A. gracilis, DC. 1. c. Sometimes slender and strict, not rarely more robust than the pre- 

 ctdins:, often some bristly hairs on the stem and lower leaves ; peduncles usually glandular- 

 hispid some way below the head ; this commonly 3 lines high in fruit : corollas orange, con-

 apex, .sometimes an obscure vestige of pappus! — .1. kumi/is, ^att. Trans. Am, Phil. Soe.l. c.,

 (over half-line long), little contracted at either end, and with comparatively large areola 

 (yet les^ than the full breadth of the akene), this bordered by obscure ve.-tige of pappus.

 least toward the summit : leaves obovate to lanceolate, entire, lyrately lobed or pinnatifid : 

 heads 2 or 3 lines high : akenes transversely rugulo^^e : palese of the papjjus cons|jicnous, 

 ronnded-obovate ; ljristle.s or rather aivns alternating with these and over the stronger angles 

 of the akene sometimes equalling it in length, sometimes not surpassing the palese, some- 

 times (var. miiticM, Torr. & Gray) obsolete or wanting. — .Jour. Acad. Philad. vii. 104, &
