Populus tremuloides (Aspen)
Salicaceae (Willow Family)

Montane, subalpine. Woodlands. Spring.

"Populus" is a classical Latin tree name given to this genus by Linnaeus in 1753. The Greek ending "oides" indicates "resemblance" and "tremuloides" means "resembling the species Populus tremula". "Trem" is Latin for "trembling", used here to describe the quivering motion of both these species in the slightest breeze.
