Te revision of the section Alopecuroidei of the genus Astragalus (Fabaceae) in Turkey

Abstract

In this research, the morphological, anatomical, palynological, and cytological characteristics of the section AlopecuroideiDC. species belonging to genus Astragalus L. in Turkey were studied. As a result of this study, the members of the Alopecuroidei sectionrepresented by 22 taxa were evaluated under 24 taxa. While 3 taxa were reduced to synonyms, 4 new taxa have been added to theliterature. Tose are Astragalus aytatchii Akan & Civelek, A. ovabaghensis Akan & Aytaç, A. bahcesarayensis Akan, Fırat & Ekici, and A.ekicii H.Duman & Akan. In addition, it was determined that A. edmondi (Kuntze) Sheld. and A. maximus Willd. var. dasysemius Chamb.& Matthews were synonymies of A. decurrens Boiss. and A. alopecurus Pall., respectively. Although A. macrocephalus Willd. subsp.macrocephalus, A. erythrotaenius Boiss., and A. bracteosus Boiss. & Noé were previously stated to be endemic for Turkey, they are nowfound not to be endemic. Moreover, it was decided that Astragalus trichocalyx Trautv. is illegitimate and the name of A. petropolitanusSheld. is valid. In this study, Astragalus genufexus Freyn & Sint. was reevaluated as a distinct species.
