The species included in this key are those from the Washington- 
Baltimore flora (Hermann, 1946) which the available literature does 
not report as restricted to the Piedmont. Of these seven species, 
three (S. nigra, S. sericea, and S. tristis) are represented from the 
Maryland Coastal Plain in the U. S. National Herbarium. Only S. nigra 
has been found at the Chesapeake Bay Center to date. This key should 
facilitate the search for additional species there. 
1. Leaves entire or sparingly undulate-crenate, narrowly 
oblanceolate to obovate; plant a shrub. (Also, aments 
preceding the leaves; staminate and pistillate 
flowers each with one basal gland.) Expected (S. 
humilis, S. tristis). 
1. Leaves closely serrulate, linear-lanceolate to 
broadly lanceolate; plant a tree (shrubby in S. 
sericea). (Also, scales of ament pubescent.) 
2. Aments sessile, preceding the leaves; scales 
blackish, persistent; capsules silky-puberulent; 
staminate flowers each with one basal gland. 
(Also, leaves acuminate, glaucous and silky 
beneath; stamens 2.) Expected (S. sericea).
