|discussion=<p>The decaploid to dodecaploid chromosome number for <i>Salix maccalliana</i>, highest in the genus, suggests a complex origin. Relationships with subg. Chamaetia and subg. <i>Salix</i> were suggested by Rowlee and by H. M. Raup (1959). Staminate flowers with abaxial nectaries, tawny and persistent bracts, and villous ovaries suggest a link with <i>S. glauca</i>; leaves with coarse, ferruginous hairs and serrate margins suggest <i>S. lucida</i> (Rowlee). Although <i>S. maccalliana</i> is phenetically closer to sect. Salicaster than to (subg. Chamaetia) sect. Glaucae (G. W. Argus 1997), it is probable that because it incorporates genomes from more than one subgenus, its subgeneric placement is arbitrary.</p>
