Wedeliafigueiredoana (Asteraceae, Heliantheae), a winged cypselae new species of Wedelia for Brazil.
We describe one new species from Ceará state, Brazil: Wedeliafigueiredoana. It is morphologically associated with W.bonplandiana, but distinguished by 0.25-1.05 cm leaf blade width (vs. 1.5-2.6 cm), linear to narrow oblong leaf blade (vs. elliptic to spatulate), 3-seriate involucre (vs. 2-seriate), and cypselae 3.9-4 mm long (vs. 6-7 mm). An anatomical analysis of cypselae is provided, and we propose a more accurate terminology to describe similar wings to Wedelia species. We also provide a scientific illustration of the new species, photos of habitat, a map of its geographic occurrence, and its taxonomic affinities are discussed with a taxonomic key to the Wedelia species with the apically pronounced wings in the cypselae.
