Dicecious. — Aments cylindric, with the scales deeply cleft. 
Perianth cup-shaped, oblique, and entire. Stamens about 8, 
(or from 30 to 100 or more,) inserted on the scale or perianth. 
Fertile florets with the scales and perianth as in the male. 
* Stigmas 3 or 4. Capsule 1 -celled, 2 to 4-valved. Seeds 
numerous, comose, with long soft hairs like wool. 
Trees of the temperate and colder parts of Europe and North 
America, with one species in Asia. The leaves are alternate, 
roundish, or deltoidly cordate, the petiole, for the most part, 
vertically compressed towards the summit, and often glandular 
at the base; the flowers, (as in the Willows, to which they are 
intimately allied,) appearing before the leaves. 
The Poplars are divisible into two sections or subgenera. 
§ 1. Those properly so called, with about 8 stamens, and, 
usually, filiform stigmas. 
§ 2. Those with from 30 to 100 or more stamens, and with 
broad dilated reniform stigmas. — Potameria. These are mostly 
large trees which affect the banks of rivers, and includes Popu- 
lus laevigata , (P. canadensis , Mich, fil.,) P. angulata , P. 
monilifera , P. heterophylla , (P. argentea , Mich, fil.,) and 
probably P. candicans , P. balsamifera , and our P. angusti - 
folia . 
f An old Latin name of uncertain derivation.
