Delairea aparadensis (Asteraceae, Senecioneae), the first native species of the genus in the Americas

Este estudo foi realizado no âmbito do projeto PELD BISC. This work was supported by the CNPq/Capes/FAPs/BC-Fundo Newton/PELD nº 15/2016 and FAPESC/2018TR0928. We describe a narrowly endemic new species of Delairea from the highlands of southern Brazil. It is the second species described in this previously monospecific genus that was endemic to Africa, and the first record of a native species of Delairea in the Americas. Delairea aparadensis differs from D. odorata by its deltoid leaves and capitulescences composed by cymes of 2–6 capitula. Additionally, the new species is classified as critically endangered using the IUCN criteria.
