 to 10ft. Introduced in 1823. Flowers white, scentless, very 

 hairy ; end of July. Fruit large, smooth ; ripe in October. 829. p. Gord'onia. 



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

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

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

 leaves, its nearly superior fruit, its broad spreading calyx, and the compact 

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

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

 severe winter of 1 837-8. It grows in any common soil, and is readily in- 

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

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

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