Based on literature consultation and specimen survey, we demonstrate that the Himalayan species Delphinium scabriflorum (Ranunculaceae) has been largely misunderstood. We agree with the previous treatment of placing D. altissimum in synonymy with D. scabriflorum. We determine that those specimens from Bhutan previously referred to D. scabriflorum and those from Cona in China’s southern Xizang (Tibet) previously referred to D. conaense or D. umbrosum var. drepanocentrum represent a new species, which we describe as D. pseudoscabriflorum herein. This species, currently known only from Bhutan and the closely adjacent Cona county in southern Xizang, China, is similar to D. ludlowii, a species endemic to Bhutan, and D. scabriflorum, a widely distributed Himalayan species, but differs by an array of characters with respect to leaf division, pedicel indumentum, shape of bracteoles and their position on the pedicel, shape of sepaline spurs, and follicle pubescence.
根据文献查阅和标本调查,我们证明喜马拉雅物种Delphinium scabriflorum(毛茛科)在很大程度上被误解了。altissimum 与 D. scabriflorum 的同义关系。scabriflorum,以及中国西藏南部科纳的标本以前被称为 D. conaense 或 D. umbrosum var. drepanocentrum,我们将其描述为 D. pseudoscabriflorum。ludlowii和广泛分布于喜马拉雅山脉的D. scabriflorum相似,但在叶裂、花梗毛被、小苞片的形状及其在花梗上的位置、萼状距的形状以及蓇葖果的短柔毛等方面存在一系列特征差异。

In this study, four terrestrial collections of bactrodesmium-like hyphomycetous fungi were isolated from rotten wood in Guizhou Province, China. Phylogenetic analyses based on the combined LSU, ITS, mtSSU, and SSU sequence matrix indicate that these four isolates represent one species belonging to the Sclerococcum within the Dactylosporaceae, and present a distinct lineage. Therefore, Sclerococcum pseudobactrodesmium sp. nov. was introduced with corresponding morphological descriptions. Sclerococcum pseudobactrodesmium represents the first lignicolous asexual species from a terrestrial habitat. 
本研究从中国贵州省的朽木中分离出了四种陆生类菌丝真菌。基于 LSU、ITS、mtSSU 和 SSU 组合序列矩阵的系统发育分析表明,这四个分离物代表了 Dactylosporaceae 中属于 Sclerococcum 的一个物种,并呈现出一个独特的世系。因此,Sclerococcum pseudobactrodesmium sp.Sclerococcum pseudobactrodesmium 是来自陆生栖息地的第一个木质化无性物种。

Floras and taxonomic papers covering the region of the Eastern Carpathians frequently include a taxon of the Valeriana tripteris and V. montana affinity, under various names, most frequently as Valeriana transsilvanica or V. tripteris subsp. heterophylla. After having collected and cultivated a new material from Slovakia and Poland, we discovered that the taxon in question is a separate species, a tetraploid (2n=32) occupying a special habitat and a wide geographical range in Poland, Slovakia, Ukraine and Romania, distinct from both V. tripteris and V. montana. An analysis of relevant (seventeen) names and their original material, where applicable, found the name Valeriana dacica Porcius as the correct specific name for this taxon. Diagnostic characters, habitat requirements and an outline of its geographic distribution are provided. Notes on all relevant names, including the misapplied ones or invalid names surviving in important databases are given. Five names are newly typified.

Bulbophyllum xiajinchangense (Orchidaceae), a new species from Yunnan province, China, is described and illustrated. It is morphologically similar to B. scabratum, but differs by its free (vs. convergent) lateral sepals, the ratio of mean lateral/dorsal sepal length (ca. 2.0 vs. ca. 3.0), purplish-red (vs. pale yellow-ochre) flowers. Phylogenetic analysis based on nuclear ribosomal ITS and two plastid (matK and psbA-trnH) sequences support B. xiajinchangense as a distinct species, which forms an independent lineage sister to B. levinei, B. gedangense and its allies. 
本文记述了中国云南省一新种——夏金昌ense(兰科)。它在形态上与B. scabratum相似,但不同之处在于其自由(与收敛)的侧萼片,平均侧/背萼片长度的比例(约2.0 vs. 3.0),紫红色(vs.淡黄赭色)的花。基于核糖体ITS和两个质体(matK和psbA-trnH)序列的系统发育分析支持B.夏金changense是一个独立的物种,与B. levinei、B. gedangense及其亲缘关系形成一个独立的姊妹谱系。

