|discussion=<p><i>Abies grandis</i> is rather uniform morphologically and chemically. At its southern limit in southern Oregon and northern California, it introgresses with <i>A. concolor</i> (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 <i>A. grandis</i>; those in higher, drier habitats, to <i>A. concolor</i>. Others are best considered to be <i>A. concolor</i> × grandis.</p>
