428 BLAKE: NEw SouTH AMERICAN VERBESINAS 
Occidental, alt. 1500-1750 m:, 7-10 May 1922, F. W. Pennell 
5208 (type no. 1,140,129, U. S. Nat. Herb.). 
A species of Ochractinia, allied to V. synethes Blake, also 
Colombian, which has petioles margined nearly to the base, 
and leaves smoothish to the touch above and with a denser and 
more grayish pubescence beneath. Pennell & Killip 8034, from 
the Department of El Cauca, is so similar to V. nudipes in nearly 
all features that it might easily be a more pubescent form of it, 
but the flowers are described as yellow.

Very tall, herbaceous (?); stem glabrous, glaucescent; leaves 
alternate, large, pinnately lobed, harsh above, densely hispidulous- 
pilosulous beneath, the long petioles winged throughout, auriculate 
but not decurrent at base; heads rather small, radiate, white, 
main leaves ovate in outline, 35-48 cm. long (including petiole, 
this about 14 cm. long, winged to base, about 1.3 cm. wide, 
the wings forming auricles at base, not decurrent), 14.5-28 
cm. wide, pinnately about 9-lobed (lobes lance-oblong, acumin- 
ate, often falcate, subentire or sparsely serrulate toward apex, 
6.5-13.5 cm. long, 2-3.5 cm. wide, the second and third pairs 
hem 3-4 
cm , acuminate, cuneately narrowed into petiole, firm- 
papery, above deep dull green, harshly hispidulous, somewhat 
bullate, beneath dull grayish-green, densely an softly 
hispidulous-pilosulous with spreading straightish hairs, on costa 
ispid-pilose, the veins and veinlets impressed above u- 
lous-reticulate beneath; panicles axillary and doubtless terminal, 
1 and loose, up to 36 cm. long and 32 cm. wide, \ 
mm. long; heads 1.2-1.5 cm. wide; disk 7-9 mm. high, 5-7 mm.

obtuse, subherbaceous-tipped, sparsely hirsutulous and ciliolate, 
the inner (subtending the rays) whitish-stramineous, thin- 
tipped, acute, sparsely hirsutulous chiefly toward margin; rays

ate, 5-nerved, 5.5 mm. long; disk flowers about 26, their corollas 
hirsute-pilose on tube and lower throat, 4 mm. long; pales obtuse
