ROSACEA. 505 



tipped bristles : but the drupaceous mature carpels glabrous, tipped 

 with slender styles. Fruit ovoid, half an inch in length and breadth, 

 apparently red and edible : it is plainly that of a Raspberry, the 

 carpels separable from the conical receptacle. 



The variety, above indicated, appears to differ only in the less 

 pubescent shoots, leaf-stalks, &c, and in the soon glabrate leaflets, &c. 

 Perhaps it is a state of the species growing in deep shade. 



This striking species is most related to the R. spectabilis, Pursh, of 

 Northwest America, which the smoother form considerably resembles. 

 The long-acuminate sepals, equalling the broad petals in length, and 

 the greater prickliness, as well as the usually downy leaves, &c, serve 

 to distinguish them. The wood of the stem is compact, with broad 

 and conspicuous medullary rays, but no obvious annular layers. It is 

 singular that so conspicuous a plant should have hitherto escaped 

 notice. I believe it was gathered, however, by the late Mr. Macrae.
