Swertia barunensisP. Chassot sp. nov. from Nepal is described and illustrated. It was collected in 1997 in an alpine meadow in the Makalu Barun National Park at an elevation of 4200 m. It belongs to Swertia section Macranthos T.‐N. Ho & S.‐W. Liu and resembles S. pseudohookeri H. Smith, from which it differs mainly by the shape of the nectary and the exomorphic seed structure. A key to all the species of sect. Macranthos is provided. The affinities of S. barunensis with some other taxa in the subtribe Swertiinae (Griseb.) Rchb. are also briefly discussed. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 141, 389–394.
