of the leaves eomerimes scabrous. Heads large. Rays 8-10. Achenia, as 

 in all the species of this section, somewhat pubescent. — We have possibly 

 combined two or more species; but the form of the panicle, &c. is very vari- 

 able, and the fleshiness of the leaves probaby varies with the saltness of the 

 marsh; becoming almost membranaceous, as in var. ^., when the water is 

 nearly fresh. 



36. S. angustifolia (Ell.) : very glabrous ; stem erect, strict, simple, or 

 sometimes branched at the summit ; leaves thick, short, erect, lanceolate- 

 linear, sessile, mucronate-acute, 1-nerved ; the lower lanceolate, attenuate at 

 the base ; racemes short, erect or at length somewhat recurved, sometimes 

 secund, disposed in a close and virgate erect panicle; peduncles and pedicels 

 slender; heads small.— £/L / sic. 2. p. 388,- DC. ! prodr. 5. p. 341. 



In brackish swamps, Carolina! to Florida! Texas, Drummond ! Sept.- 

 Oct. — Plant with somewhat the habit of S. virgata. Stem 2-4 feet high, 

 simple and virgate, or producing slender branches near the summit, and 

 terminated by a contracted crowded panicle ; the very numerous heads 

 smaller, and the scales of the invokicre narrower than in the preceding spe- 

 cies. Upper leaves about an inch long, often subulate; the lower more scat- 

 tered, less pointed, sometimes broadly lanceolate. — The leaves in the Texan 

 specimens are more appressed. 



37. iS. integrifolia (Desf.) : stem erect, simple, somewhat pubescent; 

 leaves lanceolate, sessile, acuminate, slightly and obsoletely triphnerved, 

 glabrous, entire, the lowest [rather obtuse] sparsely denticulate ; racemes 

 axillary, erect, somewhat panicled [forming an elongated rather large pani- 

 cle] ; pedicels pubescent; scales of the involucre acute ; rays elongated. DC.

"North America." — We have only seen cultivated specimens, the origin 

 of which is uncertain. The summit of the stem, peduncles, &c. are pubes- 

 cent ; the heads large ; and the achenia pubescent. 



***** Racemes spreading or recurved (^scorploid^, secund : leaves veiny {sometimes 

 indistinctly triplinervcd), usually serrate. — Secundiflorae. 



+ Leaves usually ample, serrate, loosely feather-veined ; one of the veins on each 

 side of the midrib sometimes stronger than the others, thus appearing slightly tripli- 

 nerved: heads middle-sized. 



38. S. elliptica (Ait.): stem erect, glabrous; leaves elliptical, smooth, ser- 

 rate; racemes paniculate, secund; rays middle-sized, [peduncles and pedi- 

 cels minutely pubescent; scales of the involucre narrow, acute; achenia 

 strigose-pubescent]. Ait.! Kew. {ed. 1) 3. p. 214 ; not of Ell., nor of DC?

North America, Hort. Kew. Canada, Mill, did., in which the subjoined 

 particulars are given. — " Stalks stiff, round, smooth, with a white bark, up- 

 wards of 3 feet high. Leaves spear-shaped, smooth, with several veins, 3i 

 inches long, one inch broad, alternate. Flowers from the upper axils, in 

 short, erect, obtuse spikes, of a pale yellow color." — The characters we have 

 added to the phrase of the Hortus Kewensis are derived from the authentic 

 specimen, preserved in the Banksian herbarium. It is somewhat allied to 

 the maritime species; and the same plant, if we mistake not, is found along 

 the borders of salt marshes near New York. The latter has thickish, shining, 

 oblong-lanceolate leaves, veiny, smooth, with scabrous margins, the upper
