10 LEAFLETS. 



K. BBTUL^FOLIA. Near K. occidenialis, like it in size and 

 habit, but all the foliage opposite ; leaves of broad and deltoid 

 outline, with an abrupt acumination and coarse serrate teeth : 

 inflorescence much more open and heads fewer ; bracts of the 

 iuTolucre broader, firmer, rather strongly 2-ribbed: corolla 

 pinkish, with broad and short throat and much more deeply 

 cleft limb : achenes black, hirtellous. 



This is Mr. Pringle'sn. 1263 from Chihuahua, distributed for 

 a variety of Eupatorium occidentale, from which it differs widely 

 by its opposite and very birch-like leaves, and still more certainly 

 by the form of its corollas, this in K. occidentalis being narrow 

 and tubular in comparison, with very short teeth. 



K. SUBINTBGKA. Shrubby, glabrous : leaves 3 or 3 inches 

 long, deltoid-ovate, acuminate, subtruneate or abruptly tapering 

 at base, short-petioled, obscurely and remotely denticulate : 

 cymes subsessile among reduced leaves at the ends of all the 

 branches : involucres long and narrow, the inmost of the few 

 bracts striate, the outer glabrous or glandular-puberulent: 

 corollas with slender tube and funnelform rather deeply cleft 

 limb : achenes setulose. 



Pringle's 3311 from San Luis Potosi, published by Mr. Robin- 

 son as a variety of E. Espinosarum, though specifically distinct 

 by characters of foliage, inflorescence, and especially by its 

 elongated heads. 



K. AMPLissiMA. Stout, Several feet high, branched above to 

 form a somewhat leafy thyrsoidal inflorescence : larger leaves 5 

 inches long, 3 or 4 in breadth, obtusely somewhat deltoid-ovate, 

 crenate, glabrous : pedicels and rather large involucres with a 

 short harsh pubescence: corollas tubular-f unnelf orm ; achenes 

 glabrous. 



Pringle's 2878, from Jalisco, Mexico, 1889, distributed as a 

 variety of E. amplifolium, from which this differs exceedingly 

 in habit, foliage, inflorescence and achenes ; for in the real K. 

 amplifolia there are angular and acute leaves, a naked-peduncled 

 terminal cyme, scaberulous achenes, etc. 



K. KUFA. Herbaceous, erect, 2 feet high or more, simple up 

 to the cymose-panicled summit, the stem, and leaves beneath, 

 of a dark red-purple, the petioles and nodes hirsute with a
