A putative hybrid between S. atrocinerea (or S. cinerea) and S. discolor. Alternatively, one may place this willow
with S. aegyptiaca, though it is still not known for certain if the latter has been
introduced to eastern Massachusetts. Since both S. discolor and S. atrocinerea complex occur in the immediate proximity, attribution to
S. aegyptiaca is not enough justified. Observations at another season
may help with more precise identification.
