Spec. Char., ^-c. Branches pendulous, scaly, the young 

 shoots pubescent. Leaves ovate, acute, coarsely den- 

 tate, hairy beneath. Racemes terminal, compact, 5 9- 

 flowered. Ovary half superior. Style 4-cleft. Calyx spread- 

 ing from thefruit. (Lindl.) A hardy vigorous-growing shrub, 

 having a weeping appearance in consequence of producing 

 numerous slender side shoots. America, on the north- 

 weet coas-t, on the Columbia River, in woods. Height 8 ft. 

 to 10ft. Introduced in 18-23. Flowers white, scentless, very 

 hairy; end of July. Fruit large, smooth ; ripe in October. 



The leaves are bright green, rather small, ovate, pointed, 3-nerved at the 

 base, and coarsely serratecl. The flowers are large, pure white, and produced 

 m great profusion. The species is readily known by its deeply serrated 

 leaves, its nearly superior fruit, its broad spreading calyx, and the com|)act 

 manner in which its flowers are arranged. It is the latest in flowering of all 

 the species, and one of the m.ost showy. It was not at all injured by the 

 severe winter of 1837-8. It grows in any common soil, and is readily in- 

 j creased from seeds, or by cuttings of the half-ripened shoots in August. It 

 1 was named in compliment to Mr. Robert Gordon, foreman of the arboretum, 

 'Ji the Hort. Soc. Garden, who has paid great attention to this genus.
