Family Salicaceae

The Salicaceae (willow family) in New York contains the two tree genera Populus (aspens, cottonwoods, and poplars) and Salix (willows).

    Subfamily Salicoideae

    Populus

    Populus sect. Populus
    Populus tremuloides & grandidentata
    Section Populus contains the two North American trees quaking aspen (P. tremuloides) and bigtooth aspen (P. grandidentata). The section also contains several Eurasian species, including P. tremula and P. alba. All of these species are known to hybridize with one another.

            Salix

            The genus Salix contains the trees and shrubs known as willows, of which about 36 native or naturalized taxa have been discovered in New York. The organization used here is based in part on George W. Argus (1999) "Classification of Salix in the New World" and Flora of North America, Vol. 7, Salicaceae.

              Salix subg. Longifoliae
              The North American willows in Salix subg. Longifoliae are S. columbiana, S. exigua, S. interior, S. melanopsis, S. sessilifolia, S. taxifolia, and S. thurberi. Only S. interior is currently listed as being part of the New York flora.

              The New York Flora Atlas follows Flora of North America in treating the native sandbar willow, S. interior as a separate species from S. exigua, and not just a subspecies.

                      Salix subg. Vetrix sect. Cordatae
                      Salix eriocephala Michx.
                      Salix sect. Cordatae [1] contains about 7 North American species,[2] one of which (Salix eriocephala Michx.) is known to be native to New York.

                      It should be noted that although Salix cordata Muhl. is now considered to be an illegitimate synonym of S. eriocephala, Salix cordata Michx. is the accepted name for "sand dune willow" in Salix subg. Vetrix sect. Hastatae, which is also native to New York. Both of these species have understandably been referred to by the common name "heart-leaved willow," but Leonora Goodrich, describing S. cordata Muhl. (non Michx.) in her 1912 Flora of Onondaga County, notes: "Base of leaves so slightly cordate it hardly warrants the name."[3]

                                Salix subg. Vetrix sect. Phylicifoliae contains about eleven species globally and the following five willows in North America: S. drummondiana, S. pellita, S. planifolia, S. pulchra, and S. tyrrellii. None of these are known to be found in the wild in New York, although S. pellita has in the past been listed as part of the New York flora.

Reports of the Eurasian S. pentandra (laurel willow) in New York are now considered to be S.×meyeriana (S. euxina × S. pentandra), Meyer's willow.[2]
