We describe and illustrate the new species Paepalanthus thomasianus (P. subg. Platycaulon, Eriocaulaceae) from São Paulo, Brazil, and compare it with other morphologically similar species. P. thomasianus is characterized mainly by its leaf indumentum, composed by long multicellular trichomes. Undulations formed by the vascular bundles in the leaf surface and the wide ratio between the leaf base and the middle region of the leaf are also useful to recognize the species. The morphological variation, habitat, geographic distribution, and conservation status of this new species are discussed.

We here describe and illustrate Begonia tadungensis (B. sect. Platycentrum), a new species from southern Vietnam. The new species is most similar to B. albopunctata in having broadly ovate leaves, three free styles, 4-loculed ovary, and berry-like fruits with a beaked apex, but differs mainly in having a glabrous abaxial leaf surface (not densely red pubescent), and fruits with gray puberlous hairs (not white papillose). It is also similar to B. pendens in its broadly ovate leaves and monoecious breeding system, but differs in having 6 tepals in the pistillate flowers (not 5) and 4-loculed ovaries (not 3-loculed). Information on ecology, conservation status, and a further comparison of characters with these two similar species is also provided.

A New Species

We present a new species, a new synonym, the resurrection of a species that has been synonymized before, updates on the distribution of three species, and lectotypifications for two species of Meriania from the Brazilian Atlantic Forest. Meriania baumgratziana is a new species apparently restricted to montane areas in the western portion of the state of Rio de Janeiro. It can be recognized by the sessile to subsessile leaves, these lanceolate, elliptic lanceolate or oblong-lanceolate, with cordate to cordulate, amplexicaul bases (seldom narrowly round), the abaxial surface in young leaves with the union of the primary and the inner pair of secondary veins with a membrane forming pocket domatia, these with trichomes emerging from the inside, then in older leaves the membranes frequently enlarged, globular, these hypertrophied structures sometimes caducous, or easily removed by friction, and by the pendulous inflorescences with 4-merous flowers. Meriania paratyensis Chiavegatto & Baumgratz is synonymized under M. sanchezii R.Goldenb., which in turn is resurrected from what we understand as a mistaken synonymy under M. paniculata DC. We present a discussion and illustrations of leaves and fruits, in order to explain these changes and compare all these three species, plus a fourth similar species, M. glabra (DC.) Naudin. The distributions of Meriania calyptrata (Naudin) Triana and M. sanchezii are updated, the former with the inclusion of specimens collected in the western tip of the state of Rio de Janeiro (it was previously recorded only for eastern São Paulo), and the latter in the exactly opposite way, with new records from Rio de Janeiro added to the previously known specimens from São Paulo. Finally, lectotypes are designated for Meriania calyptrata and M. glabra (DC.) Naudin (this superseding a previous, unnecessary designation of a neotype).

A new species, Neea itanhaensis, is described from São Paulo State, Brazil. N. itanhaensis differs from the other Neea species by its inflorescences with verticillate branching and sessile or subsessile leaves with an acute or oblique base and prominent secondary veins on the abaxial surface that diverge at less than a 90º angle from each other.

A new species of the genus Holoaden is described from the Atlantic forest of the state of São Paulo, Brazil, being restricted to primary or slightly disturbed high altitude cloud forests along the northeastern portion of the Serra do Mar. The typelocality is determined as Estação Ecológica de Bananal, in the Municipality of Bananal, State of São Paulo, Brazil. The new species is characterized by its moderate body size (female 42.6–44.2 mm SVL; male 37.2–38.5 mm SVL) with long and slender limbs, a head wider than long, a highly glandular dorsum, covered by well developed macroglands that extend to the internasal region, thigh and tibia, and an intense dark brown dorsal coloration and dark grey ventral surface.

Background and Aims: Aristolochia is the largest genus in Aristolochiaceae and is widely distributed in the world. A recent synopsis of Aristolochia in Costa Rica recognized 19 species; nevertheless, recent botanical exploration in southwestern Costa Rica has revealed yet another new species of this genus. Methods: The new species resulted from fieldwork in Buenos Aires, Puntarenas Province. Specimens from several herbaria were examined, as well as the type material of the most morphologically similar species. Comments about its distribution, habitat, phenology, conservation status and morphological distinction from related species are provided.Key results: Aristolochia quiricoana, a member of Aristolochia series Thyrsicae, is described and illustrated from the southern Pacific region of Costa Rica, where it is apparently endemic. It is similar to A. ornithorhyncha, from which it is distinguished by its shorter pedicels, wider, oblong perigone limbs with a shorter appendix, and a different floral color pattern.Conclusions: The new taxon described here represents the 22nd species documented in Aristolochia series Thyrsicae, as well as the 20th species of the genus from Costa Rica.

A New Species

Background and aims – The genus Anemopaegma (Bignoniaceae) includes around 47 species and has its centre of diversity in Brazil. Here, we describe and illustrate a new species from French Guiana, Anemopaegma kawense, and compare it to the two most similar species, A. foetidum and A. granvillei. We further assess the conservation status of all three species.Material and methods – Morphological descriptions are based on herbarium specimens deposited at BM, BR, CAY, INPA, K, MO, P, SPF, and U, and, in the case of the newly described species, also on field observations. The conservation status assessments follow the IUCN Red List criteria.Key results – Anemopaegma kawense differs from both A. foetidum and A. granvillei by its densely villose twigs, longitudinally plicate leaflets with secondary veins not or hardly prominent below, and tertiary veins impressed below. It is further separated from A. foetidum by the leaflets that are villose below and the calyx that is entirely pubescent outside. On the other hand, A. kawense differs from A. granvillei by the densely lepidote outer surface of the corolla, shorter petiolules, leaflets with midrib impressed above, shorter bracts and bracteoles, inflorescence peduncle exceeding the rachis, and pedicels densely puberulous, not lepidote or only sparsely so at the apex. This species is endemic to the Kaw Mountain in north-eastern French Guiana, where it grows in low stunted forest on laterite; it is assessed as Endangered according to the IUCN criteria. New descriptions are provided for A. granvillei, which is newly reported from Suriname, and for A. foetidum, which is newly reported from French Guiana; these two species are assessed as Endangered and Least Concern, respectively. Lectotypes are designated for A. maguirei, which is here synonymised with A. foetidum, and for A. umbellatum, another synonym of that species. A key to the 12 species of Anemopaegma occurring in the Guianas is presented.
