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.
