194 LEAFLETS. 



small, IJ to 2} inches long including the narrow petiole, not in 

 the least lyrate or otherwise lobed, broadly cuneate-oblong, 

 acutish, saliently dentate, often coarsely so, thin, glabrous above, 

 beneath more or less canescently thin-tomentose : scapes very 

 slender, J to 1 foot high, with few erect bracts and a long nar- 

 row head, the bracts of the involucre few, lance-linear : achenes 

 canescently somewhat villous, short-beaked. 



Mountains of middle Mexico, at 9,500 and 10,000 ft., C. G. 

 Pringle, numbers 6411 (type) and 9882 as in U. S. Herb., both 

 labelled C. Seemannii, to the description of which species these 

 specimens in no wise respond even remotely. 



C. CRISPULA. Rootstock short, upright : leaves 1^ to 3 inches 

 long, cuneate-oblong, or some tapering more spatulately, obso- 

 letely denticulate and more or less crisped, never in any way 

 lobed, thinnish, glabrate above, densely tomentose beneath : 

 scape mostly solitary, naked, flocculent, as also the subulate- 

 linear and linear bracts of the involucre : achenes small, glab- 

 rous, pappus-stipe filiform, twice the length of the achene.

0. DIVEKSIJOLIA. Rootstock s'hort, ascending, bearing unu- 

 sually copious fleshy-fibrous roots : leaves rather few, thinnish, 

 light green and glabrous above, thinly tomentose beneath, not 

 concealing the many feather veins, the outline various, the ter- 

 minal lobe in some subcordate-deltoid and with only a nearly 

 straight wing-like border running down below it, in others more 

 oval and with a pair of more or less lyrate lobes above the wing- 

 like basal margin, the margins of all terminal lobes lightly 

 retrorse-crenate and retrorse-denticulate : scapes 1 to 3, com- 

 monly W feet high, fiocculent, naked : involucre more than an 

 inch high, its bracts all very narrow, and, by involution of the 

 margin, appearing almost filiform : achenes small and slender, 

 delicately scaberulous, surmounted by a filiform stipe of 4 times 

 their length.
