Cirsium wulongense (Asteraceae), a new species from Xiannü Shan in Wulong district, Chongqing, China, is described and illustrated. This new species is similar to C. sichuanense in its nodding capitula and white corolla, but differs by having leaves discolorous (vs. concolorous), abaxially grayish white and densely tomentose (vs. green, glabrous or sparsely pubescent with long multicellular hairs) and phyllaries subulate (vs. acute) at apex. It is also closely similar to C. fanjingshanense in the campanulate involucre and patent to reflexed phyllaries, but differs by its stems pubescent with densely long multicellular hairs (vs. subglabrous), leaves pinnatilobate to pinnatipartite (vs. undivided), discolorous (vs. concolorous), abaxially grayish white and densely tomentose (vs. green and glabrous), and corolla white (vs. purplish).

This study establishes two new species, Aspidistra tenuistyla and A. luteo-rubra (Asparagaceae, Convallarioideae). The first one, Aspidistra tenuistyla, is described here as a new species for science. It was discovered in the lowland limestone area of Ba Be National Park (Bac Kan Province). A detailed illustrated description of this species, along with data on its distribution, ecology, and phenology, is provided. According to the criteria of the IUCN Red List, the conservation status of A. tenuistyla is estimated as Near Threatened (NT). Additionally, the species rank is proposed for A. luteo-rubra, the plant regarded earlier as a variety (A. lutea var. luteo-rubra). It was found in the limestone area of Ngoc Son-Ngo Luong Nature Reserve (Hoa Binh Province). Both plants belong to the group of species with narrowly tubular flowers and are most closely related to A. lutea. A detailed, illustrated comparison of A. tenuistyla, A. lutea, and A. luteo-rubra is additionally presented. All these species are endemic to the limestone regions of northern Vietnam.
本研究确定了两个新种：Aspidistra tenuistyla 和 A. luteo-rubra （天门冬科，Convallarioideae）。第一个新种 Aspidistra tenuistyla 被描述为科学新物种。它是在巴贝国家公园（巴坎省）的低地石灰岩地区被发现的。本文提供了该物种的详细图解描述，以及关于其分布、生态和物候的数据。根据世界自然保护联盟（IUCN）红色名录的标准，A. tenuistyla 的保护状况估计为濒危（NT）。此外，还提出了 A. luteo-rubra 的物种等级，该植物早先被视为变种（A. lutea var.）它被发现于玉山-吴良自然保护区（和平省）的石灰岩地区。这两种植物都属于狭管状花类，与 A. lutea 的亲缘关系最为密切。此外，还对 A. tenuistyla、A. lutea 和 A. luteo-rubra 进行了详细的图解比较。所有这些物种都是越南北部石灰岩地区的特有种。

The genus Peniophora is known to be distributed from boreal to tropical regions worldwide. During surveys of plant diseases in southern Thailand in 2022 and 2023, two specimens of rotten snake fruits (Salacca zalacca) were collected. The new species, P. salaccae, is described based on collections with morphological and molecular data. This species is characterized by orange-gray to brownish-orange basidiomes, simple-septate generative hyphae, brown lamprocystidia, subclavate to subcylindrical gloeocystidia, and subtriangular basidiospores. It can be distinguished from P. trigonosperma by its larger basidiospores and shorter lamprocystidia. Molecular phylogenetic analyses of the internal transcribed spacers (ITS) and the large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA) confirmed the position of the new species within the genus Peniophora. The full description, color photographs, illustrations, and the phylogenetic tree showing the position of P. salaccae are provided. Additionally, pathogenicity tests showed that P. salaccae could infect snake fruits, which developed the same symptoms under artificial inoculation conditions as those observed in the field.
据了解，蛇果属植物分布于世界各地的寒带和热带地区。2022 年和 2023 年在泰国南部进行植物病害调查时，采集到两份腐烂蛇果（Salacca zalacca）标本。根据采集到的形态学和分子数据，描述了新物种 P. salaccae。该物种的特征为橙灰色至棕橙色基部体、单隔生菌丝、棕色灯囊虫、近棍棒形至近圆柱形球囊虫和近三角形基部孢子。它可以通过较大的基生孢子和较短的灯囊虫与 P. trigonosperma 区分开来。核糖体 DNA（rDNA）内部转录间隔（ITS）和大亚基（nrLSU）的分子系统学分析证实了该新种在 Peniophora 属中的位置。本文提供了完整的描述、彩色照片、插图以及显示 P. salaccae 位置的系统发生树。此外，致病性测试表明，P. salaccae 可感染蛇果，在人工接种条件下，蛇果会出现与实地观察相同的症状。

