and leaves; tbe latter more veiny (the primary veins evident and often re- 

 ticulated), pale beneath, instead of green both sides, (2-3 inches long, an 

 inch or less in width, the upper smaller) ; the panicle perhaps more elonga- 

 ted; and the scales of the involucre broader and more obtuse. 



t t + Leaves entire, or slightly seiTate, the primary veins nearly obsolete ; the mi- 

 nutely pellucid-reticulate veinlets inconspicuous except by transmitted light: 

 heads small: scales of the 5-15-flowered involucre few, membranaceous, narrow. 



52. S. p27osa (Walt.) : stem hirsute with spreading hairs, strict, often 

 branching above, very leafy ; leaves oblong-lanceolate, serrulate, slightly 

 scabrous, mostly hairy along the midrib, often pubescent beneath, obscurely 

 veined ; the upper ovate-lanceolate or oblong, erect, closely sessile, mostly 

 entire; the recurved racemes disposed in a c(ense pyramidal panicle; rays 

 7-10, scarcely longer than the about 5 disk-flowers; achenia minutely pu- 

 bescent.— IFa/^ .' Car. x>- 207, not of Mill. diet. ? S. altissima, Mickx. ! fl.

Damp soil, from Florida ! Alabama ! and Louisiana! to the pine barrens 

 of New Jersey ! Sept.-Oct. — Stem 3-7 feet high, robust, villous-hirsute, es- 

 pecially towards the summit, with whitish jointed hairs, often paniculately 

 branched at the summit ; the branches or the numerous racemes recurved- 

 spreading. Leaves thickish or rather firm, pale green, closely sessile or 

 partly clasping, nearly veinless except by transmitted light, or sometimes 

 with the primary veins apparent; the prominent midrib, and often the sca- 

 brous margins fringed with long hairs; the surfaces often glabrous, but some- 

 times scabrous-pubescent above and villous-pubescent beneath : lower leaves 

 2-3 inches long, lanceolate-oblong, sharply serrulate, mostly acute, often nar- 

 rowed at the base ; the upper gradually reduced to about half an inch in 

 length, 3-5 lines in width. Heads very numerous, about as large as in S. 

 odora. Bracts subulate. Exterior scales of the glabrous involucre lanceo- 

 late-subulate ; the inner linear. Pappus about as long as the corolla of the disk. 



53. S. odora (Ait.) : stem simple or sparingly branched, somewhat pubes- 

 cent in lines, often declined ; leaves linear-lanceolafe, entire, very glabrous, 

 with minutely scabrous margins, punctate with pellucid dots ; racemes pani- 

 culate ; rays 3 or 4, rather large ; the disk-flowers 3-4 ; achenia minutely 

 hairy.— ^if..' Kew. {ed. 1) 3. j^- 214,- Pursh, fl. 2. p. 539; Ell..' sk. 2.

(i. leaves less evidently punctate, and nearly destitute of anisate odor. 



Borders of thickets, in dry or sandy soil, Canada (Pursh) and New Hamp- 

 shire ! to Florida! and Louisiana I (Also a Mexican & South American 

 species?) Aug.-Oct. — Stem 2-3 feet high, rather slender, often reclined. 

 Leaves closely sessile, spreading, or at length reflexed, 1 to 3 or 4 inches 

 long, one-fourth to more than half an inch wide near the base, tapering to a 

 point; the midrib prominent and smooth; the veins and minutely reticulated 

 veinlets inconspicuous except by transmitted light. Panicle mostly secund, 

 as well as the racemes. Pedicels slender. Bracts subulate. Scales of the 

 involucre few, nearly glabrous; the exterior short; the others linear, rather 

 acute. Pappus shorter than the corolla of the disk. — The leaves yield a 

 volatile oil by distillation, and when bruised exhale a fine anisate odor. A 

 plant is frequently found growing with the ordinary S. odora, which is only 

 to be distinguished by tlie absence of this agreeable odor, having instead 

 the scent of'S. Canadensis, &c. ; but the pellucid dots, or reservoirs of vola-
