Type.

Based on Paepalanthus karstenii Ruhl.

These unusual specimens with large capitula, broadly rounded bracts, coarsely ciliate leaves, and irregular leaf lengths appear intermediate between Paepalanthus pilosus and Paepalanthus dendroides as to bract characters and habit, and were collected at an elevation where distributions would potentially overlap. A topotype (Paramo de Chipaque, 3000 m, Dec 1855, J. J. Triana 1022-5, COL [COL 000302503]), det. Paepalanthus dendroides by Killip, has similar features but even wider variability. This may be a variant of Paepalanthus pilosus or a hybrid taxon and needs closer study.
