A new species, Polygala guilanica (Polygalaceae), is described from Kooh-Roubar, Gasht-Roodkhan protected area in W Guilan province, N Iran. The new species is distinguished based on its prostrate stem; small, lanceolate, ovate and rhombic, sessile leaves; tiny pink-white flowers in lax terminal racemes; 6 or 8 stamens with sessile anthers, a filiform style and brownish seed with 3-lobed caruncle. Detailed morphological description of the new species, photographs and distribution map are provided. Polygala guilanica is compared with the morphologically closest species: P. kurdica, P. hohenackeriana and P. anatolica. An updated identification key is provided for the Iranian species.

An attractive and interesting new species, Muscari savranii Uysal & Doğu (Asparagaceae) is described and illustrated from central Anatolia, Turkey. A complete morphological description, detailed photographs, and a distribution map are reported for the new species, including an identification key for related species. Muscari savranii grows on the inclined limestone slopes in the province of Kayseri, Turkey. The closest species appears to be Muscari tenuiflorum Tausch, a member of the subgenus Leopoldia (Parl.) Rouy. In this study, diagnostic micro-macro morphological characters are discussed and compared with related taxa. Moreover, M. savranii is characterized in terms of its chromosomal features and a comparison with its relatives is given.

Abstract—We present a new species, Turnera fasciculifolia, from the Jalapão region, the largest continuous protected area of Cerrado in Tocantins State, in central Brazil. The new species belongs to Turnera series Leiocarpae, and it can be recognized by the linear ericoid leaves with revolute margin, generally without extrafloral nectaries, and the basal leaves of the young axillary branches gathered in fascicles. We provide a description, illustrations, a distribution map, and a comparison with T. genistoides and T. revoluta, which also have ericoid leaves.

A new species of Persicaria, P. humboldtiana, endemic to a narrow area of waterfalls in Corupá, southern Brazil, is described in the present paper. The locus classicus of the new species is well-known for plant endemisms. A complete morphological description, original pictures, a distribution map, and a morphological comparison with the similar Eurasian species P. minor (≡ Polygonum minus) are given. The name Polygonum minus is lecto- and epitypified on, respectively, a Morison’s illustration and a specimen preserved at BM.

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.

Recent botanical explorations in Sierra Madre Occidental in Durango, Mexico, led to the discovery of a new species which according to its morphology belongs to Salvia sect. Brandegeia. The new taxon is morphologically most similar to S. oresbia from central Mexico, against which it is thoroughly compared. Additionally, it is presented a synopsis of the section in order to provide updated and standardized descriptions for those species known only in base to their protologues, which allows a more detailed and precise comparison in respect to the new species. The morphological examination of the species in the section also revealed that the recognition of S. sharpii as a distinct species from S. blepharophylla is not justified; consequently, it is reduced to synonymy. An identification key, a distribution map, photographs, and a drawing of the new species are also 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 freshwater Amphipod, Gammarus topkarai sp. nov., collected from Ivriz Creek, Tarsus Province, South Anatolia, is described and illustrated. The new species belongs to Gammarus pulex-group and shows similar characteristic features with Gammarus agrarius G. S. Karaman, 1973. Absence of well developed dorsal elevations on the urosome segments, smaller body length and relatively lower endopod/exopod ratio of third uropod are the most obvious features differ from G. agrarius. A detailed morphological description and illustrations of new species are given and differences from related species are discussed. An updated identification key of Gammarus taxa reported from Turkey, up to date, was also presented.

The detailed study of several Cohniella specimens observed and/or collected in French Guiana shows that they all belong to a single entity and that it is different from the two species previously cited for this country, Cohniella cebolleta and C. ultrajectina, by a set of significant vegetative and floral characters. This entity is here described as a new species, illustrated and compared with the two taxa mentioned. A distribution map of the hitherto known specimens and/or populations is proposed, as well as an identification key.

The species of Centris of the hyptidis group are revised. The group, composed by C. hyptidis Ducke, C. hyptidoides Roig-Alsina, and C. thelyopsis n. sp., exhibits unique morphological characters within the genus, like foreand midtrochanters with a laminar expansion at the base, and elaiospathes strongly modified. An updated catalog, and floral and distributional records are provided for each species, as well as an identification key and a distribution map. The male of C. hyptidoides is described for the first time and a modern diagnosis for C. hyptidis is presented. A new species, C. thelyopsis n. sp., is described from Goiás State, in central Brazil. It can be easily distinguished from the two previously known species by its predominant orange pilosity, including that of the hind legs and metasoma.
