THE GENUS ESPELETIA 
stout, bearing a few alternate leaves similar to the basal ones but 
much smaller, corymbosely branched above, the branches few, erect 
or nearly so, densely tomentose with dark brown hairs, the pubescence 
of the lower part of the stem lanate, white; heads rather numerous, 
12 to 15 mm. broad, on stout erect peduncles 2 to 5 cm. long, these 
densely tomentose with brown hairs; bracts of the inflorescence i to 2 
cm. long, oblong-lanceolate, alternate; involucral bracts numerous, 
linear-lanceolate to narrowly ovate, acute or acuminate, glabrous 
within, densely villous outside with long matted brown hairs; rays 
numerous, 5 to 6 mm. long, shallowly bilobate at the apex; palese of 
the disk densely villous outside; corolla lobes densely pilose; achenes 
1.5 mm. long, obtusely angled, dark brown. 
Type in the U. S. National Herbarium, no. 602484, collected in 
the Paramo del Jabon, State of Truiillo, Venezuela, at an altitude of 
3,000 to 3,200 meters, in October, 1910, by Dr. Alfredo Jahn (no. 165). 
This is related to Espeletia argentea but is easily distinguished by 
the radiate heads, narrow radical leaves, and alternate cauline leaves. 
It is a handsome plant by reason of its silvery leaves which contrast 
with the brown pubescence of the inflorescence. 
Closely related to this is a specimen collected by Doctor Jahn 
(no. 244) at La Culata, Cordillera de Merida, at an altitude of 3,500 
meters. The form of the leaves is almost exactly the same as in 
E. pannosa, except that they are 40 cm. long and acuminate. The 
inflorescence is represented only by a few lateral branches, each sub- 
tended by a large, silvery bract, and terminated by several sessile 
heads. This specimen probably represents an undescribed species, 
but it is not complete enough to determine all the essential characters. 
12. Espeletia floccosa sp. nov. 
Radical leaves broadly linear, of nearly uniform width throughout, 
slightly dilated at the point of attachment, 30 cm. long, 9 to 11 mm. 
wide, acute or acuminate, coriaceous, rigid, erect, flat, densely sericeous 
on the upper surface with long, matted, silvery white hairs, densely 
tomentose on the lower surface with matted, white or yellowish hairs, 
the midrib large and prominent beneath, the lateral nerves not visible; 
flowering stem nearly a meter high, very stout, bearing a few long 
alternate leaves below, corymbosely branched above, the branches 
numerous, stout, erect, alternate, densely covered throughout with 
very long white wool, this loose and floccose; heads numerous, 18 to 
25 mm. in diameter, on stout peduncles i to 4 cm. long; involucral 
bracts numerous, linear, attenuate, 10 to 15 mm. long, glabrous 
within, densely covered outside with long loose white wool; paleae of 
the disk narrowly linear, rigid, erect, 5 to 6 mm. long, acute, pubescent
