Meibomia bakeriana Kuntze is the earliest legitimate species name available for Baker's illegitimate Desmodium rotundifolium. Alysicarpus rotundifolius Dalzell ex Prain and Desmodium ritchiei Sanjappa are illegitimate superfluous names for the same species, whereas Desmodiastrum rotundifolium (A.Pramanik and Thoth.) Sanjappa cannot be used because of the lack of priority. H. Ohashi and K. Ohashi published an isonym in Desmodiastrum. The new combination Desmodiastrum bakerianum (Kuntze) Kottaim. is proposed here in order to provide a correct name for the species occurring in India.

Psammogeton hirsutus Bhellum and Magotra (Apiaceae), a novel species collected from the lowlands of Jammu and Kashmir, north-west India's subtropical region, is described and illustrated. Psammogeton hirsutus resembles one its close relatives P. canescens and P. shivalikense; however, it differs significantly in terms of the plant being hirsute, sheaths of leafbases, ciliate peduncle degree of pubescence, bracts and bracteoles, and fruit shape. We provide data on phenology, distribution map, a comparison of species with comparable morphologies, and a key to closely related species.

The lack of remediation of inactive mine sites is a serious global concern, as they pose risks to the environment, human health, and safety. The potential of Dianthus sylvestris subsp. sylvestris to remediate post-mining sites contaminated with copper (Cu) at high altitudes, which is a challenging task for most management strategies, was explored in this study. More than 1300 mg Cu kg−1 in shoots were found in plants collected at the Monte Avanza legacy mine site (Alps). However, it is unclear whether this is due to hyperaccumulation or foliar contamination. To address this gap, field samples were washed with two different protocols, and a controlled Cu-tolerance test was conducted. While very high Cu concentrations, exceeding the Cu hyperaccumulation threshold of 300 mg kg−1, were found in samples washed with water, results for the plants cleaned with a more rigorous approach with EDTA suggested Cu exclusion strategy. Under controlled conditions, the plant showed Cu hypertolerance but did not hyperaccumulate Cu. Thus D. sylvestris presents a Cu exclusion strategy rather than hyperaccumulation potential, making it a suitable candidate for Cu phytostabilization at high altitude legacy mine sites. The study emphasizes the need for experiments under controlled conditions when assessing the phytoremediation potential.

A new species, Fimbristylis pachmarhiensis (Cyperaceae), is described and illustrated from Pachmarhi Biosphere Reserve of Hoshangabad district, Madhya Pradesh, India. This new species bears resemblance to its closest morphological relatives, F. aestivalis and F. griffithii, but differs from both by a combination of characters, primarily including its slender culm, exceptionally lax inflorescence, cylindrical spikelets, triquetrous structure, and the presence of fine hairs covering the entire length of the style. Additionally, the achenes of this species exhibit sparse tuberculation and have a depressed apex. A detailed description, phenology, distribution, IUCN conservation status, a comparative analysis contrasting F. pachmarhiensis with its closely related species, relevant taxonomic notes and colour photographs are provided.

Petrosaviales is an early diverging monocot order that includes only two genera with distinct nutritional modes, namely the autotrophic Japonolirion and mycoheterotrophic Petrosavia. A rare serpentine plant endemic to Japan, Japonolirionosense is the only species of this genus. Although Petrosavia species are known to produce seeds by autonomous self-pollination, the mating system and flower visitors of J. osense remain unknown. In this study, the pollination biology of J. osense was investigated on a serpentine slope in northern Hokkaido, Japan. Pollination experiments suggested that J. osense predominantly depends on cross-pollination by insect pollinators for seed production. Ants and dipterans were the main flower visitors to this species. This study showed that the two genera in Petrosaviales with distinct nutritional modes also have contrasting mating systems, which provides insights into the evolution of pollination biology in this early diverging monocot order.
矮牵牛属（Petrosaviales）是早期分化的单子叶植物纲，只包括两个具有不同营养模式的属，即自养型的 Japonolirion 和菌根营养型的 Petrosavia。Japonolirion osense 是日本特有的稀有蛇麻藤植物，也是该属的唯一物种。虽然已知 Petrosavia 物种能通过自主自花授粉产生种子，但 J. osense 的交配系统和访花者仍不为人知。本研究在日本北海道北部的一个蛇形山坡上调查了 J. osense 的授粉生物学特性。授粉实验表明，欧鼠李主要依靠昆虫授粉者的异花授粉来生产种子。蚂蚁和双翅目昆虫是该物种的主要访花者。这项研究表明，石蒜科的两个属具有不同的营养模式，它们的交配系统也截然不同，这为研究这一早期分化的单子叶植物的授粉生物学进化提供了深入的见解。

An ongoing taxonomic work on Phyllanthus subsect. Phyllanthus, resulting from the analysis of protologues and the study of approximately 2000 collections, including all types, historical collections, and observations in the field, led us to describe two new species (P. lobatus and P. platystigma), and to propose the synonymization of P. mimicus and P. bolivianus under P. niruri, as well as establish a lectotype for P. bolivianus. For both new species, we provide, descriptions, illustrations, preliminary conservation status, flowering and fruiting periods, environmental preferences and images in their habitat. In addition, they are compared with morphologically similar congeners and their systematic position is discussed.

A new powdery mildew species, Erysipheneelamensis, was found on Celtis eriocarpa in Azad Jammu and Kashmir, Pakistan. The identification was based upon morpho-anatomical features and results of a molecular sequence analysis. This species is morphologically distinguished from phylogenetically allied Erysiphe species by having chasmothecia with fewer, shorter appendages and a small number of asci and ascospores. A phylogenetic analysis of the nrDNA of ITS region of E. neelamensis supports the involvement of a novel species of the genus Erysiphe. The new species is described, illustrated and compared with all allied species, along with a phylogram showing its inferred phylogenetic position.

Jurinea stenocarpa, is described as a new species based on morphological characters. This species is a mountainous Irano-Turanian element distributed in the north-west of Iran, –the Azarbaijan region. Specimens of this species were collected from Aqdagh (type location) and Talesh Mountains in Ardabil Province, Pir-Saqqa Mountain in Eastern Azarbaijan Province. The taxonomic position of the new species is assessed using sequence data from the nuclear ribosomal ITS region, and the findings are discussed based on a morphological background as well. The new species is morphologically close to its sympatric species, J. heterophylla by having linear-lanceolate simple and more or less entire leaves, but differs mostly in the form of inflorescence and shape and status of phyllaries. The new species also has similarities to its allopatric species J. monocephala, mainly by having semi-globose involucre and scapose stems, but differs in plant indumentum, the shape of phyllaries and features of achenes and size of pappus rays. Description, photos and a distribution map for the new species and closely related species are presented.
