Discussion

Hybrids:

Salix uva-ursi forms natural hybrids with S. herbacea.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Salix gooddingii and S. nigra are closely related and are sometimes treated as conspecific (C. R. Ball 1950). Salix gooddingii has yellow-brown or pale gray-brown branches, capsules 6–7 mm, and ovaries usually glabrous but pilose in ca. 20% of specimens. Salix nigra has red-brown to dark gray-brown branches, capsules 3–5 mm, and ovaries almost always glabrous. A single plant with pilose ovaries was found in Ontario, Canada; reports (W. A. Archer 1965) of S. nigra with hairy ovaries in Alabama, Arkansas, Illinois, Iowa, Kansas, Massachusetts, Oklahoma, and Texas could not be confirmed. Ranges of these taxa overlap in west-central Texas, where there is evidence of intergradation; they rarely occur in the same population. The map by E. L. Little Jr. (1971), who treated them as conspecific, shows a significant range disjunction between the two.

Catkins of Salix gooddingii flowering in March and early April are sometimes borne in leaf axils. This suggests that the sylleptic condition, typical of S. bonplandiana, is sometimes ecotypic.

Hybrids:

Salix gooddingii forms natural hybrids with S. amygdaloides and S. nigra. Hybrids with S. lasiandra have been reported (C. K. Schneider 1921); no convincing specimens have been seen.

Salix gooddingii × S. laevigata: In Arizona, a population of young plants displays intermediate characteristics. They have leaf blades sparsely glaucous abaxially, as in S. laevigata, but narrow, often amphistomatous, and with petioles sometimes not glandular distally, as in S. gooddingii. Both parental species occur in the region. This hybrid was also reported by C. K. Schneider (1921) from California.

Salix gooddingii × S. nigra: This hybrid may occur in western Texas where the parental species overlap. Some specimens from that area seem to be “intermediate” in branch color, but the differences are subtle.
