pie, lanceolate, serrate ; raceme simple, of axillary clusters, the uppermost 

 capitate, crowded ; involucre turgid, many-flowered. Michx. fl. 2. p. 117. 



Mountains of Carolina, Michaux. — With much hesitation we join to this 

 species a remarkable plant which we had called 5'. macra?itha, collected in 

 flower on the Roan Mountain by Mr. Curtis, and which is also abundant 

 towards the summit of the Grandfather, N. Carolina (Gra?/, in Sill.journ. 42. 

 p. 35) ; flowering in August. It is one to 2 feet high, with a stout striate- 

 angular glabrous stem; with large, broadly lanceolate or obovate-lanceolate, 

 glabrous leaves, 4-9 inches long, the lower 2-3 broad, ciliate especially to- 

 wards the tapering entire base, serrate above with small sharp teeth, acumi- 

 nate, veiny, of afirm but rather thin texture; the radical tapering into a 

 winged petiole. Heads larger than those of S. rigida, 3-7 together in short 

 racemes or clusters in the axils of the upper leaves, at first glomerate, but 

 when expanded the pedicels (stout and pubescent, like the peduncles) are 

 often as long as tlie heads ; the lowest clusters somewhat remote, the others 

 approximate, forming a narrow (sometimes thyrsoid) elongated panicle or 

 compound raceme, mostly simple at the sumtnit. Scales of the involucre 

 imbricated in 3 or 4 series, 1-nerved, acutish ; the exterior oblong-ovate, the 

 innermost linear-lanceolate, nearly glabrous, flowers 30-40 in each head ; 

 the rays 10-12, small in proportion. Achenia pubescent towards the sum- 

 mit, nearly a;labrous below. — We know not what plant Nuttall had in view 

 as the S. glomerata, of which he remarks {Gen. 2. p. 161) : " Lower leaves 

 broad oval and acuminate, serrate : nearly allied to Aster." Nor have we 

 been able to ascertain the species mentioned by Schweinitz (in EU. sk. 2. 

 p. 387,) as " distinguished by its deep and close serratures, and the capitate 

 form of the axillary racemes" : the latter, however, is probably S. latifblia. 



* * * Heads in a compomid corymb tenninating the simple stem, showy: Uaves feather- 

 veined or 3-nerved. — Corymbosse. 



t Scales of the involucre acute : achenia pubescent : leaves veiny. 



27. S. spilhameea (M.A.Curtis! mss.) : stem villous-pubescent, leafy; 

 leaves oval or oblong-lanceolate, ciliate, nearly glabrous, sharply serrate 

 above the middle, or the uppermost entire ; the lowest and radical spatulate- 

 oblong, tapering into winged petioles; heads (middle-sized) disposed in a 

 compound glomerate corymb; peduncles and pedicels villous ; scales of the 

 involucre somewhat eijual, lanceolate, ciliate ; rays 6 or 7, short ; achenia 

 pubescent. — Gray ! in Sill. jour. 42. j)- 42. 



Rocky places on the bald summit of the Roan Mountain, North Carolina 

 (at an elevation of 6000 feet) ; where it was discovered, in 1835, by Mr. 

 Curtis! Aug.-Sept. — Stems 8-10 inches high, growing in tufts from a 

 branching caudex. Leaves membranaceous, 1-3 inches long, rarely an inch 

 in width, irregularly and sometimes incisely serrate ; the uppermost acute; 

 the lower conspicuously ciliate along the entire narrowed base. Heads 25- 

 30-flowered. Scales of the somewhat hemispherical involucre appressed, 

 1-nerved, slightly carinate, with scarious minutely lacerate-ciliate mar- 

 gins, acute or acuminate; the outer broadly, the inner narrowly lanceolate. 

 Rays scarcely exserted. 



+ t Scales of the involucre very obtuse: achenia glabrous : leaves mostly feather- 

 veined from a strong midrib : rays several. 



28. S. rigida [\Axm.): scabrous-pubescent, somewhat hoary ; stem stout; 

 the short compact racemes corymbose at the summit ; leaves rigid ; the 

 lower mostly oval or oblong, serrate, petioled; the others ovate-oblong, 

 closely sessile, slightly clasping ; the uppermost entire ; heads (very large)
