The new species, Haplopappus alpinus of section Tonestus, is formally described and illustrated. It is endemic to the high mountains of central Nevada. Vegetative and floral morphology of related species is detailed. The new species appears to be most closely related to H. eximius but also demonstrates close affinity to H. aberrans (all three are diploids with n = 9).
