Achene Micromorphology Of The Genus Potentilla L. (Rosaceae) In Iran And Its Systematicapplication, Samira Sadeghi, Marzieh Beygom Faghir, Farideh Attar, Ali Alaami Jan 2021

Achene Micromorphology Of The Genus Potentilla L. (Rosaceae) In Iran And Its Systematicapplication, Samira Sadeghi, Marzieh Beygom Faghir, Farideh Attar, Ali Alaami

Turkish Journal of Botany

Achene micromorphological evidence belonging to 32 species of Potentilla from Iran were studied using scanning electron microscopy (SEM). Multivariate analysis was used to estimate the potential contribution of the quantitative and qualitative traits to the species relationships. Based on the present results, the achene micromorphological traits exhibited considerable variations. The SEM observations revealed 4 types of achene shapes, 4 main types and 6 sub types of surface patterns, 3 types of wax, 8 types, 15 subtypes, and 4 categories of sculpturing, 2 types of anticlinal cell boundaries, and 3 types of outer periclinal walls. In addition, the results demonstrated variations …


Phylogenetic Relationships Among Mexican Species Of The Genus Sechium (Cucurbitaceae), Luis Ángel Barrera Guzmán, Juan Porfirio Legaria Solano, Jorge Cadena Iñiguez, Jaime Sahagún Castellanos Jan 2021

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 …

Anthemis ekicii (Asteraceae) is described and illustrated as a new species from Tuz Lake in Aksaray Province in Central Anatolia. The new species belongs to the section Anthemis, and it is closely related to A. pauciloba var. pauciloba, from which it differs in stem, leaves, and capitulum features. Diagnostic characters, description, detailed illustrations, ecology, IUCN conservation status, and pollen and seed morphology are presented in this study.


Nomenclatural And Taxonomic Notes On Some Stachys Taxa (Lamiaceae), Özal Güner, P. Pablo Ferrer-Gallego Jan 2021

Nomenclatural And Taxonomic Notes On Some Stachys Taxa (Lamiaceae), Özal Güner, P. Pablo Ferrer-Gallego

Turkish Journal of Botany

Stachys glechomifolia (Lamiaceae), previously included under S. mardinensis as a synonym, is resurrected in this work based on extensive field and herbarium studies. In addition to its distribution in Turkey, S. mardinensis has firstly been recorded from Iran. Furthermore, the lectotypes of S. fragillima, S. graveolens, and S. kurdica var. brevidens are designated in this study. An expanded description and distribution map of S. glechomifolia, and some taxonomic notes on S. graveolens, S. fragillima, S. mardinensis, and S. nephrophylla are also reported.


Phylogeny And Taxonomy Of A Novel Species Of Pseudocercospora From India, Archana Singh, Paras Nath Singh, Gopal Nath, Nawal Kishore Dubey Jan 2021

Phylogeny And Taxonomy Of A Novel Species Of Pseudocercospora From India, Archana Singh, Paras Nath Singh, Gopal Nath, Nawal Kishore Dubey

Turkish Journal of Botany

A new species of Pseudocercospora is described causing leaf spot disease on Crotalaria assamica from India. The identity of isolate was based on asexual morphs, cultural characteristics and phylogenetic analyses of partial nuclear ribosomal 28S large subunit and complete internal transcribed spacer rDNA sequence data with high statistical support value. Morphologically this species has characters similar to allied species in genus Pseudocercospora but differs in having catenate and branched conidia. Phylogenetic analysis using LSU and ITS reveals it a new species of >i>Pseudocercospora (Capnodiales, Mycosphaerellaceae).


A New Asperula L. (Rubiaceae) Species From Gypsum Steppes Of Çankırı Province In Turkey, Bi̇lal Şahi̇n, Mehmet Sağiroğlu, Bi̇rol Başer Jan 2021

A New Asperula L. (Rubiaceae) Species From Gypsum Steppes Of Çankırı Province In Turkey, Bi̇lal Şahi̇n, Mehmet Sağiroğlu, Bi̇rol Başer

Turkish Journal of Botany

Asperula cankiriense B.Şahin & Sağıroğlu, a new species discovered in the central Anatolian region of Turkey (Çankırı), is described herein. A. cankiriense is similar to Asperula bornmuelleri Velen. However, A. cankiriense differs mainly in its habitus, stem, leaves, and inflorescence features. In this study, the diagnostic morphological features, distribution, habitat and ecology, etymology, conservation status, and taxonomic features of the new species are discussed. Additionally, pollen micromorphological characteristics of A. cankiriense and A. bornmuelleri are examined and compared using light microscopy (LM) and scanning electron microscopy (SEM) analyses. The pollen grains are subprolate, aperture type 6?7 or rarely 8 zonocolpate …


A New Species Of Foliicolous Lichenized Fungi From Southwest China: Calopadia Ruiliensissp. Nov., Hai-Xia Wu, Wei-Bin Ren, Xin-Hao Li, Zi-Xiang Yang Jan 2021

A New Species Of Foliicolous Lichenized Fungi From Southwest China: Calopadia Ruiliensissp. Nov., Hai-Xia Wu, Wei-Bin Ren, Xin-Hao Li, Zi-Xiang Yang

Turkish Journal of Botany

Calopadia ruiliensis, found on living leaves in southwest China, is described as a new species, based on morphology and phylogenetic analysis. It is characterized by a foliicolous thallus with yellow greenish to creamy yellow color, rounded apothecia with nonpruinose to thinly pruinose disc, a dark olive-green hypothecium and black-brown subhymenium, and 1-spored asci producing muriform ascospores. Phylogenetic analysis of LSU sequence data shows that the new species clusters in the genus Calopadia with high bootstrap support. The new species is compared with closely related and similar species of Calopadia and a comprehensive description and micrographs are provided.

Turkish Journal of Botany

Astragalus nurhakdagensis, a new species from the south of Turkey was described, illustrated, and compared to the closest taxa Astragalus hirsutus, A. dumanii and A. cataonicus from which it is set apart by a longer calyx length (13-14 mm) and calyx teeth (7-9 mm, longer than tube), white corolla colour, longer bracts (13-15 mm) and black hairy stripes below the stem nodes. In A. hirsutus, the calyx length (6-10 mm) and calyx teeth are much smaller (2-3 mm long, shorter than tube), with yellow corolla colour and without black hairy stripes. It also differs from A. dumanii with its longer …
