11. CARMINATIA, Mo^no. (Prof. B. Garminati, of Pavia, wrote on 

 the materia medica.) — ■ Single species, an annual ; with opposite or partly alter- 

 nate broad and long-petioled thin leaves, and racemiform-paniculate heads of 

 whitish flowers. — DC. Prodr. vii. 267; Deless. Ic. Sel. iv. 98. 



C. tenuifiora, DC. 1. c. Sparsely pubescent or hirsute : stems a foot to a yard high, ter- 

 minating in a leafless virgate panicle : leaves broadly deltoid-ovate, as wide as long, repand- 

 dentate, veiny, often shorter than the petiole : heads half-inch long : soft pappus bright 

 white. — Gray, PI. Wright, ii. 71. — New Mexico and Arizona, Wright, &c. (Mex., first 

 coll. by Motjino.) 



12. KtTHNIA, L. (Dr. Adam Kuhn, of Philadelphia, took the original 

 species to Linnaeus.) — Perennials of Atlantic U. S. and Mexico ; with chiefly 

 alternate leaves (more or less sprinkled with resinous atoms, as in allied genera), 

 usually, with scattered or corymbosely cymose heads, these of 10 to 30 whitish 

 or at length purple flowers, produced in late summer or autumn : pappus mostly 

 tawny. — Spec. ed. 2, ii. 1662 (excl. syn. Pluk.), & Gen. ed. 6, 95 (the anthers 

 wrongly described, from imperfect or monstrous blossoms). Oritonia, Gaertn., 

 not Browne. Kuhnia § Strigia, DC. Prodr. v. 126. 



K. SchAffneri, Gray, Proc. Am. Acad. xvii. 207, of Mexico, is a peculiar species, with 

 scapiform monocephalous peduncles and tuberous roots. The rest of the genus is the fol- 

 lowing. 



K. eupatorioid.es, L. Stems wholly herbaceous, 2 or 3 feet high : leaves from oblong- 

 (or even ovate-) lanceolate to linear, irregularly few-toothed or upper ones entire, the lower 

 narrowed at base and sometimes short-petioled : pubescence minute or soft and cinereous, or 

 hardly any: heads more or less eymose-clustered. — L. f. Dec. ii. 21, t. 11; Torr. & Gray, 

 PI. ii. 78. K. eupatorioides & K. Critonia, Willd. Spec. iii. 1773. K. dasypia, glutinosa, 

 elliptica, tuberosa, fulva (media, glabra), & pubescens, Raf. Ciitonia Kuhnia, Gairtn. Pruct. 

 ii. 411, t. 174, f. 7; Michx. PL ii. 101. — Dry ground, New Jersey and Penn. to Montana, 

 and south to Texas. Very variable; the extreme forms are 



Var. corymbtllosa, Tore. & Gray, 1. c. A foot or two high, stouter, somewhat 

 cinereous-pubescent or tomentulose : leaves rather rigid and sessile, from oblong to lanceo- 

 late, coarsely veiny : heads rather crowded. — K. glutinosa, Ell. Sk. ii. 292, not DC. 

 K. suaveolens, Fresen. Ind. Sem. Francf. 1838. K. Maximiliani, Sinning in Neuwied. Trav. 

 K. macrantha, Buckley in Proc. Acad. Philad. 1861, 456. — Prairies and plains, Illinois to 

 Dakota and Nebraska, and south to Alabama and Texas. 



Var. gracilis, Tore. & Geat, 1. c. Leaves from lanceolate to very narrowly linear, 

 few-toothed or all but lower entire, minutely pubernlent or nearly glabrous : general inflo- 

 rescence more open and paniculate. — K. paniculata, Cass. Diet. xxiv. 516; DC. 1. c. K. Cri- 

 tonia, Ell. 1. c. — Carolina to Florida, Alabama, &c. Seems to pass into the following. 

 K. rosmarinif olia, "Vent. Perhaps more lignescent at base, a foot or two high : leaves 

 all entire, linear or linear-lanceolate, mostly with revolute margins, and the upper almost 

 filiform, from a quarter of a line to 2 lines wide, somewhat scabrous : heads more scattered 

 or paniculate : plume of the bristles of the pappus perhaps a little shorter. — Hort. Cels. 

 t. 91 (poor figure of a broadish-leaved form, with too much imbricated involucre) : DC. 1. c.

13. BRICK^LLIA, Ell. (Dr. John Brichell of Georgia, correspondent 

 of Muhlenberg and Elliott.) — Herbs or undershrubs ; with opposite or alternate 

 veiny leaves, and variously disposed heads of white, ochroleucous, or rarely flesh- 

 colored flowers, in late summer. A genus of about 40 species, of the warmer
