Notes: FNA2: "Abies grandis is rather uniform morphologically and chemically. At its southern limit in southern Oregon and northern California, it introgresses with A . concolor (J.L. Hamrick and W.J. Libby 1972; E.Zavarin et al. 1975; D.B. Zobel 1973). In the area of introgression, specimens in lower, wetter habitats are best assigned to A . grandis ; those in higher, drier habitats, to A . concolor . Others are best considered to be A . concolor Â´ grandis."
