and softly cinerescent-pilosulous with ascending hairs with small 
tuberculate-subglandular bases, beneath very densely and softly 
argenteous-pilose (sometimes yellowish-tinged) with subappressed 
lucid hairs, triplinerved just above the base, the primary veins 
evident beneath, the secondaries mostly concealed by the pubes- 
cence; branch leaves smaller, sometimes subentire; heads 2-3 cm. 
wide, in corymbose panicles of 3-9 at tips of branches and branch- 
lets, the pedicels 1~5.5 cm. long, densely tomentulose-pilosulous; 
disk depressed-subglobose, 8 to (fruit) 14 mm. high, 1.2 to (fruit) 
1.8 cm. wide; involucre 3-seriate, graduate, 9-15 mm. high, the 
phyllaries lanceolate or lance-elliptic to oblong-lanceolate, with 
indurate vittate base and shorter or equal to (outermost) longer 
reflexed or spreading acute herbaceous tips, densely sericeous- or 
cinereous-pilose-tomentose outside above the sparsely pubescent 
indurated base, the herbaceous apex densely pilosulous; receptacle 
slightly convex; rays 12, golden yellow, neutral, the lamina hirsu- 
tulous dorsally, elliptic-oblong or oval, 2 or 3-denticulate, 7-13 mm. 
long, 3-5.5 mm. wide; disk corollas yellow, hirsutulous chiefly at 
base of throat and on teeth, 5.5mm. long (tube 1.6 mm., teeth

Ecuapor.—Huigra, Province of Chimborazo, August 3, 1920, E. W. D.and 
M. M. Holway 815 (type in U.S. National Herbarium no. 1058651); same 
locality, August 18 and September 6, 1918, J. N. and G. Rose 22171 and

g This rather handsome species is related to H. imbaburensis and H. lehmannii 
Hieron., both of which are now represented in the U.S. National Herbarium 
by fragments from the types. The former differs in its narrower entire leaves 
and much smaller heads, the latter in its black-purple disk and longer, acumi- 
nate phyllaries.
