 the upper entire. — Var. 2. scAi!Kiii,i,.\ is .somewhat roughish-])ubeseent (Wis- 

 consin, &c.). — Copses and banks : common, especially the first variety. — Well 

 distinguished by its long or droo])ing racemes, and the closely appressed rigid 

 scales of the involucre, siii;ill rays, i*^c,. But the name is a bad one, as eveu 

 the root-leaves are seldom much tootlied. 



21. S. Muhlenb6l'gii, Torr. & tJr. Smooth; stem am/led; leaves (large 

 and thin) orate, ami the upper elliptical-lanceolate, very sharply and strongly ser-

24. S. Ulmifblia, Muhl. Stem smooth, the branches hairy; leaves thin,
