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 1837-8. 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.
