Typhonium bicolor and T. culaochamense are described as new species endemic to Central Vietnam. They have bicolored staminodes (apex and base of different colors) which are formerly reported for six species, namely T. bachmaense, T. blumei, T. filiforme, T. flagelliforme, T. kbangense and T. ramosum. The first species is characterized by its oblong-elliptic and thick leaflets, yellowish and elliptic flattened anthers with lateral dehiscence, pink 6–7 mm long staminodes with a pale purple verrucose surface and a bright yellow and obtuse or truncate apex, oblanceolate ovaries and stipitate spadix appendix, and the second by its elongate and cylindrical tuber, variable leaf blades, longer spathe tube, basically externally green-brownish spathe limb, 3–5 rows of pistils, apically brownish dotted ovaries, disciform stigmas and recurved staminodes with a yellow apex. The ecology, distribution and assessment of conservation status of the two new taxa as well as a key to all known Typhonium species in Vietnam are provided. 
Typhonium bicolor 和 T. culaochamense 被描述为越南中部特有的新种。它们有双色退化雄蕊(先端和基部颜色不同),以前曾报道过六种,即 T. bachmaense、T. blumei、T. filiforme、T. flagelliforme、T. kbangense 和 T. ramosum。第一种的特征是:小叶长圆状椭圆形,厚;花药淡黄色,椭圆形,扁平,有侧开裂;退化雄蕊长 6-7 毫米,粉红色,表面浅紫色,先端钝或截形,呈亮黄色;子房倒披针形;穗状花序附录具柄;第二种的特征是:小叶长圆状椭圆形,厚;花药淡黄色,椭圆形,扁平,有侧开裂;退化雄蕊长 6-7 毫米,粉红色,表面浅紫色,呈亮黄色,先端钝或截形、第二种是长圆柱形块茎,叶片多变,佛焰苞筒较长,佛焰苞瓣片基本呈绿褐色,雌蕊 3-5 排,子房顶部有褐色小点,柱头盘状,退化雄蕊下弯,先端黄色。本文提供了这两个新分类群的生态学、分布和保护现状评估,以及越南所有已知 Typhonium 物种的检索表。

Amoenoboletus brachysporus is described as a new species from Southern China. Morphologically, it is closely related to A. granulopunctatus and A. mcrobbii, but distinguished by its relatively larger basidiomata with the pileus covered with conspicuous greyish yellow to yellowish brown patches or coarse fibrillose squamules, longer and broader stipes densely covered with dark red, appressed squamules, and obviously shorter basidiospores (7–9 × 5–6.3 μm). Phylogenetically, newly generated sequences from the new species form a distinct clade within the genus Amoenoboletus. Detailed morphological descriptions, colour photographs of the new species and comparisons with closely related taxa are presented. 
Amoenoboletus brachysporus 被描述为中国南方的一个新物种。mcrobbii 的亲缘关系密切,但区别在于它的基殖体相对较大,绒毛上覆盖有明显的灰黄色至黄棕色斑块或粗纤维鳞片,托叶较长、较宽,密布暗红色贴伏鳞片,基殖体明显较短(7-9 × 5-6.3 μm)。在系统发育上,新物种的新生成序列在 Amoenoboletus 属中形成了一个独特的支系。文中提供了新种的详细形态描述、彩色照片以及与近缘类群的比较。

During studies of Piperaceae in Northeastern Brazil, we found names lacking designated type material, among them Piper consanguineum. We revised the synonyms, protologues and bibliographies where names have been cited. A neotype has been designated for Piper consanguineum (Kunth) Steud., as well as a lectotype for Piper surinamense C. DC., which also had a syntype excluded from its name. 
在对巴西东北部胡椒科植物的研究中,我们发现了一些缺乏指定模式标本的名称,其中包括 Piper consanguineum。我们修订了同物异名、原植物志和引用名称的参考书目。Piper consanguineum (Kunth) Steud.已被指定为新模式标本,Piper surinamense C. DC.也被指定为讲座模式标本,其名称中也排除了一个合模式标本。

Neotypification of Cistanche tubulosa (Schenk) Wight ex Hook.f.: a name applied to a widely distributed, polyphyletic group of plants Cistanche tubulosa (Schenk) Wight ex Hook.f.的新分型:一个用于广泛分布的多型植物群的名称

