Polygala seyfegoluensis Dönmez, Uğurlu & Yüzb. (Polygalaceae) is herein described and illustrated as a new species from Kırşehir Province around Seyfe Lake in Central Türkiye. This new species is similar to P. pruinosa and P. supina is distinctly characterized by its prostrate habit, nearly glabrous and smaller flower parts, and an unwinged capsule. A phylogenetic analysis was conducted to show the placement of the new species within selected Polygala taxa using the trnL-F and rbcL markers. Based on the field observation, an evolutionary scenario is proposed for the new species under the driving forces of climate change, the shrinking of …

Trichoderma Indica: A New Species In The Longibrachiatum Clade From Western Ghats, India, Ajay Lagashetti, Sanjay Singh, Paras Nath Singh
Turkish Journal of Botany
Trichoderma is a hyperdiverse genus that comprises species showing a wide range of applications. In this study, we have found an isolate of the genus Trichoderma from a soil sample collected from Vetal Hill, Pune, Maharashtra State, India. The isolate was found to be morphologically distinct compared to other isolates of the Longibrachiatum clade showing longer phialides and shorter conidia. Moreover, a phylogenetic analysis based on combined sequence data of the second-largest nuclear RNA polymerase subunit (rpb2), and the translation elongation factor 1-α (tef1-α) confirmed the uniqueness of the present isolate, showing an independent branch supported by strong bootstrap values …

A New Species Of Parasola Section Conopileae (Psathyrellaceae) From Pakistan, Zaman Khan, Muhammad Awais Arshad, Abdul Rehman Niazi, Abdul Nasir Khalid
Turkish Journal of Botany
The genus Parasola is sparsely documented in Pakistan with almost all of its reports from lowlands or northern areas of the country. In this study, we describe a new species, Parasola cinnamomescens, from the Thal Desert, a subtropical region located in Punjab Province, Pakistan. Evidence from morphology and DNA sequence data encompassing the internal transcribed spacer (ITS1-5.8S-ITS2 = ITS) and D1/D2 domain of the large subunit of nuclear ribosomal DNA (28S) reveals that this species is divergent from all previously known species and confirms its placement in Parasola sect. Conopileae. It is recognized by convex to hemispherical or broadly conical …

Turkish Journal of Botany
Plantago is a cosmopolitan genus with approximately 200 species and various infrageneric classifications have been reported. In this study, the seed morphologies of 19 species of Plantago from Iran were studied and documented in detail using scanning electron microscopy and light microscopy. The studied species were grouped by using statistical analyses such as a minimum spherical cluster method based on Euclidean distance, principal coordinate analysis, and multidimentional scaling. We have described four types based on the seed shape and states of the inner side of the studied seeds: convex- angular type, convex-elliptic type, flat-elliptic type, and concave-elliptic type.

Turkish Journal of Botany
Arundinella stenostachya, a new species, is described and illustrated. It is morphologically similar to A. decempedalis and A. bengalensis, but differs from the former species by the length of panicle branches, type of trichome on nodes and pedicels length, and from the latter in height and diameter of culms, the length and width of leaf blades, pedicels length, and the length of panicles and branches. The new species has been mistakenly identified as A. decempedalis and A. bengalensis. Molecular analyses based on ITS sequences also support A. stenostachya as a distinct species.

Phylogenetic Relationships Among Mexican Species Of The Genus Sechium (Cucurbitaceae), Luis Ángel Barrera Guzmán, Juan Porfirio Legaria Solano, Jorge Cadena Iñiguez, Jaime Sahagún Castellanos
Turkish Journal of Botany
The genus Sechium includes 11 species, which are highly related to the genus Sicyos. Sechium is native to Mesoamerica, but only S. edule and S. tacaco have been domesticated. Sechium edule is the most exploited species of the genus due to its broad phenotypic variability. A total of 68 samples from the species S. chinantlense, S. compositum, S.hintonii and S.edule were evaluated, as well as their respective varietal complexes (albus, nigrum and virens groups), thereby amplifying the loci of mitochondrial DNA (CoxIII), chloroplast DNA (rbcL) and the nuclear ribosomal ITS1-5.8S-ITS2 region. This was done with the aim of establishing phylogenetic …

Notes On The Genus Sauvetrea (Orchidaceae, Maxillariinae), With A Description Of A New Species, Dariusz L. Szlachetko, Natalia Oledrzynska, Monika M. Lipinska
Turkish Journal of Botany
The genus Sauvetrea Szlach. (Orchidaceae) was segregated from Maxillaria sensu lato in 2007. It embraces a group of from 10 to nearly 20 species, all initially defined as Maxillaria sect. Trigonae. Sauvetrea can be easily distinguished from closely related Rhetinantha M.A.Blanco by the lip callus. During the revision of the materials stored in AMES we came across specimens collected by Vargas in Peru, which were initially identified by Schweinfurth as Maxillaria brachypetala Schltr. We compared Vargas's discovery with the protologue of the latter species and other Sauvetrea, but it does not fit the description of any genus representatives known so …

Turkish Journal of Botany
The actual variation and specific diversity of Neotropical Draconanthes aberrans is evaluated based on morphological data. As recognized in this paper D.aberrans complex includes a total of 6 species, 3 of which are described here. New combinations are proposed for Lepanthes prionota and L. trachysepala. Two species, including D. aberrans, are lectotypified. The previous incorrect typifications are discussed. Each of 6 species is morphologically characterized. The perianth segments of all discussed taxa are illustrated. The key to identification of species belonging to the Draconanthes aberrans complex is presented together with the comparative morphology of studied taxa.

Comparative Anatomical Studies In Relation To Taxonomy Of Sedum S.L. (Crassulaceae) In Iran, Maryam Mohammadi Shahrestani, Marzieh Beygom Faghir, Mostafa Assadi
Turkish Journal of Botany
This study aimed to characterize the stem, peduncle, and leaf anatomy of 22 species of Sedum senso lato distributed in Iran. The results showed that the presence of tanniniferous storage cells in stems and leaves, distinct xylem vessels in stems, and the shape of peduncle cross sections, were taxonomically informative evidence, and isolated Phedimus from the other studied taxa of Sedum s.l. , whereas hairy leaves and peduncles containing starch storage cells were identified as Prometheum and Hylotelephium respectively. In addition, the current anatomical evidence confirmed the alliance of 2 sections of Sedum and Epeteium within Sedum sensu stricto. The …
