Özet
An evaluation was conducted of A. yamadagensis, which is a Critically Endangered (CR) species that is endemic to Turkey, comprising an analysis of its taxonomical, micromorphological, macromorphological, cytological and palynological features, in addition to its geographical distribution. Scanning Electron Microscopy was used to obtain seed and pollen surface microphotographs. The shape and sculpturing of the seed periclinal walls are convex and granulose. The shape of the pollen grains appears monocolpate, with polar and equatorial axes of 23.65 ± 0.29 and 14.92 ± 0.33 µm, respectively. A. yamadagensis has a pollen ornamentation that is foveolate-microreticulate. Cytological analyses revealed that A. yamadagensis is diploid and has a chromosome number of 2n = 2x = 16.
