TAXONOMY :
The scientific name of quaking aspen is Populus tremuloides Michx.
(Salicaceae) [60,64,75,78,82,79,165,166]. There are no currently
recognized subspecies or varieties [64,75,78,100,136,165,166]. Roland
and Smith [136] recognize a form with extremely broad leaves, P.
tremuloides forma reniformis Tidestr., that occurs in northeastern North
America.
Quaking aspen is in subsection Trepidae of the genus Populus. Some
authorities consider the Trepidae aspens a single taxonomic entity.
Under this treatment, quaking aspen, bigtooth aspen (P. grandidentata),
European aspen (P. tremula), and three aspens occurring in Asia are
classed together as a single, circumglobal superspecies [126].
Quaking aspen hybridizes naturally with bigtooth aspen and white poplar
(P. alba), a naturalized European species. Hybrid quaking
aspen-bigtooth aspen swarms occur in the Niobrara River valley of
Wyoming and Nebraska [64], and quaking aspen-bigtooth aspen hybrids are
common in some eastern locales [73]. Black cottonwood (P. trichocarpa)-
quaking aspen hybrids occur rarely in Alaska [82].
Quaking aspen has been crossed with several Populus species,
particularly the Eurasian species gray poplar (P. canescens), European
aspen, and white poplar, in tree breeding programs [88].
