C. graminifolia : akenes the same. — Sk. ii. 335. Pityopsis pinifolia, Nutt. 1. c. — Georgia, on 

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

 C. falcata, Eli>. Low, seldom a foot high, branched from the base, very leafy to the top, 

 loosely 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 

 4 lines long). — Sk. ii. 336 (note) ; DC. 1. c. ; Torr. Fl. N. Y. i. t. 56. Inula falcata, Pursh, 

 Fl. ii. 532. Pityopsis falcata, Nutt. Trans. Am. Phil. Soc. 1. c. — Barren land along the coast, 

 Cape Cod to New Jersey. 



# # Leaves not nervose or gramineous: involucre hemispherical: akenes turbinate-oborate and 



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



setulose. 

 -1— Pubescence arachnoid-lanate or cottony-vi'llous and flocculent, deciduous, leaving a glabrous or 



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



tufts of radical leaves : Atlantic species. 

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



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



C. scabrella, Torr. & Gray. Glandular-scabrous even to the rather obtuse bracts of the 

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

 spatulate: outer pappus setiform. — Fl. ii. 255. — Pine woods, Tampa, Florida, Leavenworth, 

 Garber. Too near the broad-leaved form of the next. 



C. trichophylla, Nutt. Villous when young with very long and soft usually scattered 

 hairs which mostly have a stouter base : stem slender, 1 to 3 feet high : leaves oblong-spatu- 

 late or oblanceolate and obtuse, or upper, linear : bracts of the involucre smooth, acute : 

 outer pappus squamellate-setulose. — Gen. ii. 150; Torr. & Gray, 1. c. Diplopappus tricho- 

 phyllus, Hook. Comp. Bot. Mag. i. 97. — Dry ground, N. Carolina to Florida and Louisiana, 

 in the low country, chiefly on and near the coast. Broad-leaved form approaches 

 C. Mariana : narrower comes too near the next. 



C. hyssopif olia, Nutt. Glabrate and smooth, but the rosulate linear-spatulate or some- 

 times broadly spatulate (barely inch long) radical leaves floccose- woolly 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. — 

 Jour. Acad. Philad. vii. 67. C. trichophylla, var. hyssopifolia, Torr. & Gray, Fl. ii. 254, excl. 

 syn. Hook. — Sand-hills and dry pine barrens of Florida, on the coast. 



++ -H- Heads larger: wool floccose: akenes often with 2 to 4 salient and glandular-thickened 

 nerves or vibs : outer pappus more squamellate : leaves occasionally with a few serratures or 

 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 in age : leaves thinnish, green : heads several in a corymbiform 

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

 Gray, 1. c. ; Bertol. Misc. vii. t. 2. Inula Mariana, L. Spec. ed. 2, ii. 1240. Aster Caro- 

 linianus pilosus, etc., Mill. Ic. t. 57. Diplopappus Marianus, Hook. 1. c. — Pine barrens and 

 sandy soil, coast of New York to Florida and Louisiana. 



C. gossypina, Nutt. 1. c. A foot or two high from a biennial root, densely lanate, the wool 

 becoming tomentose-floccose : leaves all obtuse, mostly short and spatulate or oblong : heads 

 terminating pedunculiform branches or loosely corymbose : involucre very woolly, or be- 

 coming glabrate or even glandular. — Torr. & Gray, 1. c. ; Bertol. Misc. vii. t. 1. Inula 

 gossypina, Michx. Fl. ii. 122. I. glandulosa, Lam. Diet. iii. 259 1 Erigeron pilosum, Walt. 

 Car. 206. Chrysopsis dentata, Ell. Sk. ii. 337, a form with lower leaves few-toothed. C. de- 

 cumbens, Chapm. Fl. 217, a coast form with glandular peduncles and involucre. — Sandy pine 

 barrens, N. Carolina to Florida and Alabama, in the low country. 



-H- -I— Pubescence from hispid to silky-villous, persistent: root perennial. Includes a multitude 

 of forms, seemingly not distinguishable into species. . 



C. villosa, Nutt. 1. c. A foot or two high : leaves from oblong to lanceolate, rarely few- 

 toothed, usually cinereous or canescently strigose or hirsute and sparsely hispid along the 

 margins and midrib, an inch or two long : heads mostly terminating leafy branches some- 

 times rather clustered, naked at base or foliose-bracteate : involucre campanulate, 4 or 5
