Fig. 266. Small Solomon's Seal, also commonly known as true Solomon's Seal {Poly- 

 gonalum biflorum). It is a perennial herb with lance-oblong, sessile leaves, in the axils of 

 which are usually two nodding greenish flowers. The plant grows in moist woods or wooded 

 hillsides, and receives its common name from the creeping knotted rhizomes, on the upper 

 surface of which are usually one or more prominent circular scars, formed upon the decay 

 of the aerial shoots. — After Biown.
