AND GENERA OF PLANTS. 359 



14. Corecypsis palmata; Nutt. Outer sepals linear, about twelve ; rays eight, 

 nearly entire. Achenium oblong, flat, alated ; in an immature state with two 

 minute teeth. A strict congener with the preceding. 15. Coreopsis tripteris, 

 Linn. Chrysostemma tripteris; Lessing. Syn. 227. Degand., Vol. V., p. 567. — 

 Peramibus of Rafinesque is thus far, to me, a nonentity ! 



§. *Eublepharis. — Achenium ohlong-compressed, straight, carinated, rvith a 

 ciliate-serrated callous margin and base, the apex rvith trvo short arvns, scarcely 

 Imiger than the serratures; rays three-lohed, the middle lobe longer. — Leaves al- 

 ternate, entire, linear; corymb unequal,, dichotomal. Probably a genus ? 



16. Coreopsis gladiata; Walter. 



Hab. Georgia and Fayette, North Carolina. Outer involucrum skort; radical leaves spathulate- 

 oblong, obtuse, somewhat fleshy ; cauline narrow linear, remote and few ; flowering branches nearly 

 naked. 



§ * Rabdocaulis. — Achenium linear-oblong, straight, compressed, minutely ciliated 

 on the margin, rvith a pappus of trvo erect, somervhat scabrous bristles. Rays 

 almost equally three-lohed. — heaves entire, opposite and alternate; outer involu- 

 crum small. 



17. Coreopsis angustifolia; Aiton. Leaves alternate, the radical lanceolate, 

 long petiolate, carnose, cauline linear, remote; corymb dichotomous, few- 

 flowered. 



18. Coreopsis linifolia; Nutt. From a specimen collected in Alabama by 

 my friend. Dr. Juet, I find that the lower oblong leaves are alternate and re- 

 mote. The flowers disposed in an irregular corymb; outer involucrum about 

 one-third the length of the inner. Inner sepals ovate-lanceolate, acute, Rays 

 about eight, deeply three-lobed. Achenium linear-oblong, straight, compressed, 

 minutely ciliated on the margin, with a pappus of two erect, long, equal bris- 

 tles. The plant three to four feet high. Stem leaves opposite, linear, about a 

 line wide, one to two inches long, and very remote, so that the stem appears 

 almost like a naked twig. Flower conspicuous, yellow, with a brown disk. 



19. Coreopsis nudata; Nutt. Awns of the achenium pubescent, very short; 

 stigmas obtuse, pubescent at the extremity. The whole plant almost destitute 

 of visible leaves.
