three years back, and now exists in several 

 collections. The accompanying figure was made last Sep- 

 tember in the garden of the Horticulturtd Society. 



* Named in compliment to IVIr. William Ker, a botanical collector sent from 

 Kew to China.
