A new species Saussurea talungensis S.K.Ghimire & H.K.Rana, sp. nov. (sect. Strictae), from Talung valley of Humla district, Nepal, is described and illustrated. Morphologically, this species resembles Saussurea roylei and Saussurea lanata in habit, though it can be distinguished in having longer leaf petioles, purplish leaf margin, 1 or 3 capitula, shorter phyllaries, shorter receptacle bristles and the same anthers, comparatively shorter corolla with shorter lobes. Phylogenomic analysis also supports S. talungensis as a distinct species of Saussurea. Here, we provide taxonomic note, distribution map and phylogenomic inference to distinguish the new species and its allied members.
