Dry soil, in rich woods and along streams, Virginia ! and Kentucky ! to 

 Middle Florida! and Western Louisiana! more abundant in the mountain- 

 ous districts. 6. Mountains of North Carolina! May-Sept. — li Like 

 most plants which flower throughout the summer, this species presents many, 

 variations. We have distinguished only the more important, assuming the 

 smaller and vernal form as the type, which is moreover the plant of Plukenet, 

 Clayton, &c. The stoutest and large-leaved var. 6. resembles some of the 

 garden states, which have been long in cultivation. Ripe achenia dark 

 brown. 



14. C. lanceolata (Linn.) : pubescent or nearly glabrous ; stems short, as- 

 cending, often branched near the base ; leaves entire, with ciliate or scabrous 

 margins ; the radical and lower cauline oblanceolate or spatulate-oblong, 

 tapering into hairy petioles; the upper oblong-lanceolate or linear-lanceolate, 

 sessile, "slightly connate at the base (the uppermost rarely alternate) ; heads 

 miostly solitary, on very long naked peduncles ; scales of the exterior involu- 

 cre ovate-lanceolate; rays deeply 4-5-toolhed or incised at the summit; 

 achenia nearly orbicular, incurved when mature, broadly winged, crowned 

 ■with 2 very short auriculiform denticulate squamellaB, which when old be- 

 come (especially in cultivation) subulate teeth. — Linn.! spec. 2. p. 908;

15. C grandi flora (l^uU.) : glabrous; stem slender, striate-angled, simple 

 or branchino; ; leaves on hirsute or somewhat ciliate petioles ; the radical 

 lanceolate or linear-spatulate, or sometimes divided ; the cauline 1-2-pin- 

 nately or ternately 3-5-parted, with the segments or lobes narrowly linear or
