Although Duseniella had been already referred to the subtribe Barnadesiinae by Jeffrey (1967), Cabrera (1977) placed it in the Mutisieae Gochnatiinae, probably because some of its characters deviate from those typical of Barnadesiinae, e.g., unarmed branches, non villose florets, and scaly pappus.
Cypselae glabrous to sparcely villose; pappus of scabrid, linear scales, or absent.
Cypselae villose; pappus of long and short, somewhat paleaceous, scabrid bristles.
Florets actinomorphic, tubularfunnelform, villose. Male capitula with actinomorphic, five-lobed corollas, anthers exserted, apical appendages acute, short, tails smooth; style bifid, branches dorsally papillose above and below the bifurcation point; female capitula with corollas actinomorphic, shorter than the male corollas, four- to five-lobed; anthers absent or reduced to staminodes; style bilobed, widened below the branch bifurcation point, branches flat, smooth.
