Özet:In this study, morphology, anatomy and systematics of the Genus Lathyrus L. (Leguminosae) in Central Anatolia is presented. Comparative morphological characters and their variation in the Genus; Calyx, leaf, corolla and pollen grains micro-morphology of the species; Anatomy of the species; Ecology, endemism, phytogeography and IUCN threat categories of the species; Numerical analysis and Revision of the genus in Central Anatolia were conducted. For the first time the calyx, corolla and leaf micromorphology, and the anatomical characteristics of Lathyrus were examined. Infrageneric delimitation of the species is performed by using multivariate analysis. As a result of morphological and anatomical data, it is suggested that L. haussknechtii should be classified as different species not variety of L. brachypterus. v The collected specimens was crosschecked with neighboring floras and the existing type specimens known from Turkey ANK, GAZİ, HUB, KNYA, CUFH, Erciyes, and Royal Botanic Garden Edinburgh (RBGE) herbaria. Morphological and micromorphological characters of pollen grains were revealed. It was determined that the pollen grains size and sculpturing were important diagnostic characters for the species. The statistical analysis was applied to compare P/E ratios of the pollen grains of studied taxa. According to this analysis, the P/E ratio is important diagnostic feature for most of the sections and the species. Sectional key and species key were prepared and updated. Expanded descriptions, GPS data, some photographs and some notes on the taxonomy of the species were given.
