CHAPTALIA. 191 



and in my own, gathered in from almost the whole extent of 

 southern North America, and northern and middle South 

 America. 



Out of these collections I find the following to have been 

 hitherto undescribed ; and there are more such, doubtless. 



I do not find ground for distinguishing, generically, between 

 Chaptalia and Leria. 



C. Texana. Plant with rather large foliage very thin, and 

 with the usually solit§,ry scape, from a short and not thick root- 

 stock : leaves commonly 4 to 6 inches long, lyrate by a few pairs 

 of small shallow lobes, the large terminal one oblong-oval, 

 acutish, obsoletely sinuate and not remotely retrose-dentate, the 

 upper face green but with a few conspicuous rolls of wool lying 

 along the midvein, beneath permanently white-tomentose but 

 thinly so : scape 8 to 16 inches high, bractless, floccose, not 

 thicker under the involucre, this an inch high, of fioccose- 

 tomentose linear acuminate bracts : small achenes scabrous, the 

 slender stipe of the pappus twice as long. 



Eocky sparsely wooded ground in western Texas, the type 

 Neally's 297 as in U. S. Herb., Lindheimer's n. 446 and the n. 

 674 of the Mexican Boundary Survey appear to be the same ; 

 perhaps also Reverchon's n. 1546, but that is doubtful. It 

 seems different. 



C. CARDUACEA. Smaller than the last, the foliage firmer, 

 hardly lyrate, the whole leaf sinuate-lobed, and somewhat 

 retrorsely so, but the upper lobes broader and more shallow, 

 the denticulation very sparse, upper face glabrous, lower white- 

 tomentose : scapes only 6 inches high, bractless, rigid, wiry, the 

 rather large heads nodding even in maturity ; bracts subulate 

 and subulate-linear, hard and rigid, pungentlyacute, tomentose: 

 achenes papillose-scabrous, shorter than the stipe of the pappus.

C. SONCHIFOLIA. Plant large, about 3 scapes a foot high, 

 the numerous leaves about 4 inches long, all from the 

 nearly obsolete crown of a cluster of long and soft whitish roots, 

 leaves thin, only thinly arachnoid beneath, above glabrate ex- 

 cept as to rolls of loose wool lying along the midvein, lyrate- 

 pinnatifld, the shallow rounded lobes each with % or 3 small
