Abstract Muellera fragiliflora, a new species from the states of Bolívar and Cojedes, in Venezuela, is here described and illustrated. Information on its distribution, conservation status, flowering and fruiting as well as their morphological relationships with its closest relatives, M. sanctaemarthae and M. tubicalyx, is provided. This new species is distinguished by its flowers, bracts, and bracteoles without glandular pellucid dots, flowers with pedicel 5-6 mm long, bracteoles opposite and situated on the upper third part of the pedicel, as well as in having fragile flowers and turgid fruits. A dichotomous key is provided to the recognition of the Venezuelan species of Muellera.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).

A synopsis of the genus Cnidoscolus is presented for the midwestern region of Brazil, which resulted from the analysis of about 1,200 specimens from 62 national and foreign herbaria, including type collections. Observations of populations in field were also made. Nine species are recognized, one of which, C. mcvaughii, is new to science. It is described and illustrated, and comments about its geographic distribution, morphological relationships, systematic position, phenology, and conservation status are provided, as well as images and a map. The other species are contrasted by a dichotomous key. Also, distributional information, maps, conservation evaluations, images and morphologically diagnoses are included. Eight synonymizations, one lectotypification, a neotypifcation, and the re-establishment of C. neglectus are proposed.

A new species, Calea arachnoidea, which belongs to Calea sect. Meyeria, is hereby described and illustrated. This species occurs in the Serra Negra region, located in the southern portion of the “Zona da Mata” in the state of Minas Gerais, southeastern Brazil. Calea arachnoidea resembles C. quadrifolia, C. heteropappa and C. semirii, and its relationships with these species are discussed and an identification key for the species of C. sect. Meyeria in the state of Minas Gerais is provided. Additionally, photographs, a distribution map, comments about habitat and conservation status are provided.

A new species of Lophogyne from a Brazilian Amazon savanna is described and illustrated. It is morphologically similar to the former Jenmaniella species, due to the presence of stems that arise from prostrate roots attached to the substratum, a gynophore at anthesis, and three prominent non-suture ribs per valve in the fruit, currently merged in Lophogyne s.l.. Lophogyne wilsonii can be distinguished from all others species of  Lophogyne s.l. by the apical region of the roots unattached from the substratum. The conservation status is discussed and an identification key is presented.

The Chimanimani Mountains, located at the Mozambique-Zimbabwe border, are geologically unique in that they consist of quartzites giving rise to peaks and outcrops between zones of schist supporting grasslands. The nutrient-poor quartzitic soils house a high number of endemic plant species. One of these is Sericanthe chimanimaniensis, which is here described as new for science. We give a detailed description and distribution map, illustrations, information on ecology and phenology, and an assessment on the conservation status. An identification key to closely allied species is presented.

Schoenus is a predominately austral genus of sedges in which the Southern African taxa have recently received detailed taxonomic attention, starting with a transfer of 24 species into Schoenus from Tetraria and Epischoenus in 2017. The taxonomy of the Southern African Schoenus species is currently being revised, which has brought insight into the existence of several species new to science. Here, we build on this recent taxonomic work by describing one new species that has been previously overlooked (Schoenus inconspicuus), while including a distribution map, an assessment of conservation status and an updated identification key.

A new species of the genus Dictyanthus is herein described and illustrated, more than 30 years since the last paper describing new species of this genus. Dictyanthus stevensii sp. nov. is known only from the Zoque forest in the Chimalapas region in the state of Oaxaca, Mexico. This species differs from all other species because it has the smallest flowers within the genus. It is morphologically related to D. eximius, a microendemic species of Chiapas. Information on the distribution and habitat of this new species is given, and its conservation status is proposed as Critically Endangered B2ab(ii). An identification key to Dictyanthus species in southern and southerneast Mexico is also provided.

We describe and illustrate Wahlenbergia itatiaiensis, a new species of Campanulaceae, endemic to the Itatiaia National Park in the Atlantic Forest (Brazil). The new species is compared with W. linarioides, the sympatric and morphologically most similar species, and to W. intermedia. Wahlenbergia itatiaiensis is mainly distinguished by the linear to lanceolate leaves with few, short denticles along the margin, 3-locular ovary, and 3-lobed stigma. An identification key for these species is provided. The new species occurs on sandy and rocky, wet soils, adjacent to dirt roadsides of the upper part of the National Park. Detailed comments on the distribution and conservation status, as well as details of morphological variation and photographs are provided.

Licneremaeus braziliensis sp.nov. is described and illustrated based on female specimens collected from palm leaflets (Arecaceae) in Ilhéus, state of Bahia, northeastern Brazil. This is the first species of the genus described from this country. A dichotomous key for identification of all known species of Licneremaeus is proposed.
