Salix serissima (L. H. Bailey) Fernald
Common Name: AUTUMN WILLOW
Coefficient of Conservatism: 8
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt Shrub

Fens, open cedar and tamarack swamps, shores and streamsides, usually in calcareous sites.

Frequently distinguished in manuals from S. lucida by shorter aments. Although this is a tendency, it is not sufficiently consistent to use as a key character. Mature pistillate aments of Michigan specimens of S. serissima range 2–5 cm long; those of S. lucida 1.5–5 cm long. Staminate aments are ca. 2.5–3.5 cm long in S. serissima and 1.5–6 cm in S. lucida.
