Two new species of Cryptanthus from Bahia State, in northeastern Brazil, are described and illustrated. Cryptanthus apiculatantherus occurs in Atlantic Forest and Cryptanthus brevibracteatus was discovered in a transition area between Atlantic Forest and Caatinga. Cryptanthus apiculatantherus and C. bibarrensis have similar stem lengths and leaf blade shapes, but differ mainly by the stem diameter, width of the leaf sheaths, sepal and petal color, anther apex shape, and length and width of the ovary. Cryptanthus brevibracteatus and C. warren-loosei have a similar leaf blade color and are geographically close to each other, but differ by the number of flowers in the apical cluster of flowers of the inflorescence, length and width of the floral bracts, length of the sepals, connation of the sepals and length of the sepal lobes. Data about the geographic distribution, habitat, phenology, conservation status, taxonomic comments, a distribution map and photographs of the new species are provided. In addition, there are tables included that compare the new species to morphologically similar species.

Adenocalymma, with approximately 75 species, is one of the largest genera from tribe Bignonieae (Bignoniaceae). The genus mostly includes yellow-flowered lianas and shrubs that are conspicuous components of the dry and wet Neotropical forests. As part of an ongoing taxonomic and phylogenetic study of this group, we found unusual materials that do not match any of the currently recognized taxa. These materials formed the basis of two new species described here, which are endemic from the Brazilian Atlantic forest: Adenocalymma lineare, and Adenocalymma apetiolatum. Adenocalymma lineare resembles Adenocalymma nervosum on the linear leaflets, but differs in the habit, prophyll morphology, leaflet venation, floral bracts, bracteole morphology and dimensions, corolla color and morphology, anther and stigma position. While Adenocalymma apetiolatum closely resembles Adenocalymma sessile and Adenocalymma subsessilifolium on the sessile leaf insertion and shrubby habit, it differs from both species by the corolla color, indument type and color. Apart from that, Adenocalymma apetiolatum differs from the former by the prophyll morphology, floral bract and bracteole morphology, and the latter by the corolla morphology. These two new taxa are illustrated, and distribution maps are provided here. Notes on the taxonomy, geographic distribution, habitat, and conservation status are also included.

Abstract—Two new species of Turnera (Passifloraceae s. l., Turneroideae), T. acangatinga and T. ibateguara, from the Atlantic Forest of northeastern Brazil, are described. Some specimens of T. acangatinga were originally treated as T. annularis. Turnera ibateguara was recently considered part of T. pernambucensis, a species which also occurs in the Atlantic Forest in northeastern Brazil, and which was, until then, only known from the type material. In this study, recent collections of T. pernambucensis in the state of Alagoas revealed that both are distinct species and that have been mistakenly identified so far. We provide data on morphology, distribution, habitat, and phenophases, a preliminary conservation status assessment for the three species, and a key to the species with capitate inflorescences from Alagoas and Pernambuco.

Blade Shape

Two new species of the genus Anthurium are described from the Serra do Brigadeiro State Park, in the Atlantic Forest region, southeastern Brazil. Anthurium atrovinosum was found from 1450 to 1720 m and A. brigadeiroense from 1260 to 1650 m. Although they are sympatric species, A. atrovinosum reaches higher elevations, while A. brigadeiroense can be found up to 1650 m. Both belong to Anthurium sect. Urospadix subsect. Insculptinervia, but are easily differentiated by the leaf blade shape, fruit color. Descriptions, illustrations, photographs, comments on geographical distribution, ecology, phenology and comparisons with other similar species are presented.

A 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.

High Diversity

Brazil includes a very high diversity of bamboos, but this diversity is far from completely known. We increase the list of Brazilian woody bamboos by describing two new species of Chusquea, which belong to subgenus Rettbergia. Chusquea ciliatifolia sp. nov. differs from other species of this subgenus by its mottled culms, distinctly ciliate margins of the foliage leaf blades and pilose synflorescences; and C. mirabilis sp. nov. by the presence of branches with sericeous girdles. Both C. ciliatifolia and C. mirabilis occur exclusively in the Atlantic Forest, from the states of Bahia and Minas Gerais, known only from five and three populations, respectively. Comments on morphology, taxonomic relationships, ecological aspects, and conservation status of these new species are provided.

A New Species

Abstract—Araeococcus lageniformis is a new species described and illustrated here based on collections from the Atlantic Forest from the south of Bahia State, northeastern Brazil, and on morphological and anatomical characters. It is distinguished from A. nigropurpureus by the diameter of the tank, the morphology of the leaf, floral bracts, and sepals, by its sessile to nearly sessile flowers, its seed morphology, and by the presence of trichomes on both sides of the leaves. So far, the species is only known from Apuarema and Ibirapitanga municipalities. The type population was found in an unprotected area, fragmented by tracks and roads, where illegal logging takes place. Here we preliminarily assessed its conservation status as critically endangered.
