查看更多>>摘要：Hieracium boratynskii is a new, apomictic species described from the Karkonosze Mountains (Giant Mountains) in the Sudetes, SW Poland. It belongs to the H. canescens aggregate comprising taxa of presumably hybrid origin between H. schmidtii s. lat. and H. levicaule s. lat. The new species is illustrated with photos of the holotype and living plants; it is named in honour of Prof. Dr. Adam Boratynski.
查看更多>>摘要：The high Andean forests harbor great and unique biodiversity. Here, we report a new species of Epidendrum from Peru. Epidendrum alejandrinae is described, illustrated and compared with the morphologically similar Epidendrum ochoae, Epidendrum pachydiscum and Epidendrum aida-alvareziae. We performed a systematic review of herbarium information on the species reported for the Region of Huancavelica and compared the morphological features of the closest species to rule out possible matches. The new species is characterized by a short, foliate aggregate stems, an apical pendulous inflorescence formed from the stem, green resupinate flowers opening in succession, the petals and sepals semi-extended, a 3-lobed lip, lateral lobes obliquely ovoid, median lobe broadly cuneate, bicallose, and four, obovoid, laterally compressed pollinia. The novelty represents an important record for the flora associated with the high Andean forest dominated by Polylepis and Gynoxys in central Peru.
查看更多>>摘要：The genus Glossadelphus has been replaced by Phyllodon. However, Glossadelphus and Phyllodon are still used simultaneously in moss checklist of China. Total of 19 taxa of China published as members of the genus Glossadelphus are examined in this study. Our analyses show that only one species of Phyllodon (P. lingulatus) is recognized in China; twelve taxa of Glossadelphus in China are transferred to other genera (Bryocrumia, Ectropothecium, Entodon, Taxiphyllum); five taxa are excluded from the flora of China, and one species remains uncertain. Among them, two new combinations are proposed, Ectropothecium anomalum comb. nov. and E. falcatulum comb. nov. Myurella brevicosta is newly reduced to a synonym of Bryocrumia vivicolor. Glossadelphus isopterygioides is verified as a synonym of Entodon obtusatus. We newly designate lectotypes for G. anomalus and G. falcatulus. A list of 19 taxa of Glossadelphus of China is provided with their present status.

The new species grows in hygrophilous Atlantic Forest in Sao Paulo. Description, comparisons with morphologically similar species, etymology, taxonomic comments, illustrations, a map and the conservation status of the new species are provided.
查看更多>>摘要：We present a revision of the genus Parahyparrhenia for India including detailed description of the two endemic species i.e. P. bellariensis and P. khannae, with photo plates. Epitypification of P. bellariensis is done to facilitate correct identification. The present circumscription of the genus is also discussed with respect to irregular morphological characters of certain taxa, and its description is updated. Moreover, keys are provided to identify allied genera and all seven species of Parahyparrhenia that are currently globally accepted. Furthermore, each species is discussed in terms of its unique features and the relative taxonomic significance of these features in delimiting species. The genus has been globally reviewed. The African and Thai species have been discussed with a primary emphasis on their unique features and their utility in taxonomy.
查看更多>>摘要：Examination of plants from type locality and herbarium specimens revealed that the diagnostic characteristics are consistent among plants of Myristica beddomei subsp. beddomei and Myristica beddomei subsp. ustulata. Therefore, we propose synonymisation of M. beddomei subsp. ustulata with M. beddomei. However, M. beddomei subsp. spherocarpa was distinct from nominate subspecies in many morphological, anatomical and chemical attributes, and we therefore propose its elevation to species status with a new name, M. pushpangadaniana.

It is close to three other species: Cattleya bradei, C. briegeri, and C. cruziana. However, the new species differs in the number of nodes present in the pseudobulb components, the size of the diameter, the scent of the flowers and the time of flowering. In addition, its flowers have two unique chromatic characteristics that distinguish it from all other species with yellow flowers in the Parviflorae series: the color of the carinae and the whitish area at the base of the petals and sepals. We provide a detailed morphological description, a distribution map, in situ photographs, and compare it with similar species. We assessed its state of conservation as data deficient (DD), as the only know population consists of at least 150 mature individuals and is outside of an environmentally protected area.
查看更多>>摘要：Prunus yunkaishanensis, a new species of Prunus subg. Laurocerasus (Rosaceae), is described and illustrated. The new species is similar to P. phaeosticta and P. fordiana in their leaves with punctate abaxial surface, but it can be distinguished from the latter two species by having larger leaves with more pairs of lateral veins, shorter inflorescences with stout rachises, bracts persistent during anthesis, and ovoid fruits.
查看更多>>摘要：Dendrobium fuscifaucium is described here as a new species from Laos PDR. This species was found at a local nursery and was claimed to have been collected from the limestone mountains of Kasi District (Vientiane Province). Detailed description and comparison, comparison with its allied species, D. hekouense, D. luoi and D. wangliangii is provided, along with flowering phenology and information on habitat. Multiple attempts have failed to locate this species in the wild.
