by a clasping base, sparingly floccose-tomentose, few and dimin- 
ishing upwards: heads large, terminal, solitary, almost 3™ in 
diameter ; involucral bracts densely clothed with brown wool, 
linear-oblong, acute, 6™ long: rays about 14, oblong, }- 
toothed ; disk corollas with campanulate limb, the slender tube 
longer than the pappus: akenes striate, glabrous. 
This may be another species, as it differs in the shape of the disk 
corollas. The limb in this is more abruptly contracted at base to a more 
slender and longer tube. In all other respects the two seem identical.

cauline mostly near the base, narrowly acuminate, dentate 
below the middle; upper part of stem generally leafless to the 
inflorescence which is subtended by 1 or 2 leaves: head cym i
