As part of a complete morphological study of Ornithogalum narbonense and O. nutans, based on live and dry Bulgarian material, their anatomical leaf structure was described and illustrated for the first time. The leaves are epistomatic in both. They differ in the dimensions and number of epidermal cells and stornata, in thickness and structure of the epidermal cutic1e, and most definitely in the shape and arrangement of mesophyll cells and in the structure of the leaf biade edge.
