and flowering in May. From the plants of this 

 sort in the Horticultural Society's Garden, we 

 are convinced that it is nothing more than a 

 variety of H. tetraptera, from which it differs 

 chiefly in having the leaves somewhat downy. 

 It well deserves a place, however, in every collec- 

 tion, even if it were less distinct than it is ; and, 

 to make sure of the continuance of the kind, it 

 ought to be propagated by layers or cuttings, ra- 

 ther than by the usual mode of seeds ; which, in 

 this species, as in the preceding one, are ripened 

 in abundance in England. Plants of this sort 

 in Prince's Catalogue, New York, are marked 

 at 1 dollar each.

Spec. Char., S^c. Leaves ovate, acute, serrated. Petioles mooth sand even. 

 Pedicels elongated. Fruit with 2 large opposite wings, and 2 obsolete 

 ones. Flowers octandrous. Leaves much larger than 

 those of either of the preceding species. (Do?i , s Mill., iv. 

 p. 7.) A tree, 10 ft. high, a native of Georgia and Caro- 

 lina, in shady places, on banks of rivers. It was intro- 

 duced in 1758, and flowers in April and May. The leaves 

 of this species are broad, resembling those of Styrax 

 grandifolium, with which, as it does not frequently flower 

 in a young state, it is generally confounded in nurseries. 

 The only flowering plant that we know of, in the neigh- 

 bourhood of London, is against a wall in the arboretum 

 of Messrs. Loddiges, where it ripens seeds. It is com- 

 monly propagated by layers ; and the price of plants, in the London nurseries, 

 is 5s. each ; at New York, 1 dollar.
