Asyneuma

Asyneuma is a genus of flowering plants in the bellflower family, Campanulaceae. They are native to North Africa and Eurasia.[2] Many are endemic to Turkey.[3][4] Plants of the genus may be known commonly as harebells, but this name can also apply to the entire family.[5] There are up to about 33 species.[2][6]

Characters used to identify Asyneuma species include a generally wheel-shaped (rotate) corolla with the petals fused at the bases and spreading outward into very narrow lobes, lacking or rudimentary appendages on the calyx, a stigma with 2 to 4 lobes, and an oblong or roughly spherical fruit capsule that breaks open via pores on the sides.[7] These characters are not always helpful in distinguishing Asyneuma from the closely related genus Campanula, because authors disagree on which character is more important: the extent to which the flower petals are joined versus the position of the pores on the fruit capsule. Molecular data has been required to determine the best genus in which to place certain species.[8]
