194 LEAFLETS. 
small, 14 to 24 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, 4 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 14 to3 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. 
At 3000 feet in the mountains of Santa Rosa, Guatemala, 
1892, Heyde & Lux, n. 3433 as in U. S. Herb. 
C. DIVERSIFOLIA. Rootstock short, 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 13 feet high, flocculent, 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.
