Named from a, not, and seira, a band, because rejected from 



the garlands of the ancients. 241. 



1. A. Europte'um. Common Asarabacca. Leaves two on each 



stem, kidney-shaped, obtuse. Roots creeping: stems very short, 



simple, round, each bearing two leaves, and a single flower, of a

 forms the base of cephalic snuffs. Perennial: flowers in May: 

 grows in mountainous woods in the north of England, but is not a 

 native plant. Eng. Bot. vol. xvi. pi. 1083. Eng. Fl. vol. ii. p. 342. 723.
