Minuartia in Turkey. The specimens were collected from Mount Erciyes (Kayseri). The new species is related to Minuartia erythrosepala (Boiss.) Hand.-Mazz. var. erythrosepala. M. hamzaoglui is an endemic species which has a distribution in Central Anatolia. The differences between the species are discussed. Description, distribution, illustration, and conservation status of the new species are given. Seed structures were examined by scanning electron microscopy. Key words: Alsinoideae, Minuartia, taxonomy, Turkey 1. Introduction The genus Minuartia L. is located in subfam. Alsinoideae (DC.) Fenzl in the family Caryophyllaceae. It comprises approximately 120 species that mostly occur in the northern hemisphere, with some species native to Brazil and Chile (Bittrich, 1993). Minuartia includes 7 sections and 74 taxa in the flora of Turkey (McNeill, 1967; Davis et al., 1988; Tan & Vural, 2000). In Turkey it is always possible to describe a new species (Göktürk, 2012; Hamzaoğlu, 2012; Mutlu & Karakuş, 2012). As a result of recent studies, 2 taxa [M. dianthifolia (Boiss.) Hand.-Mazz. subsp. cataonica McNeill and M. dianthifolia (Boiss.) Hand.-Mazz. subsp. kurdica McNeill] were determined as synonyms in this genus. In addition, 2 species [M. elmalia (Aytaç) Aytaç, Parolly & Ö.Eren and M. turcica M.Koç], 1 variety (Minuartia dianthifolia var. longipetala Parolly .
