5. S. latifolia, L. Stem smooth, simple; leaves oval or ovate, acumi- 

 nate, unequally toothed-serrate, mostly pubescent beneath ; racemes roundish

 l-2 high. Leaves 3' -5' long, 2' -3' wide. 



6. S. C86Sia, L. Stem slender, often branching, smooth and glaucous ;

 Racemes in all the upper axils. 



". S. Curtisii, Torr. & Gray. Smoothish ; stem tall, not glaucous, 

 straight and mostly simple, striate-angled ; leaves lanceolate or obovate-lanceo- 

 late, acuminate at each end, sharply serrate above the middle, sessile ; racemes 

 dense, much shorter than the leaves ; heads 8 - 12-flowered ; rays 4 - 6 ; scales 

 of the involucre oblong-linear, obtuse ; achenia hoary -pubescent. Mountains 

 of North Carolina and Tennessee. Sept. Stem 2 -3 high. Leaves 5'-G' 

 long. 



8. S. monticola, Torr. & Gray. Smoothish ; stem terete, simple and 

 slender, puberulent above; leaves very thin, oblong-lanceolate, acuminate, 

 slightly serrate; the upper ones small and bract-like; racemes sessile, the 

 uppermost approximate and nearly as long as the leaves; heads about 15- 

 flowered ; scales of the involucre linear, acute ; acheuia smooth. Mountains 

 of North Carolina. Sept. Leaves and flowers smaller than the last. 



9. S. lancif olia, Torr. & Gray. Smooth ; stem tall, simple, angled ; 

 leaves long-lanceolate, acuminate, finely serrate, sessile ; racemes approxi
