Family SalicaceaeEdit

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

Subfamily SalicoideaeEdit

PopulusEdit

Populus sect. PopulusEdit
 
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.

SalixEdit

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 Argus (1999)[1] and Flora of North America,[2] and Lauron-Moreau et al. (2015).[3]

Morphological relationships between the North American Salix subgenera (Argus, 1997), shown here with sections represented in New York State:

Genus Salix




subg. Protitea (NY sect. Humboldtianae)



subg. Salix (NY sects. Salicaster, Salix, Subalbae)




subg. Chosenia (no NY species)




subg. Longifoliae (Single NY species Salix interior)





subg. Chamaetia (NY sects. Herbella, Myrtilloides, Myrtosalix)



subg. Vetrix (NY sects. Candidae, Cordatae, Geyerianae, Griseae, Fulvae, Hastatae, Helix)





Salix subg. ProtiteaEdit
Salix subg. Protitea sect. HumboldtianaeEdit
 
Salix nigra

Salix subg. Protitea sect. Humboldtianae includes the six North American willow species: S. amigdaloides, S. bonplandiana, S. caroliniana, S. gooddingii, S. laevigata, and S. nigra.[1] Of these, S. nigra (black willow) and S. amygdaloides (peach-leaved willow) grow in New York.

Salix subg. Salix sect. Salicaster contains about nine species worldwide with four of those (S. lasiandra, S. lucida, S. pentandra, and S. serissima) found in North America.[1] Of those, S. lucida (shining willow) and S. serissima (Autumn willow) are native to New York. 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]

Salix interior
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.

Willows of subgenus Longifoliae are generally clonal by root suckers with multiple upright stems.

It is found in alpine meadows on the high peaks of the Adirondacks in Essex County, and it is considered to be threatened.

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

It should be noted that although Salix cordataMuhl. 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. cordataMuhl. (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. HelixEdit
 
Salix purpurea
The Salix purpurea cultivar 'Streamco' was released in 1976, in cooperation with the New York State Department of Environmental Conservation. It was selected because of its resilience and superior performance in streambank stabilization practices.[1] This species is also being tracked for its potentially invasive tendencies.
