From Flora Novae Angliae dichotomous key
30. Salix viminalis L. E
osier willow. CT, MA, ME, NH, RI, VT. River banks, near dwellings.
Salix babylonica L. ×Salix euxina I.V. Belyaeva. Salix ×pendulina Wenderoth is an uncommon willow hybrid in New England known from CT, MA, ME. It is very similar to 1a ×S. babylonica ( S. ×sepulcralis), especially in its pendulous branches and branchlets, but has green-brown (or less frequently yellow-brown, gray-brown, or red-brown) branchlets rather than gold-yellow (or less frequently green-yellow) branchlets.
8×30. Salix caprea × Salix viminalis → Salix ×sericans Tausch ex Kern. is a rare willow hybrid in New England known from MA, ME. It is sometimes referred to by the name S. ×smithiana Willd. (9 ×30), but that name properly refers to the hybrid betweenS. cinerea and S. viminalis (a hybrid that has not been documented in New England). It has lanceolate to broad-lanceolate leaf blades that are mostly 13–30 mm wide (vs. oblong to suborbicular and 25–80 mm wide in S. caprea and narrow-lanceolate to narrow-elliptic and 5–15 (–25) mm wide in S. viminalis). This hybrid is further characterized by dense gray tomentum on the abaxial blade surface, precocious flowering, and dark floral bracts that are densely pubescent.
Native to North America?
No
Sometimes confused with
- Salix elaeagnos:
- leaf blades elongate-linear, 1–8 mm wide, mostly 17–40 times as long as wide (vs. S. viminalis, with leaf blades narrow-lanceolate or narrow-oblong to oblanceolate or obovate, 7–30 mm wide, mostly 4.7–13.7 times as long as wide).
- Salix pellita:
- branchlets brittle at base, breaking +/- cleanly at the junction of yearly growth, becoming glaucous later in season, aments precious, and adaxial nectaries 0.25–1 mm long, shorter than to longer than the stipe (vs. S. viminalis, with branchlets flexible at base, tearing when bent to failure, not glaucous, aments mostly coetaneous, and adaxial nectaries 0.9–1.4 mm long, longer than the stipe).
