Lactuca leucoclada . & Tuisl is newly recorded for Turkey, and for Lactuca viminea (L.) . & . and Lactuca quercina L., the presence of two distinct subspecies each in Turkey, L. viminea subsp. viminea and L. viminea subsp. ramosissima (All.) Arcang., and L. quercina subsp. quercina and L. quercina subsp. wilhemsiana (DC.) Feráková, respectively, are reported. The presence of Lactuca macrophylla (Willd.) , so far only doubtfully reported from Turkey, is confirmed in the present study. Emended descriptions, type information, updated distribution maps, and microphotographs of the taxonomically important achene features are presented for the studied taxa. Key words: Cichorieae, Lactucinae, micromorphology, new records 1. Introduction The subtribe Lactucinae (Asteraceae, Cichorioideae, Cichorieae) in its narrow modern sense was recognized by Bremer et al. (1994) with 17 genera (including Lactuca L., Scariola , Cicerbita Wallr., and Mulgedium Cass.). Later, Lack (2007) circumscribed Lactucinae to comprise 12 genera with 179 species. Based on .
