A New Species

Vicia mingyueshanensis, a new species from the Mingyue Mountain Region of western Jiangxi, China, is described and illustrated. It is a perennial climbing liana that always links to riparian woods. A morphological comparison indicated that the new species is closely similar to Vicia taipaica K. T. Fu and Vicia dichroantha Diels; however, it differs from the other two species by several salient characters, such as plant indumentum, stipule shape, corolla colour, bractlet shape and calyx shape. Photographs, a preliminary conservation assessment, table of morphological characters and distribution map comparing this new species to two morphologically-similar species are also provided.

A New Species

Myrcia amplifolia, a new species from the coastal forest of southern Bahia, eastern Brazil, is here described and compared with morphologically similar species. Additionally, a morphological plate, distribution map and conservation assessment of the species are presented. We assign the new species to Myrcia sect. Calyptranthes with a reasonable reliability due to the combination: presence of cataphylls, inflorescences sympodially branching at the base and calyptrate flowers. Myrcia amplifolia seems to be closely related to M. carioca, from which it can be distinguished through the leaf blades strongly coriaceous (vs. chartaceous in M. carioca), leaf venation very slightly raised and barely conspicuous abaxially (vs. venation strongly raised and conspicuous abaxially), inflorescences with a shorter main axis (75–110 mm long vs. 130–270 mm long), and shorter first lateral branch (3.3–19 mm long vs. 48–95 mm long), and the calyptra acuminate (vs. rounded or shortly apiculate). It is also similar to M. boanova, differing by the leaf blades significantly larger (31–60 × 10–20 cm vs. 7–13 × 4.1–5 cm in M. boanova) and strongly coriaceous (vs. chartaceous), and the calyptra acuminate (vs. rounded) and smaller (2.3–2.6 × ca. 1.8 mm vs. 3.5–3.7 × 3.5–4 mm).

Onobrychis farimanensis is described as a new species and an identification key, illustrations and distribution map provided. The new species is restricted to the north Zharf Mountains between Fariman and Torbat-e Heydarieh, in the Khorasan Razavi Province of Iran. It is a perennial herb, becoming woody at the base and has long wing petals, standard as long as the keel, and pods loosely covered by appressed hairs. The new species differs from morphologically similar taxa, O. alamutensis and O. major, in several morphological characters such as plant height, stem indumentum, leaflet length and indumentum, bract length, calyx length, corolla colour, and pod size and shape.

Abstract—Monteiroa rubra is described as a remarkable new species from Rio Grande do Sul, Brazil. It is notably distinct from the other ten species of Monteiroa. The new species is morphologically most similar to the four species of the genus with unlobed leaves that also lack cordate leaf bases. Monteiroa rubra apparently is an endemic species known from three localities in wetlands associated with grasslands in Augusto Pestana and Fontoura Xavier municipalities in southern Brazil. A morphological description, distribution map, photographs, ecological notes, and a key to morphologically most similar species are presented. According to IUCN criteria, if a formal assessment were performed, the new species would probably be considered Endangered.

A New Species

We describe and illustrate here a new species of Rinorea from the Brazilian states of Bahia and Espírito Santo, under the name Rinorea gemmulata. The new species occurs in the understory of seasonally dry riparian and semi-deciduous forests. The new species could be diagnosed by the combination of opposite leaves, free stamens, velutinous connective and for the unique presence of perulate buds. We provide a distribution map, a preliminary IUCN conservation assessment, and illustrations, as well as morphological comparison with the sympatric R. ramiziana and the putatively related R. vaupesana and R. villosiflora.

A New Species

During the review progress of a manuscript describing a new species from Xizang (Tibet), we found that, close to acceptance of our manuscript, the same species had just been published as Begonia medogensis. For better understanding this species, we supplemented the description of this species with further illustrations, additional specimens, updated distribution map, further comparison with similar species and a conservation assessment (NT).

We describe and illustrate a new species of Mandevilla for the states of Oaxaca and Veracruz, Mexico. Mandevilla sherlockii sp. nov. can be separated from the other similar species of the genus by its subcoriaceous leaf blades and inflorescences with a conspicuously curved rachis between each flower. Including this new species, Mexico is a hotspot for the genus with a 24 species, 11 of which are endemic. We provide a distribution map, suggest a conservation status for the new species, and provide a key for the species of Mandevilla found in Mexico and Central America.

A New Species

Abstract―Randia heteromera is a new species described based on studies of taxonomy and vegetative anatomy (leaf, stipule, and colleters). This species is illustrated and diagnosed in comparison to the other four similar species of Randia in the Southern Cone of America. The species grows in areas of humid forests, locally known as the humid Chaco in the southern part of its distribution (Argentina and Paraguay), and in seasonal forests in the northern part, in northeast Paraguay and the south of Mato Grosso do Sul in Brazil. We present a key to distinguish R. heteromera from the other species of the Southern Cone of America. The species was also compared with similar taxa, Randia nitida or R. hebecarpa, occasionally used to identify material from the Southern Cone of America. A distribution map is provided. The anatomical data studied had a taxonomic value at the species level. In addition, based on the leaf anatomy studies carried out in the present study and in previous studies, three new types of vascular tissue organization in the leaf are described for Rubiaceae.

Stachytarpheta grandiflora, an endemic species to campos rupestres of the Parque Nacional da Serra da Canastra, west of Minas Gerais, Brazil, is described and illustrated. The new species is characterized by pubescent branches, leaves with acute apex, petiole 0.5–1 cm long, bracts 0.7–1 cm long, with caudate apex, calyx 1.5–1.6 cm long, pubescent, 2-toothed and corolla 2.3–3 cm long, dark blue. It belongs to the informal group “Sellowiana”. We provide a detailed diagnosis, a morphological comparison with the most similar species, a key for the informal group where the new species belongs, a distribution map, conservation status and illustrations.

A New Species

Background – Cyclodium is a neotropical fern genus comprising about ten species. Most species are found in northern South America, and the foothills of the Guiana Shield is an important region for species diversification. Our phylogenetic and taxonomic studies of the genus demonstrated the need to describe a new species and to recognize a variety at species level.Methods – This study is based on herbarium specimens from CAY, HUA, INPA, MBM, NY, P, RB, UC, UFP, UPCB, and US. Morphological characters were analyzed using standard procedures. The indumentum and spores of the new species were studied using a scanning electron microscope. Species delimitation is proposed based on our preliminary phylogenetic studies, as well as on morphology and geographical distribution.Key results – Cyclodium alansmithii Bohn & Labiak is recognized as a new species, described, and illustrated. The most similar species is Cyclodium inerme (Fée) A.R.Sm., from which it differs by ovate-lanceolate and bicolored scales, reduced fronds, truncate pinna bases, and non-ciliate indusia. Cyclodium alansmithii is currently assessed as Endangered (EN) using IUCN criteria, but more fieldwork and herbarium studies are necessary to establish a more accurate conservation assessment. Cyclodium trianae (Mett.) A.R.Sm. var. chocoense A.R.Sm. is here elevated to species rank. A key to species of Cyclodium with free veins is provided.
