On the identity of the Turkish endemic Cyperus noeanus (Cyperaceae)

Abstract

Cyperus noeanus Boiss. is known only from the type specimen that was collected in Central Anatolia by Wilhelm Noë. It is considered an endemic species in Turkey. A detailed morphological study of the type specimen and comparison with similar related species in section Compressi Kunth demonstrated that the morphological characters of C. noeanus entirely fall within the range of characters of C. glaber L., which is a widely scattered species in Turkey, and widespread in S Europe and SW Asia as well. Based on our comparative study, we suggest that C. noeanus should be treated as a synonym of C. glaber.

A new species for the vascular flora of Algeria: Cyperus eragrostis (Cyperaceae)

“…The presence in Turkey, after a former citation for a single site («Costantinopel» : Kükenthal, 1935-36), is confirmed in 2018 along the Black Sea Coast (Şapci & Vural, 2018). The Caucasian Flora (Menitsky & Popova, 2006) treats C. eragrostis as a synonym of C. noeanus Boiss., a turkish endemic species; but the last is probably to be enclosed on the variation range of the annual C. glaber L. (Mesterházy & Verloove, 2018).…”
