A new species Tulipa heweri is described (subgenus Tulipa, section Eichleres, series Multiflorae). The species is related to T. praestans and differs by having smaller and less densely ciliate leaves, yellow or ochre flowers, yellow filaments, anthers and stigma, and a green ovary. The two species are allopatric, T. heweri being endemic to northern Afghanistan. Crosses between T. heweri and T. praestans yielded moderate seed set.
