10. E. altissimum (Linn.) : stem stout, tomentose-pubescent, corymbosely 

 branched at the summit ; leaves opposite, nearly sessile, lanceolate, some- 

 what tapering to each end, conspicuously 3-nerved, pubescent, acutely and 

 rather remotely serrate above the middle ; the uppermost often entire, and 

 sometimes alternate ; corymbs numerous ; heads glomerate, 5-flowered ; 

 scales of the involucre about 10, linear-oblong, obtuse, pubescent or tomentose 

 and glandular, imbricated, shorter than the flowers; achenia obscurely 

 angled, somewhat glandular. — Linn. ! spec. 2. p. 837 ; Jacq. hort. Vinclob.

Sandy and barren fields, Pennsylvania and New Jersey ! to Florida ! and 

 Louisiana! Aug.-Oct. — Stem about 2 feet high, varying, as also the leaves, 

 from minutely pubescent to hirsute-vilious. Leaves either narrowly or very 

 broadly lanceolate, often very deeply serrate; the veins reticulated beneath. 

 Involucre, corolla, and achenia, when old, copiously sprinkled with resinous 

 globules; in which state it is the E. glandulosum, iVf?'c/i.T. Lobes of the 

 corolla ovate-lanceolate. Style more commonly included, but sometimes 

 manifestly exserted. Pappus densely barbellale-serrulate.

 summit; leaves opposite (the uppermost very frequently alternate), sessile, 

 ovate-oblong and ovate-lanceolate, obtuse or truncate at the base, slightly 

 iripli-nerved, veiny, somewhat pubescent and scabrous, obscurely punctate, 

 coarsely serrate-toothed particularly towards the base ; the uppermost nearly 

 entire ; branches of the corymb few, often alternate ; heads glomerate, 5-
