The genus Heptaptera Apiaceae consists of eight species distributed in Southern Europe and Southwest Asia. Among them, H. cilicica being endemic, H. anisopetala, H. anatolica and H. triquetra species occur in our country. n this study, evolutionary family trees were calculated using the maimum likelihood and Bayes approaches based on the ribosomal DNA TS 1, .S rRNA, TS 2 seuence dataset of Heptaptera species distributed in Turkey, as well as H. angustifolia, which is endemic to taly, and H. microcarpa, which grows in Syria. Nine morphological characters, which are considered to play a role in intragenus classification, were mapped on the Bayesian hypothesis tree. Seven of these were found to be plesiomorphic for the genus. Being cylindric crosssection of the basal part of the stem the presence of stalked papillae on the stem the pinnate basal leaf bracts standing upright flat stylopodium the fruit length less than 1 mm the inverted ovoid fruit shape are the plesiomorphic character states for the genus Heptaptera. t has been determined that the wings in the mericarps are a genusspecific synapomorphic character state.
