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 fy. 
in Prince’s Catalogue, New York, are marked YY 
at 1 dollar each.

Spec. Char., §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 YAYs 
those of either of the preceding species. (Don’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.