The name Cistanche tubulosa s.l. is used from Africa and the Middle East to South and Central Asia and China, however this name is applied to plants that have been shown to comprise a polyphyletic group. Maintaining the use of this species name across distinct lineages is untenable, but inclusion of a type specimen in further analyses is needed to correctly apply names to revised taxa and to evaluate the recent decision to place the name in synonymy under the name C. tinctoria (Forssk.) Beck. Therefore, we proposed a neotype for Cistanche tubulosa (Schenk) Wight ex Hook.f. We contextualise the relevant taxonomy with a broader discussion on taxonomic challenges in the genus Cistanche in which several species are traded for herbal medicine, rare, or are of conservation concern.  
肉苁蓉(Cistanche tubulosa s.l.)这一名称从非洲和中东一直沿用到南亚、中亚和中国,但这一名称所适用的植物已被证明是一个多态群。在不同的世系中继续使用该种名是站不住脚的,但需要在进一步的分析中纳入模式标本,以便正确地将名称应用于修订的类群,并对最近将该名称置于 C. tinctoria (Forssk.) Beck 的同义中的决定进行评估。因此,我们为 Cistanche tubulosa (Schenk) Wight ex Hook.f 提出了一个新原型。我们通过对肉苁蓉属分类学挑战的更广泛讨论,对相关的分类学进行了背景介绍,其中有几个物种被作为草药交易、稀有或受到保护关注。

Field investigations and specimen examination revealed no obvious morphological differences among Brandisia chevalieri Bonati, B. discolor J.D.Hooker & Thomson, and B. scandens Bonati. This observation, coupled with previously established phylogenetic evidence, confirms B. chevalieri and B. scandens as synonyms of B. discolor. The issue concerning the type designation of B. discolor has been sorted out and clarified. A key to the species of Brandisia is also provided. 
实地调查和标本检查显示,Brandisia chevalieri Bonati、B. discolor J.D.Hooker & Thomson 和 B. scandens Bonati 之间没有明显的形态差异。这一观察结果,再加上之前确定的系统发育证据,证实了 B. chevalieri 和 B. scandens 是 B. discolor 的异名。有关 B. discolor 的模式标本的问题已经得到解决和澄清。此外还提供了布兰迪西亚种的检索表。

Pestalotiopsis phyllostachydis sp. nov. is introduced during a study of the diversity of bambusicolous fungi in Guangdong Province, China. The new species exhibits similar conidial morphology, pigmentation, and dimensions to its relatives; however, it can be distinguished by the length of its apical and basal appendages. The identification is corroborated by a phylogenetic analysis incorporating combined ITS, tef1-α and tub2 sequence data. A refined description and illustration of P. phyllostachydis are provided, accompanied by a morphological comparison of this new taxon and its closely related taxa compiled in a table. In addition, the common morphological characteristics utilized for interspecific identification are discussed incidentally.

Eremogone bingolense is described a new species from Bingöl province (Türkiye). The new species is related to E. cucubaloides and E. dianthoides, but it differs from E. cucubaloides by the glabrous stem, sheat and pedicel lengths, length of glabrous sepals, and petals shape and size (about 2 times longer than the sepals). E. bingolense differs from E. dianthoides by inflorescence shape and number of flowers, sheath, pedicel and sepal lengths. Ecological data and conservation status of the new species are also presented. A distribution map of the new taxon and related species is provided.

Caperonia (Acalyphoideae, Euphorbiaceae) is a monophyletic genus with 36 species naturally distributed in Latin America, Africa, and Madagascar. Its greatest diversity occurs in South America, where 28 species are found. Caperonia species are herbs or subshrubs that occur exclusively in open marshy environments. Here, we describe Caperonia itapevae, a new endangered species known from a single record from South Brazil, based on extensive morphological study and phylogenetic data.
Caperonia(Acalyphoideae,大戟科)是一个单系属,有 36 个物种,自然分布在拉丁美洲、非洲和马达加斯加。其最大的多样性出现在南美洲,有 28 个物种。Caperonia 属于草本或亚灌木,只生长在开阔的沼泽环境中。在此,我们基于广泛的形态学研究和系统发育数据,描述了 Caperonia itapevae,这是一种新的濒危物种,仅有来自南巴西的一个记录。
