Botanical explorations in the alpine zone of the Shahvar and Shah Kouh Mountains from Semnan and Golestan Provinces (northeastern Iran) led to the collection of interesting specimens of the genus Silene L. (Caryophyllaceae). Taxonomic study of these plants and comparison with determined plant specimens showed that the specimens belong to an unknown species. I describe it as S. aminiradii Gholipour, belonging to section Auriculatae (Boiss.) Schischk. from northeastern Iran. The new species is compared with S. lucida Chowdhuri and S. crispans Litv. as the most similar species. Silene aminiradii is a caespitose perennial alpine gynodioecious plant with prostrate stems covered with dense, retrorsely simple hairs. The distribution, ecological features, reproductive phenology, and photos of S. aminiradii are presented.

Unclear boundaries between species hinder identification in the field and in herbaria, especially in species groups that can only be distinguished on the basis of subtle morphological and ecological features. One such taxon is Ficinia indica, widespread in the Greater Cape Floristic Region, growing on deep sandy soils between sea level and 1000 m elevation. Within its range, several phylogenetically related and morphologically similar species co-occur or occupy distinct habitats. Studies in herbaria show species in the Ficinia indica complex to be largely misidentified based on the use of qualitative information. Here, we investigate whether the six taxa recognized, based on one or a few characters, are supported as distinct species based on multivariate analysis of macro-morphological data. Two of the taxa were mostly separated whereas the other four taxa overlapped in multivariate space, but all the taxa could be distinguished using a single or a combination of morphological and ecological characters. We uphold the four previously recognized taxa (Ficinia argyropus, F. elatior, F. indica, F. laevis) as species, describe two new species (F. arnoldii and F. montana), and provide a dichotomous key for their identification.

This is the first detailed taxonomic study of the genus Navicula in the Krasnodar Territory of the Caucasus region, Russia. During the study of the genus in waterbodies of the Adegoy River valley 15 taxa were recorded. Two species, N. adegoyensis sp. nov. and N. pseudocryptofallax sp. nov., are described as new to science. Their morphology is studied by light and scanning electron microscopy, and comparisons with morphologically similar species are provided. The use of the name N. avenacea for N. lanceolata sensu auct. is discussed. Navicula diversity was higher in the Adegoy River than in pools elsewhere in the river valley.

A new species, Macrobiotus derkai sp. nov., is described from a moss sample collected in the alpine zone of Sierra Nevada del Cocuy Mts (NE Colombia). It differs from the most similar species, Macrobiotus huziori Michalczyk & Kaczmarek, 2006 mainly in the location of the second macroplacoid and in the dimensions of accessory points on the claws. Eggs of the new species have the same type of areolation as eggs of M. huziori but they differ from the latter in the size and number of processes. The differences between the new species and others having similar number and shape of placoids are discussed. An identification key for these species is also provided. A round depression on the dorsal head cuticle is reported in Tardigrada for the first time. The results of a morphometric analysis of the new species are also given.

Gastrodia Brown (1810: 330) (Orchidaceae, Epidendroideae, Gastrodieae) is composed of approximately 90 species with a broad Old World distribution (Pridgeon et al. 2005, Chen et al. 2009, Cribb et al. 2010, Huang et al. 2015, Hsu et al. 2016, Jin et al. 2017, Aung et al. 2018, Suetsugu 2017, Suetsugu et al. 2018). During a survey of native plants in Fujian Province, an unknown species of Gastrodia was collected in August 2018 from the evergreen broad-leaved forest in Wuyishan National Park. A detailed examination of the specimens with similar species morphologically, G. fontinalis Lin (1987: 129), G. major Averyanov (2006: 21), G. punctata Averyanov (2006: 21) and G. huapingensis Huang, Hu & Liu (2015: 290), and two other species recorded from Fujian, G. elata Blume (1856: 174) and G. wuyishanensis Li & Liu (2007: 354), we confirmed it as a new species.

Allocheilos W.T.Wang in Gesneriaceae was described in 1983 and is characterized by its 4-lobed adaxial lip and undivided abaxial lip with acute apex. The genus is endemic to the karst regions in southwestern China and is classified as endangered due to habitat loss. During surveys of the karst areas in Yunnan of southwestern China in 2017, we collected two unknown species of the genus and later confirmed their novelty to science based on the detailed observation of their morphological characteristics, viz. A. maguanensis W.H.Chen & Y.M.Shui and A. rubroglandulosus W.H.Chen & Y.M.Shui. Their relationships with the similar species and provisional conservation status are discussed.

While assisting El Nido-Taytay Managed Resource Protected Area in their biodiversity monitoring of El Nido, Palawan, the authors came across a very distinctive and small population of Begonia. Based on careful investigation, the unknown species is confirmed as new to science, and is the latest addition to the species rich section Baryandra. A new species, Begonia cabanillasii is hereby described and illustrated. It is compared with phenetically similar species B. suborbiculata. Based on guidelines by IUCN, the new species is proposed to be Critically Endangered (CR) C2a.

Anthurium idimae is described from Espírito Santo and Rio de Janeiro states, in Southeastern Brazil. During the floristic survey of Araceae family in the Atlantic Forest, we found an unknown species with an intriguing combination of intermediate characteristics among A. cleistanthum, A. truncatum, A. molle, and A. cachoeirense. We described and illustrated the new species, including a comparative analysis of characters that distinguishes it from similar species, and also provide comments about its ecology, distribution and conservation.

Abstract—We describe and illustrate Paepalanthus fabianeae, a new species of Eriocaulaceae from the central portion of the Espinhaço Range in Minas Gerais, Brazil. Previous phylogenetic evidence based on analyses of nuclear (ITS and ETS) and plastid (trnL-trnF and psba-trnH) sequences revealed P. fabianeae as belonging to a strongly supported and morphologically coherent clade containing five other species, all of them microendemic, restricted to the Espinhaço range. Due to the infrageneric classification of Paepalanthus being highly artificial, we preferred not assigning P. fabianeae to any infrageneric group. Paepalanthus fabianeae is known from two populations growing in campos rupestres (highland rocky fields) in the meridional Espinhaço Range. The species is characterized by pseudodichotomously branched stems, small, linear, recurved, and reflexed leaves, urceolate capitula, and bifid stigmas. Illustrations, photos, the phylogenetic position, and a detailed description, as well as comments on habitat, morphology, and affinities with similar species are provided. The restricted area of occurrence allied with threats to the quality of the habitat, mainly due to quartzite mining, justifies the preliminary classification of the new species in the Critically Endangered (CR) category using the guidelines and criteria of the IUCN Red List.
