The genus Nymphoides is a freshwater aquatic dicot represented by two species in Iran. Based on our current regional taxonomic revision of this genus, we recognize Nymphoides cristata, previously identified as Nymphoides indica in Flora Iranica. However, these species are easily distinguished from each other by having crested petal lobes in the latter. We investigated the morphology and anatomy of Nymphoides cristata and Nymphoides peltata. The most important morphological features for differentiation between these species are corolla color and inflorescence type. The anatomy of cross-sections of leaf, petiole, stem and the surface sections of leaf were studied. The following characters were found to be taxonomically informative: the presence of stellate, polyramous and ramiform foliar sclereids as well as the presence of astrosclereids in petioles and stems of both examined taxa, while spheroidal sclereids are only observed in the stems of Nymphoides peltata.

The fern genus Pseudocyclosorus (Thelypteridaceae) from China and the Pan-Himalaya region is revised based on morphological study. Reduced basal pinnae, angles between costule and costae, and glands/hairs on abaxial surfaces/indusia are considered as the most diagnostic morphological characters for species delimitation. Genus Trigonospora was excluded from genus Pseudocyclosorus. This segregation is supported by multiple morphological features. Eight species were recognized here, namely Pseudocyclosorus tylodes, P. pseudofalcilobus, P. falcilobus, P. subochthodes, P. stramineus, P. ornatipes, P. esquirolii and P. canus. Twenty-one names were reduced as new synonyms. One name (P. duclouxii) was considered a dubious species. A key to these eight species, their descriptions, spore morphology and distribution map of each species are given.         Pseudocyclosorus stramineus was a long overlooked species, which has always been misidentified as other similar species, and was wrongly reduced as a synonym of P. duclouxii. Here based on morphology characters, the identity of P. stramineus as a species was reclaimed. A more detailed description with photographs and illustrations, and its whole distribution range are given here.

Within the framework of a taxonomic revision of subfamily Urgineoideae, we here describe a new genus from south-eastern South Africa. Sagittanthera gen. nov. is at first sight related to Rhadamanthus and Tenicroa, but it can be clearly differentiated by the presence of bracteoles and the anthers connate to form a cone-like structure dehiscing by minute apical pores. This genus is based on Rhadamanthus cyanelloides, an enigmatic species occurring in the Eastern Cape Province of South Africa. It was described on the basis of incomplete material. Recently, Drimia cremnophila and D. mzimvubuensis, two species that match the diagnostic characters of the new genus, were described from the same region. A complete description is presented for Sagittanthera, and data on morphology, ecology, and distribution are also reported. Two species are accepted in this genus, and the necessary combinations are stated. Furthermore, we demonstrate that pollen is released by vibration. This fact together with morphological features of the androecium clearly evidence that buzz pollination occurs in this new genus.

Ptilohyaleexplorator (formerly Parhyaleexplorator), described by Arresti (1989), can be considered to be a synonym of west-Atlantic Ptilohyalelittoralis (Stimpson, 1853), based on morphological observations of paratypes and specimens recently collected in the type locality of Ptilohyaleexplorator. The first collections of Ptilohyalelittoralis, from the eastern Atlantic were from the port of Rotterdam (The Netherlands) in 2009 and later in Wimereux, Opal Coast (France) in 2014; however, the synonymy of Ptilohyaleexplorator with Ptilohyalelittoralis backdates to the first European record of Ptilohyalelittoralis in 1985 at La Vigne, Bay of Arcachon (France). This indicates that Ptilohyalelittoralis has been established along European Atlantic coast for many years. An assessment of the nominal valid species belonging to the genus Ptilohyale was carried out and a comparison between the Atlantic Ptilohyalelittoralis and the very similar Mediterranean hyalid species, Parhyaleplumicornis, is presented based on morphological features and distribution. Due to the invasive ability of Ptilohyalelittoralis, a comparison between the two species is necessary.

