 the summit ; heads (large) in a dense thyrsoid or corymbose raceme ; scales 

 of the involucre narrow, nearly glabrous; rays 8-12; leaves ciliate, oblong-

 this country is confined to the Nortliern regions, and the higher mountains 

 of the Northern States. Nearly all the American specimens belong either 

 to var. /3., which very nearly approaches the var. Cambrica of Europe, or 

 to the var. y., which passes insensibly into other forms of this species, to 

 •which it should doubtless be united. 



25. S. thyrsoidea (E. Meyer) : stem erect or somewhat flexuous, simple, 

 very glabrous, the summit and peduncles viUous-pubescent ; leaves glabrous, 

 ovate, irregularly and sharply serrate, acute or acuminate, veiny, all except 

 the upper cauline abruptly narrowed into very long petioles; the ujjpermost 

 oblong-lanceolate, subsessile, often pubescent beneath ; raceme oblong, sim- 

 ple or slightly compound; heads large; the peduncles mostly ebracteate ; 

 scales of the involucre nearly equal, lanceolate, acuminate, membranaceous, 

 nearly glabrous; rays 8-10; achenia glabrous (slightly pubescent at the 

 summit). — E. Meyer, j^l- Lahrad. p. 63; DC. pirodr. 7. {mant.) p. 279.

 Sept. — Allied to S. Virga-Aurea (var. alpestris) ; but certainly a distinct 

 species; remarkable for the abrupt and very long petioles of all but the up- 

 permost cauUne leaves (frequently two to three inches long, supporting a 

 lamina about half that length, and an inch or more in breadth) ; for its larger 

 heads, which perhaps are only exceeded by the following; and the glabrous 

 achenia, upon which, however, a little hairiness is observable near the sum- 

 mit. The raceme commonly consists of 6 to 12 heads, on short and simple 

 bractless peduncles from the axils of the upper leaves, &c., rather crowded : 

 but one specimen from Labrador presents a large raceme more than 6 inches 

 long, with nearly all the peduncles somewhat elongated and bearing 2 to 4 

 heads ; the pedicels often longer than the heads, and furnished with a linear- 

 subulate, scarious, deciduous'bracteole. Rays rather short.— The species is 

 well described by Meyer.
