ABSTRACT Taxonomic and floristic studies in the state of Rio de Janeiro allowed the rediscovery of Miconia gigantea, an endemic species to the Atlantic Forest, until recently known only from the type specimen, collected over 100 years by A.F.M. Glaziou. We present an amended and detailed description of M. gigantea, providing characteristics of the flowers, fruits and seeds, in addition to illustrations, comments about taxonomic affinities with closely related species, the presently known distribution together with new occurrence records, and the conservation status.

Impatiens benthamii Steenis (Balsaminaceae) is re-collected from the type locality, Khasi Hills, Meghalaya, India, almost 60 years since it was last collected. The history and nomenclatural complexity of this little-known endemic species is discussed. A clarification of the distributional range of the species is given due to previous erroneous reports. To facilitate its proper identification, a detailed description based on live materials and colour photographs is provided. The characters of Impatiens benthamii are compared to those of closely related species. A lectotype is designated.

Abstract The genetic resources and biological diversity of countries are very important. Biodiversity and genetic resources should be protected, especially as endemic species. In this concept, DNA barcoding studies are an effective way to identify an unknown taxon and protected the biodiversity of a country. Astragalus argaeus and A. stenosemioides are narrow endemic species from Mt. Erciyes, Turkey. To determine its phylogenetic relationships and DNA barcoding, sequence data from the chloroplast DNA (matK region) were analyzed by parsimony, maximum likelihood, and Bayesian methods. In this study, A. argaeus, A. stenosemioides samples, and 23 sequences from GenBank, including a closely related species were performed. The phylogenetic analysis showed that the matK gene region could clearly distinguish A. argaeus and A. stenosemioides from its closely related species. DNA barcoding surveys can contribute to taxonomic and biodiversity research, various molecular ecology, and population genetics studies. Also, it is possible to determine the species by separating the matK DNA gene region, which is one of the molecular characters, and A. argaeus and A. stenosemioides have been successfully barcoded for the first time; therefore, it has been shown that this gene region can be used for barcoding.

AbstractIn this second part of a revision of the genus Loboptera Brunner v. W., the Moroccan species are treated. In addition to the 6 species already known (L. alluaudi Chopard, L. decipiens (Germar), L. irregularis Chopard, L. maroccana Bolívar, L. minor Bolivar, L. truncata Chopard), 5 new species and 1 new subspecies are described (L. cuneilobata, L. cryptofoveata, L. foveolata, L. glandulifera, L. ovolobata, L. minor semicirculolobata). Only one of the species (L. decipiens) has a wide distribution; the other species appear to be endemic to Morocco except for L. ovolobata which also reaches into western Algeria. The endemic species (incl. L. ovolobata) form a well defined group of closely related species (the maroccana group). The characteristics of the maroccana group are described. A key for the identification of the Moroccan species is also given.

Verbascum ifranensis Khamar H. & al. is described as a new endemic species from the Middle Atlas Mountains in Morocco, based on morphology of vegetative and reproductive organs. We provide notes on its delimitation from closely related species, especially V. dentifolium Delile and V. lychnitis L. Comparison of ITS sequences and a distance matrix analysis is provided for V. ifranensis and the two closely related species to add molecular evidence to the morphological findings. In addition the geographical distribution and the conservation status are assessed.

Extensive botanical explorations focused on the taxonomy and phylogeny of the genus Manihot in the Cerrado biome permitted the finding of three new species restricted to Serra do Tombador in the municipality of Cavalcante, Goiás state, of Brazil. Manihot ebracteata, Manihot purpurea and Manihot tombadorensis, are described and illustrated. Morphological characteristics of the new taxa, relationships with closely related species, as well as comments on ecological aspects and natural distribution for each species, are provided.

Meiosis in hybrids derived from crosses of Secale ancestrale Zhuk. with related species is highly irregular: chiasmata fail to terminalize; numerous AI and AII bridges form but are usually unaccompanied by fragments; acentric fragments without true bridges are left behind at AI and AII; numerous micronuclei are produced at TII. These anomalies appear to be the result of genetically induced subchromatid exchanges. This appears to be a mechanism established by natural selection for reproductive isolation, thereby permitting this narrowly endemic species to successfully continue in sympatric association with closely related species.

In this paper we analyzed environmental differentiation of closely related species from the Merodon ruficornis group. By applying principal component analysis (PCA) and environmental niche modelling (ENM)-based techniques, we estimated the level of niche divergence of closely related species. Our results indicate that ecology has an important role in the diversification process in related species from the M. ruficornis group. Distribution patterns of all analyzed species are mainly affected by the limiting effects of the temperature of the coldest quarter and month, as well as by the precipitation of the wettest and driest quarters. Our results demonstrated that among all related species, with the exception of M. ovaloides, overall or partial divergence in environmental space is present. Importantly, the results indicate that the environmental niches of all endemic species are restricted to smaller parts of the environmental space. In the case of niche overlap, the niches of endemic species are placed along the border of the realized niche of the widespread related species. For species in which distribution is not limited by geographical barriers, environmental preferences could be considered as limiting factors for further expansion, as in the case of M. alexandri, a lowland species with very strict climatic adaptations. Knowledge about the environmental factors that might influence the diversification process can provide an explanation for the high diversity in other Merodon species groups.
