Abstract

The aim of this study is to determine the species richness of the genus Astragalus in Kahramanmaraş and to present the updated distribution information with the help of Geographic Information Systems in a conservation point of view. In this study, country flora, recently published articles on the province of Kahramanmaraş, checklists, regional flora studies in the province, section revisions of Astragalus and also the plant samples collected from the field surveys in Kahramanmaraş were used. According to the results of the field studies supported by the literature, 95 plant taxa belonging to the genus Astragalus are listed together with their valid names and previous synonyms. The number of endemic taxa in Kahramanmaraş is 37 (with the endemism rate 39%). In the plant list, the largest sections of the genus Astragalus are Rhacophorus with 23 taxa, Onobrychoidei with 8 taxa, Dasyphyllium, Malacothrix, Myobroma, Proselius and Pterophorus with 6 taxa for each. The distribution of the taxa to the phytogeographical regions is as follows; 56 taxa (59%) Irano-Turanian element, 28 taxa (30%) Multi-regional or unknown origin, and the rest; 6 taxa (6%) is an element of the Eastern Mediterranean, 4 taxa (4%) of the Eastern Mediterranean (mountain) element and 1 taxon (1%) of the Euro-Siberian element. IUCN threat categories of endemic taxa were reassessed. As a result, totally 11 taxa are in threatened categories according to IUCN (4 taxa in CR, 2 taxa in EN and 5 taxa in VU categories) and the remaining 26 taxa are in lower threat categories (NT and LR). According to the distributions of species, which produced based on the grid system and the conservation point of view; (J13) in Çağlayancerit, (D4, E4 and G8) in Göksun, (I10) in the place between Ekinözü and central district, and (K10) in the central district of Kahramanmaraş were determined as the richest squares. These areas are very important in terms of conservation

Astragalus nurhakdagensis (sect. Hololeuce Bunge / Fabaceae), a new species from Turkey

“…An unusual Astragalus specimen was encountered in a flora survey conducted at Nurhak Mountain, which constitutes the highest peak of Kahramanmaraş Province (Killi Hill, 3071 m) (Uzun et al, 2019). Nurhak is a district located in Kahramanmaraş Province between the Irano-Turanian and Mediterranean regions of Turkey.…”

A Study on the Antioxidant Activity of Methanolic Extracts from Leaf, Stem and Flower Parts of Astragalus ovatus DC.

“…Astragalus L., which is used for medical purposes and consists of approximately 3000 taxa, is the largest genus of the Fabaceae family (Hardion et al, 2010). There are 466 taxa belonging to Astragalus in Turkey and it is stated that 218 of them are endemic (Uzun, Palabaş Uzun & Durmaz, 2019). Studies have shown that Astragalus species have biological properties such as antioxidant, antimicrobial and antiinflammatory (Albayrak& Kaya, 2018;Allam et al, 2013;Chen et al, 2012;Li et al, 2011).…”
