Salix cinerea
Salix gooddingii
The Ohio occurrence of Salix cinerea is based on information from T. Cooperrider (pers. comm.).
Salix cinerea and S. atrocinerea are very closely related. Their occurrence in the flora area, as naturalized introductions, is not well understood, probably because they usually are introduced under the name S. caprea, and that species often is not treated in North American floristic literature (e.g., C. K. Schneider 1921; M. L. Fernald 1950). They probably are introductions of long-standing brought to the New World for their value as ornamentals and bee-plants. Salix atrocinerea was first documented in the southeastern United States (G. W. Argus 1986) after plants with ferruginous hairs and prominently striate wood were found in North Carolina; since that time, it has been found in other states and provinces. In the northeastern states, S. atrocinerea and S. cinerea are thought to be invasive species. The species do reproduce by seed and hundreds of seedlings were observed in a drained reservoir (A. Zinovjev, pers. comm.) and on sandy pond shores (T. Rawinski, pers. comm.), where they are thought to compete with native species.
The presence of long, prominent, striae on the peeled wood of 4–5 year old branches is commonly used in European literature (K. H. Rechinger 1993; A. K. Skvortsov 1999) to separate Salix cinerea and S. atrocinerea from S. caprea etc., in which the wood is smooth or with fewer, shorter striae. In the flora area, long striae also occur in S. bebbiana, S. discolor, and S. humilis, but usually they are not as long as or as prominent in S. cinerea and S. atrocinerea. Some floras (e.g., F. Martini and P. Paiero 1988) use the relative prominence of striae to separate S. cinerea and S. atrocinerea, but their separation remains difficult. The presence of ferruginous hairs on the leaves of S. atrocinerea is the best diagnostic characteristic, but they are not always present or easily observed. For a comparison of these species, see the key to species under subg. Vetrix. For further discussion of morphologies, see Salix ×smithiana Willdenow [p. 132] and 76. S. discolor.

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.
