It is mostly similar to N. aghrica, but can be readily distinguished by the presence of apical placentation and orbiculate fruit with wings extending almost evenly from the base to the apex. Its phylogenetic relationships within the genus are provided based on the nuclear-encoded ribosomal internal transcribed spacer region. Carpological and ecological features of N. ali-atahanii and related species are also discussed. Key words: Brassicaceae, new species, flora of Turkey, internal transcribed spacer, Noccaea, placentation 1. Introduction The genus Noccaea Moench was described by Moench (1802), and its species have long been considered a part of Thlaspi Linnaeus (1753), until Meyer divided it into 12 genera (Meyer 1973, 1979). The generic concept by Meyer is still under criticism by several authors (Al-Shehbaz, 2014; and references given therein). Recent molecular phylogenetic studies have clearly shown that Thlaspi consists of representatives of 3 different lineages, . Thlaspi . from Thlaspideae, Noccidium . (1973) from Camelineae, and the rest of the segregates from Coluteocarpeae (Koch et al., 2012; Koch and .
