Turkish Journal of Botany
The tribe Nigelleae Schröd. (Ranunculaceae) worldwide distribution has been studied taxonomically, based on morphological, palynological and seed morphological characters, as well as chromosome counts. Extensive field works have been carried out in Turkey, Greece, Iran, Syria, Lebanon, Portugal and in Northern Cyprus. Moreover, the specimens of major herbaria in Turkey, Ukraine, Russia, Syria and Iran as well in Europe have been examined. This study represents the most comprehensive monograph of the tribe based on field work across its nearly entire distributional range, complemented by examination of over 980 specimens from 25 herbaria and our collections with nomenclatural contributions.

Asperula cankiriense B.Şahin & Sağıroğlu, a new species discovered in the central Anatolian region of Turkey (Çankırı), is described herein. A. cankiriense is similar to Asperula bornmuelleri Velen. However, A. cankiriense differs mainly in its habitus, stem, leaves, and inflorescence features. In this study, the diagnostic morphological features, distribution, habitat and ecology, etymology, conservation status, and taxonomic features of the new species are discussed. Additionally, pollen micromorphological characteristics of A. cankiriense and A. bornmuelleri are examined and compared using light microscopy (LM) and scanning electron microscopy (SEM) analyses. The pollen grains are subprolate, aperture type 6?7 or rarely 8 zonocolpate …
