Based on molecular and morphological evidence, a new species of Salvia (Lamiaceae), Salvia glabrifolia D.G. Zhang & X.J. Long, from Hunan Province, China, is described and illustrated. Salvia glabrifolia is morphologically similar to S. cavaleriei var. simplicifolia, S. daiguii, and S. cavaleriei var. cavaleriei but is distinct by its glabrous stem, petioles, veins, inflorescence axis, leaf margin repand, and glossy and subleathery leaf texture. Maximum likelihood (ML) analyses of the whole plastome dataset strongly supported S. glabrifolia as a sister to the S. japonica-S. liguliloba clade. Moreover, the chromosome number of S. glabrifolia, 2n = 16, is the same as other species in S. chinensis group.
基于分子和形态学证据，描述并说明了产自中国湖南省的丹参（唇形科）的一个新种：Salvia glabrifolia D.G. Zhang & X.J. Long。Salvia glabrifolia 在形态上与 S. cavaleriei var.对整个质体数据集的最大似然法（ML）分析强烈支持 S. glabrifolia 是 S. japonica-S. liguliloba 支系的姊妹。此外，S. glabrifolia 的染色体数目为 2n = 16，与 S. chinensis 群中的其他物种相同。

Long-term field surveys within Tunisian dorsal revealed the recollection of the poorly known North African endemic Onobrychis kabylica and O. conferta subsp. conferta. Two new varieties of O. conferta subsp. conferta are described and illustrated, a key to recognize the two varieties of the species and a distribution map of both taxa are included. IUCN Red List assessment shows that the species should be considered Critically Endangered and requires the implementation of immediate appropriate measurements to ensure their conservation.

The peak Pico de São Tomé on the island of São Tomé (São Tomé and Príncipe, Gulf of Guinea) is a locality where many specimens that became types of vascular plant names were collected during colonial times. Determining the routes the collectors took to ascend the peak will help determine some collecting localities. Gustav Mann was the first collector to explore the region; his itinerary is analysed and mapped based on his correspondence. The itineraries of ten further expeditions that ascended the peak are analysed. Collections that became types of vascular plant species names are recorded.
圣多美岛（几内亚湾，圣多美和普林西比）上的圣多美山峰（Pico de São Tomé）是殖民时期收集许多标本的地方，这些标本后来成为维管植物名称的类型。确定采集者登顶的路线将有助于确定一些采集地点。古斯塔夫-曼恩（Gustav Mann）是第一个探索该地区的采集者；我们根据他的信件分析并绘制了他的行程图。此外，还分析了其他十支登顶探险队的行程。记录了成为维管植物物种名称类型的采集物。

During a survey of the macrofungal diversity in the Sweetgum Forest Nature Protection Area (Burdur Province), southwestern Turkey, we discovered a new species of Pluteus. The species is described and illustrated here as Pluteus canaliculatus, based on its morphological characteristics and molecular phylogenetic analyses. The new species was found on wood in a Liquidambar orientalis forest and is characterized by a light brown-yellow to reddish brown canaliculate pileus, ochre brown lamellar edges, a shiny, silvery cream stipe, predominantly ellipsoid basidiospores, mostly narrowly fusiform to fusiform pleurocystidia, often with a moniliform to flexuose neck, and an euhymeniderm or a transitional (hymeniderm and epithelium) type of pileipellis. Phylogenetic analyses of nuclear ribosomal internal transcribed spacer ITS1-5.8S-ITS2 (ITS) region sequences reveal that Pluteus canaliculatus belongs to Pluteus sect. Celluloderma, forming a distinct lineage in the /thomsonii clade. A description and a comparison with morphologically similar and closely related species are provided, together with colour photographs and line drawings of the species.

