LXVIII. SALICACEZ!: PO/PULUS. 823 
Its usual period of leafing, in England, is before that of P. trémula. Among 
the Cree Indians, the wood is esteemed to burn better, in a green state, than 
that of any other tree in the country.

The full-formed disk of the leaf is nearly 2. 
round, and 2 or 3 inches in width, with large 
unequal indentations in the margins. The 
most ornamental of all the poplars, when 
the leaves expand in spring, from their s 
deep purplish red colour. 1496. P. (t.) grandidentata.

Derivation. The tree is supposed to be a native of North America, and to be named after the 
village called Athens, on the banks of the Mississippi, where the tree grows abundantly. See 
Gard. Mag., 1840, p. 231. . 
The Sezes. "The female is in the London Horticultural Society’s arboretum ; and was, some years 
ago, in gardens at Bury St. Edmunds, and in the plantations of O. R. Oakes, Esq., at Newton, 
near that town. Willdenow, in his Sp. P/., also mentions the male as the only one that he had 
seen living. It is doubtful whether the male is in Britain.

Spec. Char., &c. Branch round, glabrous. Petiole 
compressed. Disk of leaf roundish ovate, having 
a shallow sinus at the base, and terminating in an 
acute point; serrated with.equal teeth that are 
adpressed ; glabrous, except being slightly ciliated - 
on the edge. (Willd.) A tree, according to Willd., 
wild in the islands of the Archipelago; but, not 
being included in the Prod. Flora Greca, it is more 
probably a native of North America, Height 30 ft. 
to 60 ft. Seeds ripe in May. Cultivated in Britain 
in 1779. Flowers brown; March and April. De- 
cay ing leaves black. 
A handsome vigorous-growing tree, very interesting 
when in flower, from its numerous darkish-coloured 
catkins, which have the plume-like character of those 
of P. trémula, P. trépida, and P. grandidentata. The 
leaves, in their form, colour, and general aspect, re- mo 
semble those of P. trépida, but are longer. 4497. P. gristea.
