Pleurothallis minutilabia, a species unique in subsection Macrophyllae-Fasciculatae because of the minute, highly reduced lip, is described and compared to the most similar species in the subsection. It is also compared morphologically to Pleurothallis kaynagata from section Abortivae, to which P. minutilabia is not related, but which also possesses a highly reduced lip. The morphology of the flower of P. minutilabia is discussed briefly in relation to possible pollination mechanisms. The distribution, restricted to Zamora Chinchipe, southern Ecuador, and the conservation status are addressed.

A new species of Epidendrum from Peru, Epidendrum curimarcense, is described, illustrated and compared with the similar species Epidendrum ampelospathum. The new finding represents an important record for the flora associated with Polylepis forests of central Peru. The species has stems produced from a middle internode of the previous cane-like stem, a spathe, an elongate peduncle with several similar spaced bracts, flowers opening in succession, petals narrower than the sepals, a 3-lobed lip which is bicallose with rounded sub-equal lobes, and 4 obovoid, laterally compressed pollinia.

Trisetella pachycaudata, a new species in the subtribe Pleurothallidinae, was discovered in the Zamora Chinchipe province of southeast Ecuador, and it is described here. Trisetella pachycaudata is compared with the most similar species (and others with which it has been confused in cultivation), T. triglochin, T. strumosa, and T. vittata. It differs from them in the flowers with a much thicker apex of the sepaline tails (the thickest in the genus), and the petals expanded at the labellar margin, with the cuspidate apices erose on the upper margin and entire at the lower margin.

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.

A New Species

Astragalus dinawarii Bidarlord & F. Ghahrem. (Fabaceae) is described as a new species based on material collected on the Talesh Mountains, northwestern Iran. This species belongs to a large bifurcating section, Astragalus L. sect. Incani DC. Morphologically, it is close to A. bukanensis Maassoumi & Podlech, A. diversus Podlech & Maassoumi, and A. dilutuloides Maassoumi, F. Ghahrem. & Bagheri, sharing several densely hairy leaflets and stipitate legumes. This species is easily distinguished from similar species by a set of both vegetative and reproductive characters such as size, shape, number of leaflets, shorter calyx, and longer legume stipe. A detailed description and comparisons with similar taxa, color images, distribution and habitat, and conservation status of the new species are provided.

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.

A New Species

We describe a new species of glassfrog from the cloud forest of Manu National Park, southern Peru, at elevations of 2750–2800m. The new species is similar in morphology to Centrolene lemniscatum, which occurs in northern Peru at elevations of2000–2280 m. Both species have white labial stripes, humeral spines, and lack vomerine teeth. The new species differs from C.lemniscatum by its larger size, labial stripe extending into a distinct lateral stripe instead of a discontinuous lateral stripe, snoutprofile inclined anteroventrally instead of bluntly rounded, greater depression in the internarial area, and by having stronglyprotruding nostrils. Males of the new species emit long calls with 8–14 peaked notes, instead of a short tonal note in C. lemnis-catum. Another morphologically similar species, C. buckleyi, has a short advertisement call composed of 1–5 notes, and isgenetically distinct from the new species. This new Centrolene extends the known distribution of Centrolene to the south by 600 km, and is the southernmost species of this genus.

Veronica ersin-yucelii (subg. Pentasepalae, Plantaginaceae) is described and illustrated as a new species. It grows on marble rocks and screes, in one single site in Central Anatolia (Eskişehir Province), at elevations from about 1700 to 1820 metres above sea level. Diagnostic features are also given to enable comparison with the most similar species, V. caespitosa Boiss. and V. multifida L., especially regarding the indumentum, habit, inflorescence, bracts, seeds and leaves. The geographical distribution of the new species is mapped. Notes about its ecology and conservation status are also presented.
