Leucheria peteroana (Nassauvieae, Asteraceae), a new species of Leucheria endemic to the Andes of Central Chile, and insights into the systematics of Nassauviae

A new species, <i>Leucheriapeteroana</i> <b>sp. nov.</b>, endemic to a restricted area of the Andes of Central Chile, is here described. Using newly sequenced nDNA and cpDNA data, the phylogenetic affinities of <i>Leucheria</i> and closely related taxa within Nassauvieae are revisited. This new species shows a unique set of characters that clearly distinguish it from other species of <i>Leucheria</i>. Phylogenetic analyses place this perennial species close to annual species found in the pre-Andean environments of Central Chile. A detailed description, distribution map, insights about its habitat, conservation status, and photographs are provided.
