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).

A New Species

A new species of Tradescantia sect. Austrotradescantia endemic to rocky cliffs in Southern Brazil, is here described as Tradescantia seubertiana. This new species is characterized as being completely glabrous, with a leaf base obtuse to cordate to slightly amplexicaulous, ellipsoid flower buds, by its light-pink to pink petals, and for growing in wet rocky cliffs. The new species is morphologically most similar to T. crassula due to its erect habit, conduplicate to canaliculate, succulent leaves, with inconspicuous secondary veins, non-saccate cincinni bracts, pistil longer than the stamens and hilum longer than ½ the length of the seed. I present a description, an illustration, a distribution map, habitat description, and a conservation assessment for the new species. I also present a comparison and identification key for the species related to T. seubertiana.

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.

Baccharis magnifica, a new species endemic to the summits of the Serra do Caparaó along the border between Espírito Santo and Minas Gerais, southeastern Brazil, is described. The new species is easily recognized by its shrubby habit, showy green and slightly wine-tinged, long-petiolate leaves with ciliate margins and corymbiform capitulescences. It is morphologically most similar to the allopatric B. macrophylla, which inhabits the mountain summits of the southerly Serra da Mantiqueira range. Illustrations, a distribution map, habitat information, and a conservation assessment are also provided for the 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.

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).

Taraxacum sandomiriense Wolanin, a new species of Taraxacum sect. Erythrosperma from Poland is described. It is a triploid (2n=24) characterized by strongly corniculated inner bracts, brown-colored achenes and distinctly haired leaves. It is an extremely rare taxon found in the xerothermic plant communities in the Świętokrzyskie Province. The species conservation assessment for T. sandomiriense determines its threat status as Critically Endangered, since it consists of three populations with a very small number of individuals. A detailed species description, photographs, distribution map, notes on ecology and chorology are provided.
