    Towards a better understanding of Prunus (Rosaceae): molecular and morphological notes on Prunus subgenus Cerasus in Turkey
    (Oxford University Press, 2023) Ciftci A.; Gercek Y.C.; Mollman R.; Bostanci Ordu P.I.; Yazici C.; Yaprak A.E.; Morgil H.; Şik L.; Erol O.
    In this study, we explore the relationships among taxa of Prunus subgenus Cerasus in Turkey using a combination of macromorphology, micromorphology and molecular techniques. We recorded qualitative and quantitative characteristics of flowers, leaves, seeds and endocarp for 96 populations representing 14 taxa of Prunus subgenus Cerasus. ITS, matK, ycf1, trnL-trnF DNA sequence data were used to reconstruct phylogenetic trees for this group. Haplotype analyses results found 11 haplotypes among the samples used in this study. We also note that the infraspecific taxa of Cerasus angustifolia (=P. albicaulis), P. mahaleb, P. microcarpa and P. prostrata, as described by previous authors, do not exhibit significant differences even among the features of foliar morphology that are so often used to distinguish them from one another. As a general rule, our analyses indicate that the highly variable features of leaf micromorphology and endocarp and seed micromorphology are not taxonomically significant. In contrast, although floral morphology is often overlooked in systematic studies of Prunus subgenus Cerasus, we found several taxonomically useful flower characters, including sepal indumentum, hypanthium shape and indumentum and petal shape. This work clarifies the infraspecific relationships of members of Prunus subgenus Cerasus in Turkey and solves some taxonomic problems. © 2023 The Author(s).

    A new autumn-flowering Crocus (Iridaceae) from Türkiye: C. rifatozdemiri sp. nov.
    (Magnolia Press, 2024) Şik L.; Yazici C.; Mollman R.R.; Harpke D.; Kaleli B.S.; Çiftçi A.; Erol O.
    C. rifatozdemiri sp. nov. is a new autumn-blooming species from Crocus series Crocus described from three locations on Mount Çal in Muğla province in southwest Türkiye. The new species is notable for its large showy white flowers with sharply mucronate segment tips and contrasting bright red stigma branches. The exceptionally tall stigma is what most clearly differentiates the new species from its closest relatives, with its long branches that usually divide from above the anther tips, although other morphological features, such as tunic neck and tepal shape, as well as molecular data, support its separation from other members of series Crocus. nrETS and nrITS nuclear regions were used to infer the phylogenetic affiliation of the new species within series Crocus, resulting in a clear separation between it and closest relative C. kofudagensis, as well as other members of the series. Leaf anatomy was found to be similar to other members of series Crocus, which tend to show minimal differences between species. Finally, a full description and diagnosis, chromosome count, line illustration and figures detailing the features of this new endemic taxon, which is so far known only from one mountain in Türkiye.