An unknown Giffenia taxon was sampled from the tidal flat sediment of Suncheonman Bay in the Republic of Korea on June 11, 2018. To identify the species, a detailed analysis using light and electron microscopy and a literature review were conducted. The important morphological characteristics—thin lip-shaped sternum, elongated alveoli, and eccentric raphe slit—were found in the species. These features are not present in previously described Giffenia taxa (Giffenia cocconeiformis). The new diatom species is characterized by (1) a slightly undulated valve face, (2) a lip-shaped sternum with a slightly rough surface, (3) numerous elongated alveoli on the valve face, and (4) an eccentric raphe slit. We propose Giffenia koreana sp. nov. as a new epipelic diatom taxon. 
2018年6月11日,在韩国顺天湾的潮滩沉积物中采集了一个未知的吉芬尼亚分类群。通过光镜、电镜分析和文献综述,对该物种进行了鉴定。重要的形态学特征是薄唇形胸骨、细长的肺泡和偏心的中缝。这些特征在先前描述的gifenia分类群(gifenia cocconeiformis)中不存在。新硅藻种的特征是:(1)瓣面略起伏,(2)唇形胸骨表面略粗糙,(3)瓣面上有许多细长的肺泡,(4)偏心的中缝。本文提出韩国吉菲尼亚硅藻属(Giffenia koreana sp. 11 .)为新的藻门上硅藻分类群。

A new species of the genus Adlafia (Anomoeoneidaceae, Bacillariophyta) from Moscow Region (Russia) and North Macedonia 来自莫斯科地区(俄罗斯)和北马其顿的 Adlafia 属(Anomoeoneidaceae, Bacillariophyta)新物种

Adlafia is a relatively small diatom genus in terms of number of species and consisting of small-celled species with delicate morphology that is barely visible under the light microscope. Only a few morphological characteristics recognizable under a light microscope can be used to identify species. This could lead to a broader species concept and misidentifications of species. Recent observations of the diatom flora of Russia and North Macedonia reveal the existence of a new Adlafia species. This study describes it based on light and scanning electron microscopy observations. The new species resembles Adlafia minuscula, but its valves are narrowly lanceolate, more slender and have a smaller width. The species is probably widely distributed in Europe, but was overlooked in earlier studies. 
阿德拉菲亚硅藻是一种相对较小的硅藻属,种类数量较少,由小细胞种类组成,形态微妙,在光学显微镜下几乎看不见。只有一些在光学显微镜下可以识别的形态特征可以用来识别物种。这可能导致更广泛的物种概念和物种的错误识别。最近对俄罗斯和马其顿北部硅藻区系的观察揭示了一种新的硅藻物种的存在。本研究基于光学和扫描电子显微镜观察来描述它。新种类似于小叶蝉,但其瓣狭窄披针形,更纤细,宽度更小。该物种可能广泛分布在欧洲,但在早期的研究中被忽视了。

Examination of a sediment sequence from Huguangyan Maar Lake (HML) in southeast China revealed the presence of a new Aulacoseira species in samples dated to the Lateglacial. Using light microscopy (LM) and scanning electron microscopy (SEM), this small-sized species is described as Aulacoseira huguang sp. nov. Its morphology is compared with those of similar species, such as A. subborealis (Nygaard) Denys, Muylaert & Krammer, A. pusilla (F. Meister) Tuji & Houki, A. stevensiae Weide, A. subarctica (O. Müller.) Haworth, A. scalaris (Grunow in Van Heurck) Houk, Klee & Passauer, A. distans (Ehrenberg) Simonsen and A. alpigena (Grunow) Krammer. Aulacoseira huguang sp. nov. can be differentiated by the following combination of characters: valve face covered in round areolae evenly spaced, a smooth collum, small cell size, the presence of two rimoportulae located on the ringleist, positioned in opposite places on the perimeter of the valve and spines that are separated from the first row of areolae. 
对中国东南部湖光岩麻尔湖(HML)沉积物序列的研究表明,在冰川期样品中发现了一种新的冰藻属物种。利用光镜和扫描电镜技术,将该小型物种描述为Aulacoseira huguang sp. 11 .,并与A. subborealis (Nygaard) Denys, Muylaert & Krammer, A. pusilla (F.

Using light microscopy (LM) and scanning electron microscopy (SEM), this small-sized species is described as Aulacoseira huguang sp. nov. Its morphology is compared with those of similar species, such as A. subborealis (Nygaard) Denys, Muylaert & Krammer, A. pusilla (F. Meister) Tuji & Houki, A. stevensiae Weide, A. subarctica (O.

Aulacoseira huguang sp. nov. can be differentiated by the following combination of characters: valve face covered in round areolae evenly spaced, a smooth collum, small cell size, the presence of two rimoportulae located on the ringleist, positioned in opposite places on the perimeter of the valve and spines that are separated from the first row of areolae.\u0000 ","PeriodicalId":20114,"journal":{"name":"Phytotaxa","volume":"30 5","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138590158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
