Coreopsis. COMPOSITE. 293 



C. pubescens, ELL. Taller, 1 to 4 feet high, more leafy, from pubescent to nearlv gla- 

 brous : leaves thickish, oblong, or the lower oval-obovate ami the upper oblong-lanceolate, 

 ofteu all entire, some not rarely with 2 or even 4 small lanceolate lateral lobes or divisions ': 

 heads usually smaller than in the preceding: akeiies similar. Sk. ii. 441; Chapin. Fl.

 in part (7 & 5), and of old gardens. Lcudnn trifoliata, CasS. ? Virginia to S. Illinois, 

 Missouri, and south to Florida. In the middle or low country southward only a slender 

 form, usually with lateral lobes to upper leaves ; in the mountains a larger plant in all its 

 parts, with larger leaves 3 to 5 inches long, 1 or 2 inches wide, all entire, or a few 3-parted, 

 the var. 7, Torr. & Gray, Fl. 1. c. 



4- H Wings of the akene narrow, strongly involute and callous-thickened at maturity. 

 C. auriculata, L. Low and weak, stolon if erous, below commonly villnus-hirsute : stems a 

 foot or so high, including the long and slender peduncle, often simple: leaves of few pairs, 

 ovate to rouud-oval, only an inch or so long, entire and some with a pair of smaller basal 

 lobes, all but the upper sleuder-petioled : head comparatively small : rays little more than 

 half-inch long: akeues by involution of margins oblong and umbilicate. Spec. ii. 908 

 (Pluk. Aim. t. 242, f. 4, and perhaps t. 83, f. 5 ; Moris. Hist. \\\. sect. 6, t. 3, f. 45) ; Michx. Fl. 

 ii. 138; Ell. 1. c. (var. diversi folia) , Torr. & Gray, 1. c., as to typical form, but the akeues 

 were then unknown. C. divers/folia, DC. Prodr. v. 571, excl. syn. Wooded ground, 

 Virginia and Kentucky to the borders of Florida. 



3. EUCOREOPSTS. Style-tips produced into a cusp or acute cone : akenes 

 straight or little incurved, oblong, with narrow wing or none ; no calli on the 

 inner face : rays mostly entire or slightly toothed (yet sometimes 2-3-cleft) at the 

 apex, pure yellow: disk-corollas yellow (sometimes dull, rarely turning brown) : 

 leaves opposite, in some seemingly verticiHate. Torr. & Gray, FL, excl. Leachia. 



* Perennials, mostly low (a foot or two higli\ leafy to the summit: leaves sessile, palmately 

 divided or cleft, but never serrate, not veiny: involucre becoming rigid, its bracts all united 

 at the base; outer oblong-linear, erect, about the length of the inner: rays from oblong to 

 lanceolate : chaff of the receptacle linear-filiform and persistent: akenes oblong, narrowly wing- 

 margined: pappus 2-toothed or 2-aristellate, or obsolete: stems and branches striale-angled 

 when dry. Gyropliyllum, Nutt. 



4 Leaves 3-cleft to or below the middle, but not to the base, which has a 3-nerved midrib. 



C. palmata, NUTT. Glabrous, rigid : stem nearly simple : leaves cuneiform in outline ; the 

 undivided basal portion little wider than the rather broadly linear lobes, which are either 

 simple or again 1-3-lobed, the margins scabrous : rays obovate-obloug akenes oblong.

-j -i Leaves divided to the base, the pair thus imitating a whorl of six, or the uppermost simple, 

 rarely some of the lower also simple. 



C. verticillata, L Glabrous, slender : leaves 2-3-ternately dissected into very narrowly 

 linear or nearly filiform lobes . heads small : rays narrowly oblong . disk-corollas dull yellow : 

 akenes obovate-cuneiform. Spec. ii. 907; Lam. Diet. ii. 108; Michx 1. c. (var. tenuifu/ni) ;

C. delphinifolia, LAM. Stouter than the preceding: divisions of the leaves fewer and 

 wider; the middle one once or its midlobe again 3-parted, lateral ones 2-parteJ or simple ; 

 lobes all linear, 2 lines wide: disk-flowers brown! Diet. ii. 108; DC. 1. c. , Torr. & Gray,
