S. NIGRA Marsh. Material referable to var. falcata (Pursh) Torr., 
as at present understood, was collected at Burlington and Williston; 
but from many observations in Vermont and Massachusetts I have 
become convinced that this so-called variety represents merely the 
normal condition of young branchlets in this species. The leaves on 
older wood and at base of first year shoots are oblong and straight, 
those at tips of young shoots much narrower and scythe-shaped. 
S. PEDICELLARIS Pursh var. HYPOGLAUCA Fernald. South end of 
Porters Swamp, Colchester. Mrs. Flynn, following the Manual 
strictly, gives S. pedicellaris only, but the only form known ! in the 
Burlington Region is var. hypoglauca Fernald.
