Abstract

This study presents contributions to morphology palynology, chorology and threat category of Chamerion stevenii (Boiss.) Holub for the first time in Turkey. All samples used for the study are stored in the Herbarium of Recep Tayyip Erdogan University, Department of Biology (RUB). Locality information was compiled from the records of Flora of Turkey, the samples stored in national and international herbaria and author’s own collections. Distribution maps were created using ArcGIS 9.3 program and calculation of extent of occurrence (EOO) and area of occupancy (AOO) were carried out, and the threat categories were assessed according to red list criteria and categories of IUCN. Plants are perennial and characterized with linear-lanceolate leaves and densely strigillose hairs. Pollens are monad, trizonoporate, subisopolar and bilateral symmetrical and baculate ornamentation. C. stevenii was recorded from 28 distinct populations mainly in east part of Anatolia and the EOO is < 133,944 km2 and AOO is <35 km2. The morphological and palynological observations showed that C. stevenii differs from closely allied taxa C. dodonaei (Vill.) Holub. Due to size and population number, habitat qualities and threats in the habitat such as flood, C. stevenii is assessed under the Least Concern category (LC) in Turkey.
