Aster. COMPOSITE. 503 



6. Fremontii: stem leafy, simple, bearing one or two heads; leaves thin; 

 the caiiline mostly oblong-lanceolate ; exterior herbaceous; scales of the invo- 

 lucre loose (either numerous or few); the inner very narrowly linear, acute; 

 pappus white. — A span high: perhaps a distinct species, connecting the 

 Amelli with the Alpigenous Asters. 



38. A. ericoides, 3. villosus. Add syn. A. pauciflorus, Martens! in bull, 

 acad. Brux. 8 (1841), p. 67. — The A. ericoides, Schkuhr, handb. t. 245, is 

 a good representation of A. multiflorus. 



71 (a). A. anomalus (Engelmann! mss.): more or less cinereous-pubescent; 

 stem simple or racemosely branched above, the branches erect-spreading ; 

 leaves ovate or ovate-lanceolate, entire, acumiate ; the radical and cauline 

 cordate, on slender naked petioles (rarely somewhat serrate); those of the 

 flowering branches lanceolate, subsessile; scales of the hemispherical invo- 

 lucre numerous, imbricated in several series, appressed at the base, with 

 linear elongated and squarrose tips; achenia glabrous. 



On limestone rocks, the brink of precipices, &c., in Illinois and Missouri, 

 not uncommon. Dr. Engebnayin! Sept.-Oct. — A most remarkable species, 

 with nearly the foliage of Aster Shortii ; while the heads and involucre much 

 resemble those of A. oblongifolius, being equally squarrose, but rather smaller, 

 and scarcely glandular or granular. 



79. A. reticulatus (Pursh) should doubtless be stricken out, and the syno- 

 nym referred to Diplopappus obovatus, p. 184. 



106. A. glacialis (Nutt.) — Defiles of the Wind River Chain of the 

 Rocky Mountains, and also just below the snow-line, Lieut. Fremont! — The 

 latter specimens are only about two inches high, more pubescent ; the leaves 

 chiefly radical, short, and spatulate ; and the involucre quite villous in a 

 young state. — With the above, Lieut. Fremont also collected a specimen of 

 A. Andinus, Nutt., A. integrifolius, Nutt., S^-c. 



107. A. salsuginosus (Richards.) — Wind River Chain of the Rocky 

 Mountains, above 7000 feet, Lieut. Fremont ! Both var. a. Sf (S. (Leaves 

 varying from linear-lanceolate to spatulate-oblong : rays showy, violet- 

 purple), and, 



y. scaposus : caespitose, dwarf; scape slightly exceeding the obovate- 

 oblong radical leaves, naked, or with a few bracts, bearing a single head. — 

 Probably gathered near the snow-line. 



110. A. graminifolius (Pursh). — New Hampshire, Mr. Eddy ! in herb. 

 Tuckerman. 



116. A. {Orthomeris) gluucus. — Wind River Chain of the Rocky Moun- 

 tains, at the elevation of 7000 feet or more, Lieut. Fremont! — A close con- 

 gener of A. elegans (of which Lieut. Fremont gathered a single specimen 

 near the same locality !) : rays several, small : achenia slightly hairy. 



121. A. [Oxytripolium) angustus. — Saline swampy margin of the Lake 

 of the Woods, and of Devil's Lake, Mr. Nicollet ! 



SOLIDAGO, p. 105. 



23. S. humilis, (3. — Abundant in the Notch of the White Mountains of 

 New Hampshire ! (where it was first collected by Mr. Tuckerman !) Near 

 the Willey house, several specimens of this ])lanf, and also of S. altissima, 

 were collected with greenish-white or cream-colored rays ! 



24. S. Virga-Aurea, y. multiradiata. — Wind River Chain of the Rocky 

 Mountains, from 7000 feet in elevation to near the snow-Hue, Lieut. Fre-
