Ornithogalum sandrasicum Yıld. is a species endemic to Turkey. Anatomical characteristics of the species have been the subject of study. Cross-sections of the root, stem, and leaf parts of the plant have been examined. The objective of this study was to identify distinctive anatomical characteristics that could serve as a taxonomic aid in distinguishing the O. sandrasicum species. The uniformity of crystal type and distribution can be regarded as a taxonomic character in the classification of species. Raphid crystals were observed in stem and leaf sections. The number of vascular bundles in the stem, the number of cortex and sclerenchyma layers, and the distinction of mesophyll type in the leaf can be used as diagnostic characters for Ornithogalum species.