Peliosanthes thachii is described and illustrated as a new species endemic to southern Vietnam. This is the fifth species found for the Neolourya group as it has a slender tortuous style with the stigma positioned above the level of anthers and an inferior ovary. The new species is morphologically closest to P. curviandra but it is distinguishable from all the others of the group by having smaller dimension leaves and floral parts, spherical and hardly open perianth, short and strongly tortous style and purple ovules. The data on phenology, distribution, and provisional assessment of conservation status of the new taxon are provided.
Peliosanthes thachii 被描述为越南南部特有的一个新种，并配有插图。这是发现的 Neolourya 群的第五个物种，因为它的花柱纤细曲折，柱头位于花药上方，子房下位。新种在形态上与 P. curviandra 最为接近，但由于叶片和花部尺寸较小，花被球形且几乎不开放，花柱短且强烈扭曲，胚珠为紫色，因此可与该组的所有其他物种区分开来。本文提供了这一新分类群的物候学数据、分布情况以及对其保护状况的临时评估。

One new species of Ophiopogon, O. guangzhouensis, from Guangdong Province in southern China, is described and illustrated. The new species is similar to O. bockianus, but differs markedly by its pedicel (1.3–1.7 cm long) longer than the stalky part of the floral base, adjacent anthers and filaments all completely connate, and style exerted beyond the tepals. This paper not only details their taxonomic features and relationships among similar species, but also provides data on the habitat and phenology of the new species. Based on critical observations on herbarium specimens (including type material) of nine other similar species, we also demonstrate that O. pseudotonkinensis is conspecific with O. bockianus and O. albimarginatus is synonymous with O. stenophyllus. We therefore reduce O. pseudotonkinensis and O. albimarginatus to the synonymy of O. bockianus and O. stenophyllus respectively.
本报告描述了产自中国南部广东省的一个新种Ophiopogon，即O. guangzhouensis，并绘制了插图。bockianus 相似，但花梗（长 1.3-1.7 厘米）长于花基部的柄部，相邻的花药和花丝完全合生，花柱位于花被片之外。本文不仅详细介绍了其分类学特征和同类间的关系，还提供了新种的生境和物候数据。基于对标本馆中其他九个相似种标本（包括模式标本）的关键观察，我们还证明 O. pseudotonkinensis 与 O. bockianus 为同种，而 O. albimarginatus 与 O. stenophyllus 为同名。因此，我们将 O. pseudotonkinensis 和 O. albimarginatus 分别归入 O. bockianus 和 O. stenophyllus 的同义类。

A new species, Ovicillium sinense, which was isolated from an infected pupa, is introduced. Morphological comparisons with extant species and DNA-based phylogenies from analysis of a multigene dataset of combined ITS, LSU and TEF sequence data support the establishment of the new species. It differs from other species by its phialides that are attenuated from the middle to the apex, the conidia aggregated in large globose to subglobose heads, and having shorter phialides and smaller conidia.

A new species of orchid, Bulbophyllum bokodense, is herein described and illustrated from Benguet Province, Luzon Island, Philippines. It closely resembles Bulbophyllum rinkei endemic to New Guinea, but is distinct by having a broader leaf, a shorter inflorescence, an acute petal apex, glabrous auricles, a slightly canaliculate labellum, mid lobe and apex of labellum devoid of concavity, and a longer stelidia. A detailed description, photographs, and illustration are also provided. Preliminary conservation assessment of the new species following IUCN guidelines suggest a conservation status of data deficient (DD).

Abatia mantiqueirensis is described and illustrated as a new species with distribution for the Brazilian states of Minas Gerais and Rio de Janeiro. It is morphologically similar to A. americana but can be distinguished by the presence of canaliculated petiole, acute serrate leaf margin, glands at the apex of the margin serrations that are rounded to concave and projected outwards from the leaf blade, upper portion of the pedicel winged and seeds with tiny dorsal wings. Taxonomic description, comments, and geographical distribution information are here in provided. So far, only three populations of A. mantiqueirensis are known with only one of them recorded in a protected area. Based on the availability of suitable habitats, possible threats and future potential geographical distribution, we propose the conservation status for A. mantiqueirensis as Critically Endangered.
Abatia mantiqueirensis 是一个新物种，分布于巴西的米纳斯吉拉斯州和里约热内卢州。americana 相似，但其区别在于叶柄呈管状，叶缘有锐利的锯齿，叶缘锯齿的先端有腺体，腺体呈圆形至凹形，从叶片向外突出，花梗上部有翅，种子背侧有小翅。这里提供了分类学描述、评论和地理分布信息。到目前为止，已知的 A. mantiqueirensis 种群只有三个，其中只有一个记录在保护区内。基于合适栖息地的可用性、可能存在的威胁和未来可能的地理分布，我们建议将曼提克龙蜥的保护级别定为极危。
