INTRODUCTORY
FEIS ABBREVIATION:POPBALT SYNONYMS:Populus trichocarpa Torr. & Gray [69] Populus balsamifera ssp. trichocarpa (Torr. & Gray) Hult. [73] NRCS PLANT CODE [152]:POTR2 COMMON NAMES:black cottonwood TAXONOMY:The scientific name of black cottonwood is Populus balsamifera L. ssp. trichocarpa (Torr. & Gray) Brayshaw (Salicaceae) [67,77,156]. Balsam poplar (Populus balsamifera ssp. balsamifera) is also classified in the genus and is covered in a separate FEIS summary. Both subspecies are in the Tacamahaca section of the Populus genus [41]. Black cottonwood commonly hybridizes with other members of the Tacamahaca section, such as narrowleaf cottonwood (P. angustifolia) and balsam poplar [41,83]. Balsam poplar × black cottonwood hybrids have been reported in Alaska, British Columbia, and Alberta [28,49,57,73]. Hybrids with members of the Aigeiros section are also observed. Eastern cottonwood (P. deltoides var. occidentalis) × black cottonwood hybrids have been reported near Flathead Lake, Montana [69], and Fremont cottonwood (P. fremontii) × black cottonwood hybrids (P. × parryi Sarg.) [86] grow in California [35]. Black cottonwood has also hybridized with black poplar (P. nigra), a Eurasian species [41]. Intersectional hybridization does not occur beyond the F1 generation in most cases, but this type of introgression probably occurred in the past where the ranges of eastern and western species overlap [41].
