Abies balsamea (Linnaeus) P. Miller. Common name: Balsam Fir, Northern Balsam, Blister Pine, Fir Pine. Phenology: Apr-May. Habitat: High elevation forests and cliffs (in VA and northwards); high elevation frost-pocket wetlands (WV), northwards somewhat more general in cool, mountain areas. Distribution: NL (Newfoundland) and NL (Labrador) west to n. AB, south to NY, PA, MI, WI, and IA, and (disjunct) in the mountains to n. VA and e. WV.

Origin/Endemic status: Native

Taxonomy Comments: There has been considerable debate over the taxonomic status of some populations of A. balsamea, which show some intermediacy of characters toward A. fraseri, and have been variously treated as A. intermedia Fulling, A. balsamea var. phanerolepis Fernald, or A. ×phanerolepis (Fernald) Liu. Variation in e. North American Abies is somewhat clinal, with the greatest geographical and morphological discontinuity between n. VA and s. VA. It seems best, therefore, to recognize A. fraseri as a species and A. balsamea as a species (which includes the clinal var. phanerolepis).

Other Comments: The balsam woolly adelgid, an alien pest, is afflicting this species in Shenandoah National Park.
