Tribe V. CYNAREE. 
Subtribe CARDUINE. (Lessing.) - 
CARDUUS. (Gertner.) 
§. 1. *Leprocuzta.—Rays of the pappus slender and fen; anthers hisetose at 
base, the sete lacerate. 
Carduus *occidentals; 4, dwarf; leaves deeply pinnatifid, above nearly 
smooth, beneath canescently tomentose, segments subpalmate, ultimate divi- 
sions lanceolate, terminating in short spines, and spinosely serrulate; involu- 
erum subglobose, arachnoidly tomentose; divisions lanceolate, erect, termi- 
nating in stright spines, the innermost scariose, spineless and acuminate. 
Has. Round St. Barbara. Stem tomentose, six inches to a foot high. Leaves four or five 
inches long, about three-quarters to one and a quarter inches wide, with a lanceolate outline, softly 
tomentose beneath, the lower petiolate, cauline amplexicaule at the base, divisions somewhat 
palmate, in three or four unequal segments, the spines short. Capituli two or three, terminal, 
subsessile, pale purple; florets very slender, subringent or unequally cleft. Anthers distinetly 
bisetose and lacerate at base ; pappus scanty, more. slender than in most European Cardui; some- 
what scabrous, the whole habit of the plant similar to that of Circiwm discolor. The pubescence 
of the involucrum quite as remarkable as in the Cob-web Sempervivum, spreading from one scale 
to another in right lines. 
CIRCIUM. ( Tbitrnsteed 
Ozs. To the character of this genus I would add, that in all the species which 
I have examined, indigenous to America and the old world, the anthers are 
very distinctly caudate at base, with this appendage generally torn or cleft 
more or less deeply at the extremity. Erythrolena and Chamepeuce are, 
therefore, mere sections in the present genus, distinguished principally, and 
almost solely, by habit and the form of the involucrum. 
§. 1. Erioeris, (Cass., Decand.) 
~ Circium * Hookerianum,; arachnoidly tomentose; stem nearly simple; radical 
leaves deeply sinuately pinnatifid, beneath canescently tomentose, the segments 
sublanceolate, unequally bifid, spiny at the points, and ciliately spinulose; stem 
leaves narrow lanceolate, slightly decurrent, rigidly spiny, the summit merely 
toothed, with the segments bifid and very short; capituli few, axillary and ter-
