Onosma demirizii (Boraginaceae), a new species from central Anatolia, Turkey

Abstract

Onosma demirizii Kaynak, Tarimcilar & Yilmaz sp. nova (Boraginaceae) is described as a new species from central Anatolia, Turkey. This new species is closely related to O. subulifolium H. Riedl but differs by its yellowish-green stems, patent-setose indumentum, linear to narrowly oblanceolate cauline leaves, shorther calyx and corolla and anthers that are longer than the filaments. The diagnostic morphological characters of this new species are discussed.
