Calea funkiana (Compositae, Neurolaeneae), a New Endemic Species from Serra do Cipó, Minas Gerais, Brazil

A new species of Calea belonging to sect. Meyeria is described and named as an in memoriam tribute to Vicki Ann Funk (1947–2019), who dedicated her career to plant systematics, specially focusing on the Compositae. Calea funkiana resembles Calea triantha, but is distinguished by the slightly branched habit, apically acute leaves, glabrous ray florets, and, mainly, the villose indumentum of stems, leaves, peduncle, and outer phyllaries. The new species is described and illustrated, its geographic distribution is mapped, and its taxonomic affinities are discussed. Additionally, a key for the species of Calea from Serra do Cipo, Minas Gerais, Southeastern Brazil, is provided.
