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

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

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

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.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

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

The new species Biancaea scabrida, currently only known from Peninsular Malaysia, is described and illustrated. The new species most resembles B. parviflora and B. oppositifolia in its inflorescence, but can be distinguished from both species by its sepals which have short stiff scabrid hairs, and its pistil which has stiff and hispid hairs. It also has alternately arranged leaves and inflorescence branches, a lack of a persistent suborbicular stipule, few pinnae per rachis (2–6 pairs) and relatively fewer leaflets per pinna ((3–)5–9 pairs). A provisional IUCN conservation assessment and a taxonomic key to Biancaea is also provided here.

A New Species

Bauhinia includes about 150 species distributed across the tropics. Most Neotropical species belong to Bauhinia ser. Cansenia that includes unarmed trees and shrubs, mostly from areas under seasonally dry climate. A new species of this series is described here from the northeastern Brazilian states of Bahia and Sergipe. Bauhinia corifolia occurs in open vegetation on sandy soils of Restinga vegetation at the Atlantic coastal forests. It is morphologically similar to B. acuruana by sharing the entire and ovate leaflet with a retuse to emarginate apex and a cordate base, but differing by its tall shrub to treelet habit, larger leaves with a glabrous and glossy upper surface, shorter bracts, and longer flowers. We provide description, illustration and distribution map for the new species.
