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 􏰗ma􏰘imum likelihood􏰗 and 􏰗Bayes􏰗 approaches based on the ribosomal DNA 􏰌􏰖TS 1, 􏰙.􏰚S rRNA, 􏰖TS 2􏰍 se􏰛uence 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 intra􏰑genus classification, were mapped on the Bayesian hypothesis tree. Seven of these were found to be plesiomorphic for the genus. Being cylindric cross􏰑section 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 genus􏰑specific synapomorphic character state.
