 sand-hills between the Flint and Chattahoochee, Jackson (Ell.), Baldwin. 

 C. f alcata, Ell. Low, seldom a foot high, branched from the base, very leafy to the top, 

 loosel_y lanate, at length glabrate, not glandular : leaves from narrowly to oblong-linear, 

 obscurely few-nerved, rigid (1 to 3 inches long) ; the cauline spreading and sometimes 

 falcate-recurving : heads mostly numerous and cymose, small : involucre campanulate (3 or

* * Leaves not nervose or gramineous: involuci'e hemispherical: akenes turbiiiate-obovate and 



turgid-flattitli (or in the last species more oblong), 3-5-nerved: outer pappus squaniellate or 



setidose. 

 -K Pubescence arachnoid-lanate or cottony-villous and flocculent, deciduous, leaving a glabrous or 



minutely scabrous and glandulai" surface, sometimes glabrate from the first except on rosulate 



tufts of radical leaves ; Atlantic species. 

 -H- Heads comparatively small, seldom half-incli high, commonly cj'mose: arachnoid hairs sparse 



or wanting: stems very leafy: root no more tiian biennial. 



C. scabrella, Tokr. & Gkay. Glandular-scabrous even to the rather obtuse bracts of the 

 involucre, destitute of cobwebby hairs, stem rather stout: leaves oblong-lanceolate or 



' spatnlate : outer pap2:)us setiform. — Fl. ii. 255. — Pine woods, Tampa, Florida, Leavenworth^

 times broadly spatnlate (barely inch long) radical leaves floccose-wooUy when young: stem 

 slender, virgate, 2 or 3 feet high, very leafy with spatulate-linear to almost filiform (inch or 

 so long) glabrous leaves : heads often numerous and cymose : otherwise as the preceding. —

 denticulations, oblong, or the lower spatulate or obovate and uppermost lanceolate. 



C. Mariana, Nutt. A foot or two high from a perennial root, loosely silky-villous with 

 arachnoid hairs, glabrate iu age : leaves thinnish, green : heads several in a corymbiform 

 cluster: involucre glabrous but granulate-glandular. — Gen. 1. c. (under Inula); Torr. &

_ terminating pedunculiform branches or loosely cia-ymbose: involucre verv woolly, or be-
