A New Species

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.

Schinus pampeana is a new species from Brazilian Pampa. The new species was tentatively included in Schinus sect. Terebinthifolia, and is morphologically most similar to Schinus lentiscifolia and S. weinmanniifolia. We present here a detailed morphological description, a geographical distribution map, IUCN conservation status assessment, ecological data, photographs, and a table of diagnostic characters of S. pampeana and the most similar species. Schinus pampeana increases the total number of Schinus to about 49 species, of which eleven are recorded in Brazil.

A New Species

We describe and illustrate Paepalanthus capixaba, a new species of Paepalanthus ser. Paepalanthus. The species is endemic to Espírito Santo state and restricted to a very distinct and endangered area, which comprises a mosaic of quartzitic sandy patches within a granitic argillaceous site. The indument of leaves, spathes, and scapes is crucial to recognize the taxon as a unique entity. The species is compared to Paepalanthus klotzschianus, the morphologically most similar species. An official conservation status of critically endangered species was assessed by the Centro Nacional de Conservação da Flora committee. Comments on the occurrence area and the morphological variation of the species, as well as a distribution map, photos, and illustrations are provided.

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

A new species from the state of Goiás, Brazil, Phyllanthus pterocaulis, is described and illustrated, with comments on its geographic distribution and environmental preferences, phenology, morphological relationships, and systematic position. It is morphologically allied with Phyllanthus avicularis, P. heliotropus, and P. hyssopifolioides, but differs from all of them by a set of characters related to cymules sex, presence and types of trichomes on leaves and stems, leaf consistency, numbers of sepals in flower of both sexes, integrity of stamens, capsules and seeds. Additionally, we provide images of the new species in the field, conservation status, mapped distribution, the anatomical description of its stem and leaves, and a key to differentiate it from the other similar species belonging to Phyllanthus sect. Loxopodium occurring in Brazil. The new species is one of the few in the genus that occurs in shaded environments in seasonal dry forests within the Cerrado biome.

Aristolochia luudamcui (Aristolochia subgen. Siphisia, Aristolochiaceae), a new species from Vietnam, previously misidentified as A. utriformis, is described and illustrated here. The new species is most similar to A. pseudoutriformis and A. utriformis concerning the morphology of the leaf lamina, the color of the perianth, and the shape of the limb, but A. luudamcui can be distinguished from the other two species by having a deeply 3-lobed limb and a glabrous, yellow inner surface of limb lobes. A detailed description, information on ecology, phenology, distribution, usage, a provisional assessment of the conservation status of the new species, and a comparison with morphologically similar species are provided as well.

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.

Baccharis rectialata (Compositae: Astereae), a new species of B. sect. Caulopterae from the grasslands in northeastern Uruguay is described. The new species is morphologically similar to B. crispa and can be differentiated by its straight wing margins, shorter involucres and pappus in staminate capitula. We provide a detailed morphological description, and information on the distribution, habitat, phenology, and conservation status. Additionally, we discuss the main differences between B. rectialata and other closely related and morphologically similar species, and provide a key for identification of subshrubs belonging to B. sect. Caulopterae occurring in Uruguay, as well as illustrations, images, and a distribution map of the new species.

A new species of Lippia endemic to the Brazilian Atlantic Forest is described and illustrated. Lippia diversifolia is currently known from the inselbergs of Espírito Santo and Rio de Janeiro and is characterized by markedly tetragonal branches, of which the opposed sides are densely strigose and the other glabrescent, with indument alternating in the subsequent internode, leaf blade cartaceous to coriaceous, adaxial surface strigose, abaxial surface tomentose or strigose, peduncle 3.5–9 cm long, bracts strigose with apex acute, inconspicuous calyx, and white sessile glands along the whole plant. We provide field photographs, distribution map, conservation status and a table with the main characters that distinguish it from Lippia rubella, which is a morphologically similar species.

A New Species

Scoparia is a genus comprising ten species distributed mainly in the grasslands of southern Brazil, Uruguay, Argentina and Paraguay. Based on field surveys, study of nomenclatural types and other specimens, and review of literature we found an interesting new species of Scoparia from southern region of the State of Rio Grande do Sul, Brazil, and Department of Cerro Largo, northeast Uruguay. Described here as S. pentapetala. This work provides a detailed morphological description of the new species, information on geographic distribution, habitat, phenology, conservation status and, discusses the main differences between S. pentapetala and the morphologically most similar species. Illustrations, images and a distribution map are also supplied.
