Allium beypazariense (Amaryllidaceae), a new species from middle Anatolia (Türkiye)

Allium beypazariense, a newly discovered species from the A. section Codonoprasum, is described and illustrated in this study. The species is endemic to middle Anatolia, Beypazarı and Çayırhan districts in Ankara in Türkiye. This research provides a comprehensive examination of the species, including its morphology, phenology, leaf anatomy, seed testa micromorphology, and conservation status. A comprehensive description of this species is provided, including detailed photographs and illustration, geographical distribution map, habitat and ecology. Furthermore, the taxonomic relationships between Allium beypazariense and its closest relatives, A. opacum is thoroughly explored and discussed. The new species can be easily distinguished from the close species by its mucronate tepal apex, sessile ovary, different anther colour, and thick scape.