A new species of fern, Ceratopteris baguangensis was recently discovered in Shenzhen, Guangdong, China. Detailed morphological descriptions and photographs of the habitat are shown. C. baguangensis is similar to C. thalictroides and C. oblongiloba in the morphology of the fertile fronds but is distinct from them in the lobes of the sterile fronds. Furthermore, the chloroplast genome of C. baguangensis was sequenced and characterized. The annotated results revealed that the chloroplast genome had a conserved quadripartite structure, with a pair of inverted repeat regions (IRs) separating the large single copy (LSC) region and the small single copy (SSC) region, resulting in a total length of 149,755 base pairs (bp). The genome encodes a total of 120 unique genes, including 76 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Molecular evidence indicated that the C. baguangensis formed a distinct lineage and was sister to C. oblongiloba. Given the current population size of C. baguangensis in Baguang Heritiera littoralia Wetland Park, it is suggested C. baguangensis should be categorized as an Endangered (EN) species according to the criteria of IUCN. This study further enriches the diversity of the genus Ceratopteris and will help to elucidate their phylogenetic relationships.
最近在中国广东深圳发现了一种新的蕨类植物 Ceratopteris baguangensis。图中展示了详细的形态描述和栖息地照片。Baguangensis 在可育叶片的形态上与 C. thalictroides 和 C. oblongiloba 相似，但在不育叶片的裂片上与它们不同。此外，还对 C. baguangensis 的叶绿体基因组进行了测序和鉴定。注释结果显示，叶绿体基因组具有保守的四方结构，一对倒位重复区（IR）将大单拷贝区（LSC）和小单拷贝区（SSC）分隔开来，总长度为 149 755 碱基对（bp）。基因组共编码 120 个独特基因，包括 76 个蛋白质编码基因、36 个 tRNA 基因和 8 个 rRNA 基因。分子证据表明，C. baguangensis 形成了一个独特的品系，是 C. oblongiloba 的姊妹。鉴于巴光姬蛙目前在巴光湿地公园的种群数量，根据世界自然保护联盟（IUCN）的标准，建议将巴光姬蛙列为濒危物种（EN）。这项研究进一步丰富了蠰属的多样性，有助于阐明其系统发育关系。

We conducted a molecular phylogenetic study of Athyrium focusing on species from Java, Bali, and Sulawesi using five chloroplast markers. We sample from type localities to help resolve the application of names which have been applied inconsistently throughout the Malesian floristic area and tropical Asia. We show that A. nigripes is known with certainty only from Indonesia and perhaps Malaysia, corroborating earlier conclusions that the name A. nigripes does not apply to plants from mainland China, or India. Moreover, we show that A. nigripes is closely related to A. pulcherrimum, a narrow endemic from Mt. Pangrango, Java. We also find a large polytomy of species including A. erythropodum from both Java and Taiwan, A. auriculatum, A. brevipinnulatum, and A. mearnsianum, that helps to both clarify species concepts and raises new questions about the application of names. Finally, we show that although the presence of spines and setae do not coincide with a recent infrageneric classification of Athyrium, these characters remain useful for distinguishing large species groups.
我们利用五个叶绿体标记对鱼腥草（Athyrium）进行了分子系统发育研究，重点是爪哇、巴厘岛和苏拉威西岛的物种。我们从模式产地取样，以帮助解决在整个马利西亚花卉区和亚洲热带地区应用不一致的名称问题。nigripes 这一名称不适用于中国大陆或印度的植物。此外，我们还发现 A. nigripes 与 A. pulcherrimum 关系密切，后者是爪哇 Pangrango 山的狭长特有种。A. auriculatum、A. brevipinnulatum 和 A. mearnsianum，这既有助于澄清物种概念，也对名称的应用提出了新的问题。最后，我们表明，虽然刺和刚毛的存在与最近的鱼鳞目下属分类不一致，但这些特征对于区分大型物种组仍然有用。

Two new species of Cystodermella, C. canadensis and C. rubrogranulosa, are described based on phylogenetic and morphological grounds, and compared with similar species. Four holotypes were barcoded: Agaricus terryi, Cystoderma texense, Lepiota sipariana and Melanoleuca vinosa. Two new combinations are proposed: Melanoleuca vinosa as Ripartitella vinosa, and Cystodermella contusifolia as Cystolepiota contusifolia. Cystodermella cristallifera and C. sipariana are found to be conspecific; the older name, C. sipariana, should be adopted and C. cristallifera deprecated as a later synonym. The holotypes of three species: Agaricus terryi, Cystoderma texense and Cystodermella mazahuanensis all represent Cystodermella cinnabarina, for which a neotype is selected.

Brachystele guayanensis is hereby transferred to the genus Cyclopogon based on molecular systematics and morphological evidence. The major change in the circumscription of Cyclopogon with the inclusion of this species is an increase in the number of flowers per inflorescence, a reduction in flower size, and the fact that sepals may become petaloid.
