rather soft hairs. Leaves alternate, oval or orbicular-ovate, 
acutish to obtuse, at base truncate-rounded or cordate, tripli- 
nerved, crenate-serrulate with about 20 pairs of rounded appressed 
teeth, reticulate beneath, densely dully cinereous-pilose-tomentose 
both sides and densely glandular-dotted beneath the hairs, 244 
em. long, 2-4 em. wide, on similarly pubescent petioles 3-4 mm. 
long. Heads (1-5) solitary and sessile at apices of stem and 
branches, leafy-bracted at base (the bracts nearly or quite as large 
as foliage leaves), 2.8 em. wide; disk 1.1—1.5 cm. high, 1.62.2 cm. 
wide. Involucre (excluding the outermost foliaceous bracts) 
about 4-seriate, scarcely graduated, about 1 em. high, the outer- 
most 1-2 series of phyllaries foliaceous, like the outermost bracts 
but smaller, the two inner indurated, chartaceous-coriaceous, 
oblong, truncate to obtusish at apex, densely subsericeous-pilosu- 
lous on back (except on margin). Rays about 13, linear-oblong, 
pilose and gland-dotted dorsally, 1 em. long, 1.8 mm. wide; disk- 
corollas sparsely pilose below and on teeth, 4.2-5.2 mm. long (tube 
0.9mm.). Pales indurate, strongly carinate, pilose on back above 
7-8 mm. long. Achenes at full maturity grayish, thickened, sub- 

quadrangular, rather deeply grooved on the lateral angles, some 
times also on the outer, the ridges all with pale narrow margins; 
more or less ciliate, prolonged above into ciliate teeth, the immer 
and sometimes also the outer into firm awns about 2 mm. long.
