Trolliusaustrosibiricus (Ranunculaceae), a new species from South Siberia.

ABSTRACT: Trolliusaustrosibiricus Erst & Luferov, sp. nov., a new species from Russian South Siberia is described and illustrated. This new species is endemic to Western and Central Siberia. Morphologically, it is close to the East Asian species T.chinensis and T.macropetalus. However, it differs from the aforementioned species due to the morphology of the rhizomes, aerial shoots, sepals and petals. This species is also distinguished from T.asiaticus, which is widespread in Russia (Western and Eastern Siberia), Mongolia, China, north-eastern Kazakhstan and in the northeast of the European part of Russia, in having a smaller number of sepals, longer persistent styles and petals longer than sepals. In addition, an identification key for all Russian species is given and all species have been discussed.

Ranunculusluanchuanensis (Ranunculaceae), a new species from Henan, China.

Project description:Ranunculusluanchuanensis (Ranunculaceae), a new species from Laojun Shan in Luanchuan county, Henan province, central China, is here illustrated and described. It is morphologically similar to R.limprichtii in having 3-lobed and subreniform basal leaves, 3-lobed cauline leaves, and small flowers with reflexed and caducous sepals, but differs by having slender and basally slightly thickened roots (vs. fusiform), prostrate stems (vs. erect), obliquely ovoid and glabrous carpels and achenes (vs. widely ovoid and puberulous), longer styles in the carpels (ca. 1.2 mm vs. 0.6-0.8 mm) and achenes (ca. 1.8 mm vs. 0.6-0.8 mm), and glabrous receptacles (vs. sparsely puberulous). Ranunculusluanchuanensis, currently known only from its type locality, is geographically isolated from R.limprichtii, a species widely distributed in Gansu, Qinghai, Sichuan, Xizang (Tibet) and Yunnan, China. The distribution map of this new species and its putative closest ally, R.limprichtii, is also provided.

Anemonastrum tenuicaule and A. antucense (Ranunculaceae), new combinations for a New Zealand endemic species and its South American relative.

Project description:A rational taxonomic circumscription of genera in tribe Anemoneae (Ranunculaceae) is briefly discussed. It is concluded that, in view of the morphological diversity of the group and recent molecular phylogenetic findings, a moderately narrow approach to the re-circumscription of genera earlier included in Anemone sensu lato is preferable, in particular, with the recognition of the lineage with the base chromosome number x = 7 (Anemone subgen. Anemonidium) as two genera, Hepatica sensu stricto and Anemonastrum in an expanded circumscription (including Anemonidium, Arsenjevia, Jurtsevia, and Tamuria). Following these conclusions, new nomenclatural combinations are proposed for two related species endemic to New Zealand and South America, respectively: Anemonastrum tenuicaule (= Anemone tenuicaulis, Ranunculus tenuicaulis) and Anemonastrum antucense (= Anemone antucensis). Information on typification is updated: the lectotype of Anemone antucensis is the specimen from P and not a specimen from G, and the lectotype of Ranunculus tenuicaulis is a specimen from AK. Biogeographic scenarios already proposed to explain the relationship of these two species and some other South America - New Zealand distribution patterns are discussed. It is concluded that the long-distance dispersal scenario fits best the available data for Anemonastrum. Two host-specific and geographically restricted species of Urosystis parasitizing A. tenuicaule and A. antucense are briefly discussed.

Coptishuanjiangensis, a new species of Ranunculaceae from Guangxi, China.

Project description:Coptishuanjiangensis, a new species of Ranunculaceae distributed in the valleys of Jiuwanshan National Natural Reserve in Huanjiang county (Guangxi, China), is described and illustrated for the first time based on morphological and plastome sequences data. It differs from C.chinensis, C.deltoidei and C.omeiensis mainly by having notably longer petiole, scape, bigger leaf blade with lobes obviously remote and robust rhizomes without stolons. Phylogenetic analyses support that C.huanjiangensis is sister to C.omeiensis and C.deltoidei.

Clematismae (Ranunculaceae), a new species of C.sect.Meclatis from Xinjiang, China.

Project description:Clematismae Z.Z.Yang & L.Xie, a new species of Ranunculaceae from Xinjiang, China, is described and illustrated. The new species is morphologically similar to C.orientalis and C.glauca but can be distinguished for being a less hairy plant (hairy in C.orientalis), often 2-ternate leaves (1-2-pinnate for C.orientalis and C.glauca), lanceolate to linear-lanceolate leaflets (elliptic or ovate in C.glauca), larger flowers (smaller flower in C.orientalis) and narrowly lanceolate sepals with acute to slightly attenuate apex (narrowly oblong sepals in C.orientalis and ovate to broadly lanceolate sepals in C.glauca). The new species is endemic to the southern slope of North Tianshan Mountain in Central Xinjiang. The conservation status of the species is also discussed.

Complete chloroplast genome of Clematis taeguensis (Ranunculaceae), an endemic species from South Korea.

Project description:The complete chloroplast (cp) genome sequence of Clematis taeguensis Y.N.Lee (Ranunculaceae) was determined to be 159,534 bp in length, consisting of large (79,326 bp) and small (18,338 bp) single-copy regions and a pair of identical inverted repeats (30,935 bp). The genome contains 92 protein-coding genes, 32 tRNA genes, 8 rRNA genes, and 1 pseudogene (infA). Phylogenetic analysis of 19 taxa inferred from the chloroplast genome showed a relationship with C. taeguensis, which is also recognized as a species endemic to the Korean Peninsula. The complete cp genome sequence of C. taeguensis reported here provides important information for future phylogenetic and evolutionary studies in Ranunculaceae.

A new species of Stamnaria (Leotiomycetes, Helotiales) from Western Siberia.

Project description:A new species of Stamnaria is described based on morphology and molecular data from a collection made in West Siberia. Stamnaria yugrana is differentiated by lanceolate, strongly protruding paraphyses and comparatively narrow, fusoid-clavate ascospores. The apothecia are urn-shaped due to a prominent and even collar as in S. persoonii. The species grows on fallen side branches of Equisetum sylvaticum, a rarely recorded host for Stamnaria. The authors formally describe the new species and provide colour illustrations. In addition, the literature is reviewed on previously described species of Stamnaria. Phylogenetic reconstruction of the Stamnaria lineage, based on the ITS ribosomal DNA, strongly supports the three currently recognised species: S. americana, S. persoonii and S. yugrana.

A new species of Ranunculus (Ranunculaceae) from Western Pamir-Alay, Uzbekistan.

Project description:New data on the phylogeny of four rare and endemic species of RanunculusL.sect.Ranunculastrum DC. of western Pamir-Alai, one of which is new to science, have been obtained. Ranunculustojibaevii sp. nov., from the Baysuntau Mountains, Western Hissar Range of Uzbekistan, is described. The new species is closely related to R.botschantzevii Ovcz., R.convexiusculus Kovalevsk. and R.alpigenus Kom., but differs in the blade of the radical leaves, which is rounded-reniform, segments 3-5-dissected, each 2-5-partite with elongated, rounded apical lobes. A phylogenetic analysis, using both the nuclear ribosomal internal transcribed spacer (ITS) and cpDNA (matK, rbcL, trnL-trnF), was informative in placing R.tojibaevii in context with its most closely-related species. Discussion on the geographic distribution, updated identification key, a detailed description, insights about its habitat and illustrations are provided.
