Summary Three taxa of the genus Abies occur in Eastern North America: A. balsamea (L.) Mill. var. balsamea, A. balsamea (L.) Mill. var. phanerolepis Fern., and A. fraseri (Pursh) Poir. The occurrence of “intermediate” populations in the Mid‐Appalachians has resulted in a confused literature concerning the delimitation and distribution of these taxa. Data obtained from serological and electrophoretic investigation of seed protein are presented which support results of independent studies by Myers and Bormann (1963) and Robinson and Thor (1969). These data indicate that A. b . var. balsamea and A. fraseri are closely related and recently segregated taxa and that A. b . var. phanerolepis is more closely related to A. b . var. balsamea than to A. fraseri and is not of hybrid origin.
