Aethionema aytachii (Brassicaceae): A new species from central Anatolia, Turkey

Abstract

Aethionema aytachii Ertuğrul & Hamzaoğlu, a new species from centralAnatolia that grows on marly hills in the AyaĢ district of Ankara Province (Turkey), is described and its relationships and distinguishing characters from the closest relative A. dumanii are discussed. The SEM of A. aytachii pollen is tricolpate, and its seed-coat sculpture is verrucate. Sequence data of the internal transcribed spacer region (ITS) of the new species was used to determine its phylogenetic position within Aethionema.

Aethionema sancakense Yıld. & Kılıç’ın (Brassicaceae) Anatomik, Palinolojik ve Tohum Yüzeyi Özellikleri

“…The monophylectic Brassicaceae family, to which Aethionema sancakense Yıld. & Kılıç species is a member, is a large family consisting of 345 genera and 4020 species distributed all around the world except Antarctica (Ertuğrul et al, 2021). The main spreading area of Brassicaceae are the Mediterrranean, Iranian-Turanian and Saharo-Sindian regions (Hedge, 1976).…”

“…In the first volume of Flora of Turkey, the number of Aethionema taxa in Turkey according to Hedge was 30 species, then Davis et al (1965) added 9 taxa and Adıgüzel (2000) added 5 taxa, the total number of taxa has reached up to 44. It is known that the number of taxa of Aethionema, which is named as "Rock Rose" in Turkey, has increased to 55 together with the newly defined species in taxonomic arrangement based on morphological observations only (Ertuğrul, 2012, Karabacak et al, 2013Kandemir et al, 2017;Yıldırımlı & Kılıç, 2016-2018Ertuğrul et al, 2021). Some recent studies have revealed both stem-leaf anatomy and palynology of Aethionema taxa.…”
