- MakaleAçık Erişim2024Scopus SJRQ2Mattiastrum pulumurense (Cynoglossinae, Boraginaceae), a new endemic species from Türkiye
Doğru Koca, Aslı; Gökmen, Mustafa; Yilmaz, Gülderen; Paksoy, Mehmet Yavuz
A new species, Mattiastrum pulumurense, has been described from Tunceli in eastern Türkiye. It is generally distinguished from other species (except M. racemosum var. scabridum) by a sparsely hairy or glabrescent above-ground part. It is most similar morphologically to M. longipes, M. calycinum, and Paracaryum hedgei (P. hedgei is potentially a member of the genus Mattiastrum). However, it differs from M. longipes and M. calycinum by its 3–3.5-mm-long and linear lanceolate scales, 2.5–4.5-mm-long anthers, and 10–15-mm-long styles; it differs from Paracaryum hedgei by its 3–3.5-mm-long scales, 2.5–4.5-mm-long anthers. In addition, this new species differs from M. racemosum var. scabridum by having 3–3.5-mm-long scales and no scale appendages. A description of the new species, an illustration, a comparative Table of morphological characters, detailed photographs, and a distribution map of the new species together with adjacent species were provided. In addition, the evolutionary relationships of these species were calculated using both Bayesian inference and maximum likelihood analyses based on the ribosomal internal transcribed spacer (ITS1-5.8S-ITS2) and combined chloroplast data set (rps16 and trnL genes, trnL-trnF intergenic spacer). According to the phylogeny-based combined chloroplast data set, both populations of Mattiastrum pulumurense generate a monophyletic clade and are closely related to M. longipes, P. hedgei, and M. calycinum. According to ITS-based phylogeny, Mattiastrum pulumurense is closely related to Rindera tetraspis, which is seen in the paraphyletic and nested genera Mattiastrum-Paracaryum-Rindera.

Insights into recent discoveries, along with accompanying photographs, ecology, and location specifics in Turkey are presented.

Açar, Mikail; Taşar, Neslihan
This study performed statistical analyses based on chromosome micromor-phology of 18 Centaurea taxa, two of which are endemic. ANOVA, Correlation analy-sis, Discriminant analysis and Cluster analysis were performed to determine the relationships between taxa based on chromosomal features. In addition, according to the data obtained from these analyses, the relationships between taxa and sections were tried to be interpreted. As a result of the analyses, the taxa C. drabifolia Sm. floccosa (Boiss.) Wagenitz & Greuter, C. kotschyi (Boiss. & Heldr.) Hayek var. floccosa (Boiss.) Wagenitz and C. behen L. and C. polypodiifolia Boiss pseudobehen (Boiss.) Wagen-itz were located close to each other. These taxa are located in the same sections in the morphological classification. Besides, in the Discriminant analysis, the taxa of Acrocen-tron, Microlophus, Cheirolepis sections were closely located compared to all other taxa. However, results were not seen to cover all taxa of the sections. This study revealed various chromosomal characteristics of some Centaurea taxa distributed in the Eastern Anatolia. It also performed statistical analyses on these data. While determining the relationships between taxa according to chromosomal characteristics, comparing chromosomal formulas and indices collectively and evaluating the relationships was found to be relatively consistent with morphological classification.

The pollen morphology of eight endemic species of the genus Inula L. (Asteraceae)–I. helenium subsp. orgyalis (Boiss.) Grierson, I. helenium subsp. vanensis Grierson, I. macrocephala Boiss. & Kotschy ex Boiss., I. discoidea Boiss., I. sarana Boiss., I. fragilis Boiss. & Hausskn., I. anatolica Boiss. and I. sechmenii Hartvig & Strid–distributed in Turkey was studied with light microscopy and scanning electron microscopy. We found that the pollen of these Inula taxa are prolate-spheroidal in shape (except in Inula discoidea), with the polar axis ranging from 19.18 to 33.14 µm and the equatorial diameter ranging from 18.54 to 32.92 µm. The pollen grains are tricolporate and their ornamentation is echinate. The exine thickness ranges from 0.87 to 2.07 µm. As this study demonstrates, results of Principal Component Analysis are revealed that some of the pollen characters, such as spine length and width, are significant morphological characters for taxonomic discrimination of the eight endemic Inula taxa. According to cluster analysis, two main groups of examined taxa are constituted.

Genç, Hasan; Yildirim, Bekir; Açar, Mikail; Çetin, Tolga
In this study, a statistical analysis was performed on mitotic metaphase chromosomes of 26 Lathyrus taxa, four of which are endemic. ANOVA, correlation analysis, PCA and cluster analysis were performed to determine the relationships between taxa based on chromosomal criteria. The morphological similarities of plant taxa and chromosomal statistics results may not be always parallel to each other. According to the findings obtained as a result of analysis, the following taxa, which are close to each other were determined: L. hirsutus-L. odoratus, L. brachypterus var. haussknechtii-L. phaselitanus, L. stenophyllus-L. chloranthus, L. gorgoni var. gorgoni-L. nissolia-L. pratensis, L. tuberosus-L. annuus.

Dirmenci, Tuncay; Özcan, Taner; Açar, Mikail; Arabacı, Turan; Yazıcı, Türker; Martin, Esra
Origanum munzurense Kit Tan & Sorger (Sect. Brevifilamentum Ietsw.) was described by Kit Tan & Sorger in 1984, and it is an accepted species related to O. acutidens (Hand.-Mazz.) Ietsw. belonging to sect. Brevifilamentum. It is morphologically intermediate between O. acutidens and O. vulgare L. subsp. gracile (K.Koch) Ietsw., and its type locality lies in the overlap zone between the geographic distributions of these two taxa. We hypothesized that O. munzurense is in fact a hybrid between the two aforementioned taxa and we tested this hypothesis with the general morphology, chromosome features, and nuclear (ITS1–ITS2) and chloroplast (rpl32) DNA sequences of specimens of O. munzurense and its putative parental species, O. vulgare subsp. gracile and O. acutidens. The somatic chromosome number of O. munzurense, O. vulgare subsp. gracile and O. acutidens were counted as 2n = 30. Origanum munzurense presented polymorphic sites in the nuclear ITS region, but the chloroplast markers did not allow us to identify the putative maternal of O. munzurense. Our results suggest that O. munzurense is indeed a hybrid, and its rearrangement as a new homoploid hybrid (O. ×munzurense) would be more accurate. These present results support previous reports for the speciation of Origanum members via hybridization.

Polat, R.; Cakilcioglu, U.; Selvi, S.; Türkmen, Z.; Kandemir, A.
In this study, we comparatively investigated three endemic Salvia species spreading in Erzincan (Turkey) in terms of anatomy and micromorphology. For anatomical investigation, cross sections taken from stems and leaves of the species were examined under light microscope. For micromorphological investigation, epidermal surface and nutlet structure were examined using scanning electron microscopy. The S. euphratica and S. divaricata species were examined anatomically and micromorphologically for the first time, and S. hypargea was examined micromorphologically for the first time. In anatomical examinations, it was seen that stem and leaf structures of the species were similar. In micromorphological analyses, it has been seen that hairiness of the nutlet surface and nutlet ornamentations (verrucate and rugose type) created a difference between the species.
