the akene, subulate, serrulate, several smaller ones between; 
the enveloping scales pubescent, 7 mm. long. 
Vic. La Paz, 10,000 ft., 1889 (44). = Rusby 1683, 1684 and 
2714. This species, though closely related to the next, is well 
distinguished by its smaller leaves, sessile with different pubescence 
and apex, broader heads, doubly more numerous and smaller disk 
flowers, the form and size of corolla tube and especially in the rela- 
tive length of akene, disk scale and sete, and the style-branches 
not twisted. 
ribbed, the ribs connected by the secondary veins; peduncles 
stout, monocephalous; heads, exclusive of the rays, 2 cm. 
broad and about as high, the base little if at all concave, the 
lateral outline of the fruiting head nearly circular; involucre 
about 1 cm. high, gray-hairy, the scales lanceolate, long-acu- 
minate, prominently I-or 3-nerved; rays 2 or 3 times the 
length of the involucre; disk-corollas 6 mm. long, the tube 
blackish apex truncate, 1.5 mm. broad, below light brown, 
strongly ribbed, pubescent, the sete aristate, fully as long as 
the akene, purple, serrate, the enveloping scale 8 mm. long. 
Vic. La Paz, 10,000 ft., 1890 (382).=Mandon 35, not Rusby 
1683 nor 1684. 
Verbesina Vic. Cochabamba, 1891 (974). Possibly the 
same as Rusby 1721. 
Verbesina Vic. La Paz, 10,000 ft., 1889. (No. 4 in part, 
having the leaves small and not decurrent. May be regarded 
as No. 4.) Possibly this is V. Mandoni Sch. Bip. 
Verbesina Vic. La Paz, 10,000 ft., 1880. (No. 4 in part, 
having erect, elongated, decurrent leaves. May be called No. 
4 а). I incline to the opinion that all these specimens are 
distinct from one another and from all collected by Mandon or 
myself; but, recognizing the wide limits of variation in this 
genus, I shall secure abundant material before determining.
