A New Species

Six species of the genus Rhabdosciadium (Apiaceae) were studied by molecular phylogenetic analysis. The taxonomic status of each of them has been confirmed, the genus Rhabdosciadium turns out as a well-supported monophyletic group closely related to the genera Aegopodium, Caropodium, Carum, Falcaria, Fuernrohria, Gongylosciadium, Grammosciadium s.s., Hladnikia, Olymposciadium, etc. Rhabdosciadium anatolyi sp. nov. is described and illustrated as a new species from Hakkâri province, eastern Turkey. It differs from the other taxa of the genus, in addition to its unique geographical range, in the large terminal leaf lobes with regularly serrated margin, mainly ternate primary basal segments of leaves, and long internodes.

A New Species

Abstract Background Hyoscyamus, the largest genus in the tribe Hyoscyameae, harbors more than 20 species. Although the monophyly of Hyoscyamus is supported by both morphological and molecular phylogenetic studies, the delimitation of Hyoscyamus has been hotly debated in different classifications. Here, we report a new species of Hyoscyamus (Solanaceae) from Henan Province, China, and discuss the delimitation of Hyoscyamus. Results This species is morphologically similar to the known species of Hyoscyamus and its close related genus Archihyoscyamus, but can be distinguished by corolla 2-lipped, adaxial lip 3-lobed and much longer than abaxial lips, tube slender at base, and stamens 5, inserted on inner side of disk, free, obviously unequal, and exceeding corolla. Phylogenetic analysis based on four chloroplast markers including rbcL, ndhF, trnC-psbM and trnL-trnF, strongly suggested that the new species was sister to a monophyletic group containing all species of Hyoscyamus and Archihyoscyamus previously described. Conclusions Both the morphological observations and molecular phylogenetic analyses support the recognition of Hyoscyamus labiatus as a new species. Our study also showed that Archihyoscyamus should be a synonym of Hyoscyamus. The delimitation of Hyoscyamus is thus revised in our study.

Tetrataenium mianguaqi, a traditionally used medicinal herb in Cangyuan County, SW Yunnan, China, is described as a species new to science and illustrated. Molecular phylogenetic analysis based on nuclear ITS well supports its belonging to Tetrataenium sensu stricto. The new species can be easily distinguished by its unique peltate, palmatilobate basal and lower leaves from the other five Chinese Tetrataenium species.

A New Species

A new species of Gesneriaceae, Oreocharis jasminina S.J.Ling, F.Wen & M.X. Ren from Hainan Island, south China, is highlighted and described. The new species is distinguished by its actinomorphic corolla, narrow floral tube and ovate anthers hidden in the floral tube. The new species also showed clear geographic and altitudinal isolation from the three currently-recognised Oreocharis species on the Island. Molecular phylogenetic analysis, based on nuclear ITS1/2 and plastid trnL-trnF sequences, supported the delimitation of the new species, which forms a single lineage with all the other Oreocharis species from Hainan Island. The roles of geographic and floral isolation in the evolution of the new species and its affinities are discussed.

Fungal Genus

A strain of the fungal genus Mariannaea, isolated from decayed leaves of Japanese red pine (Pinus densiflora), was identified to be a new species based on its molecular phylogeny and morphology. Molecular phylogenetic analysis revealed that the fungus belongs to a clade containing M. punicea and related species (M. punicea-related species) and that it forms a lineage independent of these species. Microscopic morphological comparisons with M. punicea-related species indicated that the new isolate differs with respect to the width of the phialides and length of the conidiophores. Comparison of macroscopic morphological characteristics revealed that M. punicea-related species are characterized by reddish-purple colonies, whereas the new isolate lacks this distinctive pigmentation. Moreover, the surface structure of the colonies of this fungus has a distinct irregular undulate pattern toward the margins. Given that this isolate can be clearly distinguished from the known M. punicea-related species, we consider the fungus to be a newly identified species, for which we propose the name Mariannaea imbricata sp. nov.

A New Species

Pilaira australis, a new species of fungus in the coprophilous genus Pilaira, was isolated from emu (Dromaius novaehollandiae) faeces and is described. Morphologically, the species resembles other species in the genus, particularly P. moreaui, except differs in its unique combination of sporangiophore height and sporangiospore length. Molecular phylogenetic analysis indicates that P. australis is distinct from other species in the genus with two regions, the internal transcribed spacers (ITS) and a fragment of the pyrG gene, showing 91% and 90% identity to the nearest species, respectively. Ultrastructure features and carbon utilisation were determined for P. australis, and may provide characteristics for species identification in this genus.

A New Species

Codonopsis atriplicifolia (Campanulaceae) from western Sichuan, China, is described here as a new species, which is similar to C. subscaposa in a number of characters. The results of molecular phylogenetic analysis of 25 species of Codonopsis based on chloroplast DNA fragments (matK, petD with petB-petD, rbcL) show that C. atriplicifolia is closely related to C. farreri. In morphology, the new species is distinctly different from the allied species by its linear-lanceolate leaves with subentire to pinnatipartite margins.

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.

A New Species

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.
