Spec. Char., ^c. Leaflets acute, almost equally serrated, glabrous, as is the 

 petiole. PoLiies globose, of a purplish tawny colour. {Dec. Prod.) A 

 tree, closely resembling the common mountain ash. Canada and New- 

 foundland, in woods. Height 15 ft. to 20 ft. Introduced in 1782. Flowers 

 white; May. Fruit bright scarlet; ripe in September, Decaying leaves 

 yellowish green. Naked young wood dark purplish. 



It is, apparently, a more robust-growing tree than the European mountain 

 ash, with larger leaves, shining above, and smooth beneath ; but, in reality, it is 



more tender. Though it has been many years in the country, we do not 

 I know of a large, old, handsome specimen of it any where. It is propagated 

 , by grafting on the common mountain ash. On account of the brilliant colour 



ot the fruit, and the large size of the bunches in which it is produced, this 

 , species well deserves a place in collections.
