Porophyllum riparium, a new species of the genus Porophyllum, is described. Morphological details, illustration, geographical distribution, and photographs in its natural habitat are provided. This new species occurs in the northwest region of Argentina, in Salta, Jujuy and Tucumán Provinces, in the Yungas biogeographical province. It is usually found on rocky and sandy soils, as well as along riverbanks. Porophyllum riparium is characterized by being an annual or short-lived perennial, glaucous, odoriferous, monoecious herb, 15–80(–130) cm tall, with sessile or attenuate into a pseudopetiole, linear-elliptic leaves with submarginal and subapical semi-pellucid oil cavities, lemon-colored infundibuliform corollas and exserted brownish anthers. Additionally, female plants of Porophyllum cabrerae were documented for the first time, photographs and descriptions of their female florets are included. Also, a key to identify northwestern species of Porophyllum is provided.

Reevesia lofouensis (Malvaceae) from Guangdong, China, has been treated as a synonym of R. thyrsoidea recently. However, R. lofouensis differs from R. thyrsoidea in having densely yellowish stellate-tomentose branchlets and petioles, relatively large inflorescence with more flowers. Therefore, R. lofouensis is reinstated as a distinct species. An emended description of R. lofouensis with a detailed description of the flower is also provided here.
中国广东的 Reevesia lofouensis（锦葵科）最近被当作 R. thyrsoidea 的异名。然而，R. lofouensis 与 R. thyrsoidea 的区别在于小枝和叶柄密被淡黄色星状绒毛，花序相对较大，花朵较多。因此，R. lofouensis 被恢复为一个单独的种。这里还提供了 R. lofouensis 的修订描述以及花的详细描述。

Molecular phylogenetic reconstruction of Calea demonstrated that the circumscription of infrageneric groups should be altered or that the description of new sections and series is necessary for recognition of monophyletic taxa. One of these infrageneric groups is C. ser. Candolleanae, newly proposed here. Previously recognized as an informal complex, this group comprises eight species that occur exclusively in Brazil. Most of its species can be characterized by long-pedunculate radiate capitula, campanulate involucre, epaleaceous or partly paleaceous receptacle, strigose or glabrous cypselae, and pappus scales 0.1–1.5 mm long. In order to improve our understanding of this series, we generated a nomenclatural synopsis, revising protologues and type material. We propose 6 lectotypifications and 1 neotypification. In addition, we record new Brazilian state level occurrences for three species: C. angusta (Alagoas), C. gardneriana (Maranhão), and C. martiana (Bahia).

Traditionally, species delimitation based on morphological and distributional evidence often leads to over- or underestimation of species diversity. The primary distribution area of Cycas debaoensis includes two habitats, which were initially published as two separate species, i.e., C. debaoensis in the karst habitat, and C. panshuiensis, which was originally published as Cycas gracilis Y.Y. Huang, Y.C. Zhong et Z.F. Lu, in the sand habitat. However, field investigations and population sampling in these two habitats revealed a certain degree of morphological transition and variation among the populations. Subsequent population genetic analysis showed minimal genetic differentiation among the populations in the two habitats, suggesting that they should be merged as a single species. Additionally, the typification of the name C. debaoensis is also discussed.
传统上，基于形态和分布证据的物种划分往往会导致物种多样性被高估或低估。德保苏铁（Cycas debaoensis）的主要分布区包括两个生境，最初被作为两个独立的物种发表，即岩溶生境中的德保苏铁（C. debaoensis）和沙生生境中的盘水苏铁（C. panshuiensis），后者最初被作为黄永玉、钟永中等人和陆志飞等人发表的苏铁（Cycas gracilis Y.Y. Huang, Y.C. Zhong et Z.F. Lu）。然而，在这两种生境中进行的野外调查和种群取样发现，种群之间存在一定程度的形态过渡和变异。随后的种群遗传分析表明，这两个生境中的种群遗传差异极小，建议将它们合并为一个物种。此外，还讨论了 C. debaoensis 这一名称的类型化问题。

