Oregon, Dr. Scoulcr ! Douglas! Nuttall! and California, Chamisso ! to 

 the Rocky Mountains, Nuttall. — More panicu lately branched than any other 

 species of this division ; the long and slender branches terminated by small 

 clusters; the short and broadish heads all, or nearly all pedicellate: rays 

 16-20, a little exserted ; the disk-flowers 8-14 : appendages of the style of 

 the latter obtuse. Receptacle with the margins of the alveoli pilose, rather 

 than iinibrillate. 



X Sjjccies not sufficiently known to us, founded on native specimens. 



73. S. Jecemflora (DC.) : stem erect, terete, and (with the leaves) some- 

 what scabrous with a very short pubescence ; leaves oblong, mucronulate, 

 entire, somewhat triplinerved ; the radical attenuate at the base ; racemes 

 somewhat secund, disposed in a corymbose panicle ; scales of the glabrous 

 involucre linear ; heads 1 0-flowered ; the rays 5, very minute ; achenia 

 silky-villous. DC. pirodr. 5. p. 322. _ • 



Texas, in the eastern districts, Berlandier. Plant a foot high. DC. — 

 Perhaps it belongs to the corymbose division. 



74. S. rotundifolia (DC.) : stem erect, terete, puberulent, scabrous; leaves 

 oval, ovate, or obovate, obtuse, mucronate, the margins and both surfaces 

 very scabrous ; the lower crenate, the upper entire ; racemes erect, compact, 

 short, disposed in a narrow panicle; bracts roundish; scales of the involu- 

 cre glabrous, somewhat acute ; rays very small. DC. prodr. 5. p. 332. 



Texas, in the eastern districts, Berlandier. — Very distinct in the form of 

 its bracts. DC. 



75. S. Icpida (DC.) : stem erect, strict, terete, puberulent; leaves oval- 

 lanceolate, with a long cuneate entire base, coarsely serrate at the apex, acu- 

 minate, feather-veined, somewhat scabrous, especially the margins and the 

 veins beneath ; panicle erect, terminal ; scales of the glabrous involucre 

 linear, acuminate ; rays a little longer than the disk. DC. jJrodr. 5. p. 339. 



(3. subserrata (DC. 1. c.) : leaves slightly serrate. 



Nootka, Hcenke. — Allied to S. latifolia and S. ambigua. DC. 



76. iS. compacta (Turcz.) : racemes erect; stem ascending, strict, scabrous; 

 leaves oblong-lanceolate, tapering into a long petiole, entire, or the upper- 

 most serrulate, slightly scabrous, the margins ciliate ; heads densely glome- 

 rate, surrounded by leaves. — Turcz. in hull. soc. nat. Mosc. 1840. p. 73. 



Unalaschka, Turczaninow. — Perhaps the same as S. lepida, DC. 



77. S. data (Pursh) : stem hairy, terete ; leaves lanceolate, somewhat 

 hairy beneath ; racemes erect ; rays elongated. Pursh, fl. 2. p. 543. 



North America, {Herb. Banks.) Pursh. — Two plants are ticketed ' S. elata' 

 in the Banksian herbarium : one, a cultivated specimen of a maritime 

 species, is S. integrifblia, Desf. SfDC: the other is marked ' New Jersey, 

 Bartram'' ; and has a hairy stem, corymbosely branched above ; elliptic 

 serrate leaves, which are hairy on both surfaces and ciliate; erect racemes ; 

 rather rigid and minutely strigose-canescent scales of the involucre (the outer- 

 most ovate, short; tbe inner oblong-lanceolate, slightly pointed, all somewhat 

 carinate) ; and strigose-canescent achenia. Dr. Boott has remarked its great 

 similarity to " S. Narbonensis, Pourret, in act. Tolas. 3. p>. 329" (of which 

 we have seen no description), from which we suspect it is not distinct. 



78. S. pauciflj}ra (Raf.) : stem simple, smooth ; leaves oblong-lanceolate, 

 acute, entire ; flowers 1-5, terminal. — Raf. in mcd. repos. {hex. 2) b. p. 359. 



Gloucester County, New Jersey, and Kent County, Delaware, Rafinesque.
