North America? (obtained by Nees, in the year 1802, from the Marburg 

 garden.) Sept. (v. sp. in. hort. Berol.) — Nees has strangely confounded this 

 species with the widely different A. acuminatus, Michx. It resembles A. 

 praecox, and is also compared with the following species. The lower leaves 

 are scabrous and tapering to the base, while the uppermost are smooth and 

 closely sessile by a broad base. Perhaps it is not of American origin. 



84. A. patulus (Lam.) : stem glabrous, racemose-paniculate; the branches 

 spreading ; leaves oblong, deeply serrate, tapering into a petiole ; the upper 

 surface glabrous, or rough with a very minute pubescence; the lower gla- 

 brous; the niargins scabrous ; involucre imbricated [achenia glabrous]. DC.

North America. — This is doubtless of Ainerican origin, and was perhaps 

 derived from Canada; but we have never met with an indigenous specimen: 

 the A. Cornuti, Hook. fl. Bor.-Am. appears to be only a state of A. miser; 

 and is certainly ditferent from the plant cultivated under that name in the 

 Berlin garden. — The cultivated plant has much the habit of A. cordifolius, 

 &c., except that none of the leaves are cordate. Stein 2 to 3 feet high, 

 glabrous ; the spreading paniculate branches somewhat pubescent in lines ; 

 the heads mostly solitary on the branchlets. Leaves all very sharply 

 serrate, v.-ith more or less incurved teeth ; the lowermost elliptical, tapering 

 into a channelled petiole, acute, the base and apex entire ; the upper oblong 

 and oblong-lanceolate, much acuminate, narrowed below, sometimes into a 

 short margined petiole ; those of the branches sessile. Heads middle-sized. 

 Scales of the involucre imbricated in 3 to 4 series, somewhat unequal, subu- 

 late linear, acute. Rays numerous, narrow, blue according to De Candolle, 

 flesh-color turning purplish according to Nees. Achenia perfectly glabrous. 



85. A. stenophyllus (Lindl.): stem nearly glabrous, racemose; the 

 branches spreading, very densely racemose at the summit ; cauline leaA'es 

 linear-lanceolate, much acuminate, rather scabrous ; heads secund ; scales 

 of the involucre linear, acuminate; the inner membranaceous and colored.

North America? Cultivated in the English gardens. — Rays pale flesh- 

 color ; the disk changing. Lindl. — Placed between A. diffusus and A. miser. 



86. A. ohliquus (Nees) : stem glabrous below, racemose-compound above, 

 strict ; the branches somewhat corymbose at the summit ; leaves linear- 

 lanceolate, sessile, mucronate, somewhat entire, scabrous above, oblique ; 

 those of the branches spreading ; involucre lax ; the exterior scales larger, 

 spatulate-lanceolate, speading. Nees, Ast. p. 76 ; DC. prodr. 5. p. 237.
