Confirmation of the Natural Distribution of Euphorbia condylocarpa M.Bieb. (Euphorbiaceae: Sect. Helioscopia, Subsect.Galarhoei ) in Türkiye

This study; it is about the verification of the distribution of Euphorbia condylocarpa Boiss. & Heldr. (Euphorbiaceae), for which there is no reliable information about its existence in Türkiye. Because, the most important website regarding the distribution of plants distributed in Türkiye(Bizimbitkiler website) and the most up-to-date and comprehensive study called "Bizim Bitkiler Listesi (Damarlı Bitkiler)” do not accept the existence of this species in Türkiye. It is stated that the existence of this species in Türkiye needs to be confirmed. The closest species to the E. condylocarpa, which we focused on in order to eliminate doubts about its distribution in Turkey, is in tuberous form Euphorbia apios L.. It is distinguished from E. apios by the fact that the cauline leaves of E. condylocarpa are cordate–auriculate at the base and the number of axillary rays is more than 6 (to 30). In addition, the description of E. condylocarpa, the ecological information in the area where it develops, and some features of the species that differ from the known description are also emphasized.
