Onosma hawramanensis(Boraginaceae), a New Species from Kurdistan, Iraq

Abstract

Onosma hawramanensis from Kurdistan, Iraq, is described and illustrated. Its relationship and distinguishing characters from nearest relatives in southwestern Asia are discussed. It is easily distinguished by the combination of setae with basal tubercles sparsely pubescent with small simple trichomes, and the non-accrescent fruiting calyx; the yellow corolla, pubescent outside and glabrous inside, the sparsely pubescent nectar annulus at the base of the corolla tube; the linear anthers, free at the base and bidentate at the apex; and glabrous, glossy, broadly ovoid fruits with the surface slightly reticulate.
