« Cultivated species. 

 R. specibsum, Showy Flowering-Gooseberry, of California: cult, 

 for ornament, especially in England, likely to succeed in Southern Middle 

 States, is trained like a climber ; has small and shining leaves, 1 - 3 very hand- 

 some flowers on a hanging peduncle, the short-tubular calyx, petals, and long- 

 E rejecting stamens deep red, so that the blossom resembles that of a Fuchsia ;
