A new species of Pleroma from Serra dos Carajás, Pará state, Brazil, is described. Pleroma carajasense occurs in southeastern Amazonia, northern Brazil, in canga vegetation, on ironstone outcrops. It is morphologically related to Tibouchina caatingae, because both are shrubs with elliptic to oval leaves, conspicuous petioles (3–17 mm and 10–15 mm, respectively), a pair of elliptic bracteoles, and purple petals, anthers (both cycles) and style. Pleroma carajasense differs from T. caatingae by its chartaceous leaves (versus coriaceous in T. caatingae), with an obtuse to cuneate base (vs. obtuse to subcordate), hypanthium 4–7 × 1.2–4 mm (vs. 10–15 × 3–5 mm). According to IUCN criteria, this species should be considered endangered (EN). A morphological description, illustrations, photos in the field, scanning electronic micrographs of the leaf indumentum and seeds, information on conservation status and distribution are presented.

Pariana caxiuanensis (Poaceae) is described and illustrated as a new species from the Brazilian Amazon. The new species is characterized by having the leaves clustered at the apex of the leafy culm, fimbriae few to absent, dimorphic flowering culms, large ligules (2.5–4 mm long), and pubescent to hirsute synflorescences. We present a morphological description, illustrations of the new species, the conservation status assessment, and a key to differentiate P. caxiuanensis from its morphologically related congeners.

A New Species

ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic distribution and conservation status of the species.

Hysterionica s.l. (including Neja) comprises ca. 15 species distributed mainly in the grasslands of southern Brazil, Uruguay, central and northern Argentina and Southern Paraguay. Based on field surveys, study of nomenclatural types and other specimens, and review of literature, a new species is proposed here, Hysterionica chamomilloides, endemic of mountainous regions of northern Uruguay, and southwestern Rio Grande do Sul state, Brazil. This work provides a detailed morphological description of the new species, information on its geographic distribution, habitat, phenology, conservation status, and discusses the main differences between H. chamomilloides and the morphologically most similar species. Illustrations, images and a key to the South American species of Hysterionica are also supplied.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

Ruellia anamariae, a new species of Acanthaceae is herein described and illustrated from the municipalities of Parauapebas and São Geraldo do Araguaia, Pará State, Brazil. The new species is recognized by its habit, a shrub up to 5 meters high, by its terminal thyrsus inflorescence, by its greenish-yellow corolla with the expanded portion of the tube suburceolate, strongly revolute lobes and shortly exserted stamens. It is also morphologically similar to Ruellia exserta, but differs by its habit, a shrub (not liana), inflorescence, thyrsus with opposite dichasia (not secundiflorous thyrsus) and short exserted stamens (not long exserted), and to Ruellia beckii differing by its habit, a shrub (not liana) end calyx lobes oblong-lanceolate with acute apex (not oblanceolate to obovate with retuse to obtuse apex). We provide a detailed description, illustrations, comments, data on distribution and habitat and conservation status of the species.

A new species of Mimosa is described from the Atlantic Rainforest and ecotone with the Cerrado of southeastern Brazil, in the states of Minas Gerais, Rio de Janeiro and São Paulo: M. porrecta L. Jordão, M.P. Morim & Baumgratz (Leguminosae). Related to M. sensitiva, it shares morphological affinities with this species but differs in having porrect-stellate trichomes, a new type of trichome for the genus, on the stems, and the dendritic trichomes in the fruits. The conservation status was assessed, according to IUCN criteria, as Least Concern.

A New Species

A new species of Lophogyne from a Brazilian Amazon savanna is described and illustrated. It is morphologically similar to the former Jenmaniella species, due to the presence of stems that arise from prostrate roots attached to the substratum, a gynophore at anthesis, and three prominent non-suture ribs per valve in the fruit, currently merged in Lophogyne s.l.. Lophogyne wilsonii can be distinguished from all others species of  Lophogyne s.l. by the apical region of the roots unattached from the substratum. The conservation status is discussed and an identification key is presented.

Iucn Criteria

Epitypes are proposed for two species of Hechtia: H. subalata and H. jaliscana, both endemic to Western Mexico. The holotypes of both species consist of fruiting specimens. While the female flowers of both species are extremely similar, the staminate ones are noticeable different: we select staminate vouchers as epitypes to clearly circumscribe both taxa. As a result of the delimitation of the concept Hechtia subalata and its geographical distribution, we identify a new species from Durango, Mexico, previously misidentified as Hechtia subalata: Hechtia marthae. We provide images portraying plant parts of all species, as well as photographs in habitat. Finally, assessments of the conservation status of the three species sensu IUCN criteria are included.
