Populus balsamifera Linnaeus. Balsam Poplar, Hackmatack, Tacamahac. Phen: Mar-Jun; May-Jul. Hab: Floodplains, disturbed areas. Occurring further north in a variety of habitats such as depressions, drainages, river bottoms, spruce-aspen forests, or on well-drained sites atop glacial deposits. Dist: NL (Labrador) and AK south to PA, WV, OH, IN, IL, IA, SD, CO, ID, and OR; scattered farther south by introduction. Ranges south to s. PA (Rhoads & Block 2007), e. and c. KY (Clark et al. 2005), and to VA (according to Kartesz 1999). Also reported for n. GA (Jones & Coile 1988) and provisionally for SC (Kartesz 1999), but apparently based on a specimen from cultivation. Many of the attributions of this species to states in our area are based on misidentifications.
