84 COMPOSITiE. Eupatorium. 



the heads not larger than in E. coronopifolium. Corolla infundibuliform, 

 attenuate below, and abruptly dilated at the base; the teeth very short, ovate, 

 glandular externally. Pappus as long as the corolla. Achenia dotted with 

 scattered resinous globules. — Our plant appears to be that of Elliott, although 

 we have never seen the lower verticillate leaves, and the heads are mostly 

 7-9-flowered. The styles also in our specimens are often all included within 

 the corolla at every stage, and with short very obtuse lobes. Two or three 

 flowers of each head, however, often present the branches of the style elon- 

 gated and much exserted, as described by Elliott. The same thing occurs in 

 several of the succeeding species, and in Kuhnia eupatorioides. where the 

 style is usually included until a late period. 



6. E. hyssopifolium (Linn.) : stem minutely pubescent, simple or branched, 

 loosely corymbose at the summit ; leaves opposite or verticillate, and often 

 fascicled in the axils, the uppermost alternate, linear or lanceolate, rather 

 obtuse, tapering or acute at the base, minutely pubescent, punctate on 

 both sides, 3-nerved, the upper ones 1-nerved, entire, the lower ones spar- 

 ingly toothed or serrate; heads 5-flowered; scales of the involucre 10, shorter 

 than the flowers, very pubescent, glandular; the outer ones short; the others 

 linear-oblong, obtuse, with slightly scarious margins; achenia glabrous and 

 usually glandular.— Z,m«. .' spec. 2. p. 836 (pi. Dill. Eltlu S^-Pluk..' t. 88,

 y. Southern States ! d. " Knobs among the barrens near the Mammoth 

 Cave, Kentucky," Dr. Short! — Stem 1-3 feet high, usually very leafy. 

 Leaves commonly 1 i-2 inches long, rather thick and rigid ; the lateral nerves 

 somewhat anastomozing, approximate to the mid-nerve in the narrower 

 leaves, nearly wanting in the narrowest. Com])ound corj'mb rather loose, 

 often fastigiate. Corolla dilated at the base, as in numerous species, cyathi- 

 form or campanulate at the summit; the lobes ovate, very short. Style 

 usually much exserted. — The Linnfean species was founded on the narrower- 

 leaved plant (E. linearifolium, DC), in which the lower leaves are always 

 3-nerved, and often toothed ; this passes insensibly into our var. y., the ex- 

 treme forms of which appear abundantly different, but Michaux has justly 

 united them. Our two varieties /3. & 6. taken by themselves, would never 

 be thought the same species, but we are unable to separate them. 



7. E. leucolepis: stem mostly simple, puberulent; leaves opposite, divari- 

 cate, lanceolate or linear, obtuse, closely sessile, serrate, very scabrous on 

 both sides, punctate, strongly 1-nerved ; the lower ones obscurely 3-nerved 

 or somewhat veiny ; coryml) fastigiate, canescent ; heads 5-flowered ; scales 

 of the involucre 8-10, lanceolate, acute or acuminate, very pubescent and 

 glandular on the back, white and scarious at the summit, as long as the 

 flowers; achenia minutely glandular. — E. glaucescens /i. leucolepis, DC!
