查看更多>>摘要：A new species Camchaya bolavenensis (Asteraceae: Vernonieae: Centrapalinae) from Dong Hua Sao National Protected Area located in Bolaven Plateau, southern Laos, is described and illustrated. It resembles C. gracilis and C. thailandica in morphology but distinguished by its basally decumbent stem, margin of lamina with distinct (1-)2-3 teeth, 2-4 mm long on each side, invisible secondary veins, and a capitulum with 10-30 of florets.
查看更多>>摘要：A taxonomic revision of Taraxacum sect. Erythrocarpa in the eastern part of Europe and in the Alps is presented. Seventeen species are recognized, nine of them are described as new. Most species occupy relatively restricted geographical ranges, the most characteristic habitats being limestone cliffs and mountain summit areas. The highest species diversity of this section is situated in the mountain ranges of Greece and the adjacent regions of Bulgaria and North Macedonia; only two species are known from the Alps, and a new species is described also from Crimea, Ukraine. Taraxacum pindicola is the only sexual diploid among the taxa studied, the other taxa exhibit agamospermy. The name T. pindicola is newly lectotypified. The northernmost representative of T. sect. Erythrocarpa, T. pieninicum (S. Poland), is conspecific with T. erythrocarpum of the western Slovakia. The names T. albomarginatum A.J. Richards and T. voricola A.J. Richards are later synonyms of T. olympophilum Sonck. Taraxacum sect. Erythrocarpa is characterized and, for each species, nomenclature, typification, a detailed description or a reference to it, diagnostic notes, distribution and habitat, and a list of herbarium specimens studied are given. Most species are illustrated, and for selected ones, distribution maps are provided.

This species is distributed in slopes of stony rocky areas facing south of Lake Van (B5 Van Province). Muscari vanensis an endemic confined to East Anatolia, is related to mainly with M. botryoides and M. armeniacum. Diagnostic morphological characters have been discussed and compared with those of closely related taxa. At the first glance, the new species is easily separated from its relatives in its dwarf appearance and patent leaves, shorter scape, densely globose-oblong raceme, globose urceolate and swollen fertile flowers. Additionally, karyological, molecular and palynological data were used to support this diagnostic characters and to strengthen the taxonomic background of the new species.
查看更多>>摘要：The genus Trichoglossum belongs to the family Geoglossaceae (Geoglossomycetes) and they are traditionally known as earth tongues. The genus is characterized by black or dark brown club-shaped apothecia, inoperculate asci, with prominent hymenial setae, septate paraphyses, and long septate ascospores. Currently, this genus includes more than 20 species all over the world. The present novel species (Trichoglossum benghalense) was recorded from the lower Gangetic plain of India, which indicates its cosmopolitan distribution range. A detailed morphological description supported by a DNA sequence phylogram based on Maximum likelihood (ML) and Bayesian posterior probabilities (BPP) analysis, photo-illustrations, and line drawings are provided for this interesting species. A comparison with allied accepted species is also summarized.
查看更多>>摘要：Four new species of Herpothallon: H. capilliferum, H. polyisidiatum, H. subglobosum and H. viridi-isidiatum are described from southern China. Detailed taxonomic descriptions, ecological and chemical characters, and illustrations are provided for the new species. A key to all known Chinese Herpothallon species is also provided.
查看更多>>摘要：The typification of the name Hordeum marinum Hudson (Poaceae) is discussed. The name is lectotypified using an original illustration from Morison's Plantarum historiae universalis Oxoniensis, and an epitype is also selected. The type of the name H. gussoneanum is also discussed, and a specimen preserved at FI is designated as second step lectotype.
查看更多>>摘要：Tripogon sugathakumariae, a new species from Nelliyampathy hills of southern Western Ghats, Kerala, India, is described and illustrated. It is closely similar to T.bromoides but differs by distinct eciliate membraneous ligule fringed with long hairs at the ends of leaf sheath, shorter length of leaf blade, broad and straw-coloured spikelets, unidentate awned upper glume, lemma 3-lobed and 3-awned without a definite lobe between the median and lateral awns and median awn equal or slightly longer than lemma. Detailed description, distribution and ecology are provided along with a photo plate and illustration.
查看更多>>摘要：Cousinia sect. Stenocephalae is a mainly Iranian section of the genus and the second largest section of Cousinia after C. sect. Cynaroidae. Its members are mainly distributed in Iran. Using nrDNA ITS sequences, together with morphological evidence where possible, we tested the monophyly of C. sect. Stenocephalae as well as the related C. sect. Albidae and C. sect. Cousinia. We reconstructed phylogenetic relationships within these sections by performing a Bayesian analysis on a sample of 153 species of Cousinia, of which 49 species belong to the study sections. The analysis revealed that C. sect. Stenocephalae, Albidae and Cousinia are not monophyletic, which lays stress upon the need of a deep reexamination of the sectional classification in Cousinia using a different approach.
查看更多>>摘要：A new species, Leucoagaricus cupresseoides, from a pine forest in Castelfusano, Rome, Italy, is described based on both morphological and molecular analyses. Updated morphological descriptions of Leucoagaricus aurantiovergens and L. pseudopilatianus are presented due to new collections from Italy and confirmed by nrITS sequence analysis of the type specimens of the two species. Based on our morphological and molecular analyses, L. pseudopilatianus var. roseodiffractus and L. paracupresseus are synonyms of L. aurantiovergens; and L. pseudopilatianus var. rugosoreticulatus is not molecularly distinct from L. pseudopilatianus. Leucoagaricus cupresseus, L. cupresseoides, L. aurantiovergens and L. pseudopilatianus form the L. cupresseus complex for which a comparative table is provided.
