The flowers are those of the currant, and the prickly stems those of the; 

 gooseberry. The fruit is about the -size of black currants, in pendulous racemes,! 

 purplish black, shining, clothed with hairs, and unpleasant to the taste. The] 

 plant forms rather a spreading trailing bush, and is therefore more adaptecij 

 for spreading over rockwork or stones, than for standing erect by itself. Horti-