The genus Asteralobia (Diptera, Cecidomyiidae, Asphondyliini, Schizomyiina) was erected by Kovalev (1964) based on the presence of constrictions on the cylindrical male flagellomeres. In the present study, we examine the morphological features of Asteralobia and Schizomyia and found that the male flagellomeres are constricted also in Schizomyiagaliorum, the type species of Schizomyia. Because no further characters clearly separating Asteralobia from Schizomyia were observed, we synonymize Asteralobia under Schizomyia. Molecular phylogenetic analysis strongly supports our taxonomic treatment. We describe five new species of Schizomyia from Japan, S.achyranthesae Elsayed & Tokuda, sp. n., S.diplocyclosae Elsayed & Tokuda, sp. n., S.castanopsisae Elsayed & Tokuda, sp. n., S.usubai Elsayed & Tokuda, sp. n., and S.paederiae Elsayed & Tokuda, sp. n., and redescribe three species, S.galiorum Kieffer, S.patriniae Shinji, and S.asteris Kovalev. A taxonomic key to the Japanese Schizomyia species is provided.

Polygonatum Miller (1754, without pagination) (Asparagaceae) is a relatively large genus containing approximately 60 taxa (Chen & Tamura 2000). The majority of species are eastern Asian (Jeffrey 1980, Chen & Tamura 2000). Phyllotaxy, cytology, and filament morphology have been recognized as important in delimiting species (Suomalainen 1947, Tamura 1990, 1991, 1993). Specimens of an anomalous Polygonatum collected by J.F. Maxwell from northern Thailand, Doi Inthanon have a general affinity to P. punctatum Royle ex Kunth (1850: 142) and have been reported as that species (Tamura 1993, Maxwell 1998), but differ in their emaculate white and longitudinally ridged perigone. Cultivated material from the same locality (BSWJ6599, Figs. 1–2) provides clear observation of the differences that are not as apparent on pressed specimens. It differs in several morphological features from P. punctatum: stem characters; phyllotaxy; leaf shape; inflorescence type and position; perigone color; and filament size, orientation, and morphology. The combined morphological differences and non-contiguous distributions of P. costatum in comparison to P. punctatum support its recognition as a new species, thus far documented only from the highest elevation in northern Thailand.

The article gives an overview of the small and archaic tribe Baphieae (Fabaceae, Fabales). The study is devoted to the taxonomic revision of the Baphieae tribe and and the phylogenetic relationships within the group based on the morphological, anatomical, palynological and molecular characteristics. It was carried out on the basis of studying about 5,000 herbarium leaves in 12 European and African botanical institutions. The study was performed using the morphological-geographical and molecular-phylogenetic analysis methods. The article provides information on the morphological features of the species included in the tribe, their geographical distribution and chemical composition. The results of phylogenetic analysis have been presented. According to it, it can be argued that the tribe Baphieae is a monophyletic group occupying a relatively isolated position among the subfamily of moths, based on morphological and molecular characteristics. The proposals for a new structure of the tribe have been made. The identification of several phylogenetic lineages within the tribe and the basal position of the genus Dalhousiea have been substantiated. Further studies have been identified.

Punica Granatum L

The issues of the taxonomy of the olygotypic family Punicaceae Bercht. et J. Presl are concerned. The study of the family in 2005–2017 indicates that the differences between two species Punica granatum L. and P. protopunica Balf. f. are insufficient to treat P. protopunica, an endemic of the Socotra Island, as a separate genus. The range of the variability of morphological features and caryological data suggest advisability to preserve the both species in the genus Punica L. The family Punicaceae, in its turn, is often considered as the subfamily Punicoideae Luerss. within the family Lythraceae J. St.-Hil. The necessity to preserve Punicaceae in the range of family is determined by its distinction in the combination of several important morphological features (such as structure of fruits, seeds, position of the cotyledons, etc.) from the members of relative families.

Abstract The aim of this paper is to investigate morphological, anatomical, palynological, fruit and seed micromorphological properties of Hedysarum pannosum (Boiss.) Boiss. A detailed description of the species is reported for the first time in this study. The morphological features of the species have been compared with the results of previous investigations. Anatomical studies have been carried out on cross-sections of roots, stems, leaflets and petioles. The anatomical results show that the plants have secondary growth roots, protruding stems, amphistomatic and equifacial leaves with tannin, triangular shaped petioles. Hedysarum pannosum pollen are tricolpate, prolate and pollen exine ornamentation is reticulate. Fruits have trichomes on their setae and tomentose trichomes have papillae. Seeds are reniform and they have rugolo-reticulate ornamentation.
