A species of the section Ochractinia, nearest the Brazilian 
V. macrophylla (Cass.) Blake,* which has a more definitely 
pubescent stem, and leaves with fewer lobes and more densely 
pabescent with longer hairs beneath. The vernacular name is 
“‘cerbatana.’

Gardn. Lond. Journ. Bot. 7: 406. 1848, fide Baker.—This transfer is made 
on the basis of the equation of Cassini’s and De Candolle’s names by Ben- 
tham & Hooker (Gen. Pl. 2: 380. 1873), who had examined a head from 
Cassini’s type, and by Baker (loc. cit.). Cassini’s description agrees fairly 
well with this plant, except that the heads are described as rayless and yellow. 
Probably the rays, which are not obvious in the young heads, were over- 
looked by Cassini. No yellow-flowered Verbesina with alternate, pinnately 
lobed leaves is known. The name Ditrichum macrophyllum is usually cited 
from Bull. Soc. Philom. 1817: 33, but only the generic name appears in that 
paper.
