|discussion=<p>The name <i>Salix taxifolia</i> is used here in the sense of G. W. Argus and C. L. McJannet (1992). R. D. Dorn (1998) used that name instead for what Argus and McJannet called S. microphylla, and for the present species used S. exilifolia. Dorn did not cite specimens of S. exilifolia, but Texas plants, possibly annotated by him, were mapped by B. L. Turner et al. (2003). The distribution of <i>S. taxifolia</i> parallels that of <i>S. thurberi</i> Rowlee, recognized here and by Dorn as a distinct species.</p>