The ITS and cpDNA sequences were obtained for three taxa of the family Phytolaccaceae, viz. Rivina bengalensis S.C.Srivast. & T.K.Paul, R. humilis L. var. humilis, and R. humilis var. bracteata D.Maity, Sonia Mitra, Manasi Mandal & Maiti. The MLtree strongly supports the Rivina humilis clade, which includes R. bengalensis and R. humilis var. bracteata. The synonymization of R. bengalensis is supported by both molecular and morphological data. The accessions of Rivina humilis var. bracteata group together in the R. humilis clade, but the results also show inter-population variation, which primarily supports the varietal status of the taxon. The broadly oblanceolate bracts which is abruptly narrowed from middle or above middle into a long subulate to narrowly triangular, acuminate apical lobe make the variety distinct from typical R. humilis. The combined rbcL and trnH-psbA dataset reveal congruent result for the sequenced Rivina spp. Present study is the first report on molecular systematics of R. humilis from India.

Amanita amplivelata is introduced as a new species, based on numerous collections from geographically distant areas of Europe and the Near East (Bulgaria, the Czech Republic, France and Türkiye). This new species is likely ectomycorrhizal with Populus spp. in natural poplar stands, urban settings, and plantations. Detailed description and illustrations of its morphological features are presented. Phylogenetic analysis of nrITS and combined nrITS, nrLSU and TEF-1α sequences placed it in a separate stirp in Clade 5 of section Vaginatae. The ample, saccate volva with a peculiar microscopic architecture confirms relatively close phylogenetic relationships with A. crocea and A. dryophila. The distinction of the new species from other phylogenetically related or morphologically similar taxa is outlined.
Amanita amplivelata 是根据从欧洲和近东地理位置遥远的地区（保加利亚、捷克共和国、法国和土耳其）采集到的大量样本作为一个新物种引入的。这种新物种很可能在自然杨树林、城市环境和种植园中与杨属植物发生外生菌根关系。本文对其形态特征进行了详细描述和说明。通过对 nrITS 以及 nrITS、nrLSU 和 TEF-1α 的组合序列进行系统发育分析，将其归入阴道虫科第 5 支系中的一个独立支系。丰满、囊状的阴道具有奇特的显微结构，这证实了它与 A. crocea 和 A. dryophila 之间相对密切的系统发育关系。概述了该新种与其他系统发育相关或形态相似类群的区别。

During an investigation into species diversity of lignicolous freshwater fungi from the plateau lakes in Yunnan Province, China, a hyphomycetous fungus was collected from Dianchi Lake. The new isolate was placed in Appendopyricularia as a sister taxon of Appendopyricularia juncicola within Barbatosphaeriaceae based on the phylogenetic analysis of combined ITS and LSU sequence data. The fungus is characterized by acrogenous, fusoid, guttulate conidia that are 3–4 septate and have a flexuous central apical appendage. It exhibits more pronounced guttulate appendages and more prominent denticle sporulation structure. Therefore, Appendopyricularia guttulata is introduced as a new species based on morphological characteristics and phylogenetic evidence. The detailed description and illustrations of the new species are provided, as well as the morphological comparison with similar taxa.

The rate at which people are introducing species to formerly uninhabited places shows no signs of slowing down. Wild plants can roam freely across international borders. From September 2021 to June 2023, 45 field excursions were made to Egypt’s southern Nile Islands in the Aswan Governorate to undertake vegetation surveys. Depending on the literature reviewed and herbaria consulted during this study, three plant taxa, as well as one additional genus (Macroptilium), found during these field excursions were not previously recorded in the Egyptian Flora. These new records are Acanthospermum hispidum (Asteraceae), Geranium carolinianum (Geraniaceae), and Macroptilium atropurpureum (Fabaceae). These plants are classed as noxious weeds that harm agriculture. A complete description, occurrence and distribuion maps, plant photos and illustrations are provided. This study underlines the importance of carrying out extensive and ongoing research on the flora of Aswan’s Nile Islands to have a better knowledge of flowering plant distribution patterns. In addition, it might be regarded as a great starting point for expanding floristic knowledge of this interesting territory and its surroundings.

Mallomonas denticulata was described by Matvienko in the 1940s, however the ultrastructure of its scales and bristles remained unknown, so the species was considered to be dubious. Mallomonas asmundiae (≡M. cratis var. asmundiae) is a rather rare and widely accepted species but this name is invalid. In this report we discuss the similarity in the scale and bristle morphology between these two species and designate lectotype and epitype for M. denticulata. An emended description is provided.
