The Many

Following the recent resurrection of Sciodaphyllum P. Browne (Araliaceae) to accommodate the majority of Neotropical species formerly included in Schefflera J. R. Forst. & G. Forst., we have begun to describe the many new members of this genus documented during field and herbarium studies conducted over the past several years. Here we describe and illustrate four new hemi-epiphytic species of Sciodaphyllum from a small area of the eastern Andes in central Ecuador: the western slopes of the Cordillera Abitagua in canton Baños, Tungurahua Province, in the buffer zone of Llanganates National Park. The four new species described, all collected within a few days in an area of less than 10 km² and not known from any other locality, are S. merinoi D. A. Neill, G. M. Plunkett, Lowry & M. M. Mora, S. purocafeanum G. M. Plunkett, M. M. Mora, D. A. Neill & Lowry, S. recaldiorum Lowry, G. M. Plunkett, M. M. Mora & D. A. Neill, and S. zunacense M. M. Mora, Lowry, G. M. Plunkett & D. A. Neill. The conservation status of all four species is assessed as Vulnerable (VU D2) according to the IUCN Red List criteria.

A New Species

We describe and name a new species of poison-dart frog from the Amazonian slopes of the Andes in Manu Province, Madre de Dios Department, Peru; specifically within the Amarakaeri Communal Reserve and the buffer zone of Manu National Park. Ameerega shihuemoy sp. nov. is supported by a unique combination of characters: black dorsum with cream to light orange dorsolateral lines, blue belly reticulated with black, and the lack of axillary, thigh and calf flash marks. Within Ameerega, it shares the general appearance of A. altamazonica, A. boliviana, A. hahneli, A. ignipedis, A. petersi, A. picta, A. pongoensis, A. pulchripecta, A. simulans, A. smaragdina, and A. yungicola; each possessing a granular black to brown dorsum, a light labial bar, a conspicuous dorsolateral line running from the snout to the groin, and a metallic blue belly and underside of arms and hind limbs. From most of these species it can be distinguished by lacking flash marks on the axillae, thighs, and calves (absent in only A. boliviana and A. smaragdina, most A. petersi, and some A. pongoensis), by having bright cream to orange dorsolateral stripes (white, intense yellow, or green in all other species, with the exception of A. picta), and by its blue belly reticulated with black (bluish white and black in A. boliviana, green and blue with black marbling in A. petersi, and green and blue lacking black marbling in A. smaragdina). Its mating call also shows clear differences to morphologically similar species, with a lower note repetition rate, longer space between calls, and higher fundamental and dominant frequencies. Phylogenetic analyses based on the 16S mitochondrial rRNA fragment also support the distinctiveness of the new species and suggest that A. shihuemoy is most closely related to Ameerega macero, A. altamazonica, A. rubriventris, and two undescribed species (Ameerega sp. from Porto Walter, Acre, Brazil, and Ameerega sp. from Ivochote, Cusco, Peru). Genetically, the new species is most similar to the sympatric A. macero, from which it clearly differs in characteristics of its advertisement call and coloration. The new species is found near rocky streams during the dry season and near temporary water bodies during the rainy season. Tadpoles are found in lentic water along streams, or in shallow, slow-moving streams. Given its small geographic range, we recommend that A. shihuemoy should be considered 'Near threatened' (NT) according to IUCN Red List criteria.

Isoetes dubsiisp. nov. and I. santacruzensissp. nov., two new species from lowland areas in South America, are described, illustrated and compared to similar species. Isoetes dubsii can be distinguished from other species of the Brazilian Pantanal wetlands by a set of characters including leaves that are long, flexuous and trigonal in transverse section, tri-lobate stems, rudimentary velum, pustulate megaspores of 310‒390 µm diameter and laesurae of the megaspore at least four times wider than high. Isoetes santacruzensis has flexuous, filiform leaves, 0.4–0.8 mm wide at mid length and reaching up to 15 cm long, black or reddish-black sporangia, sclerified phyllopodia and sparsely verrucate megaspores of 320‒390 µm in diameter. We also include a key for species from the Brazilian Pantanal wetlands and Bolivia and spore images for all species that are discussed. Isoetes dubsii and I. santacruzensis are only known from their type localities and they may deserve special attention concerning their conservation status. However, based on our current knowledge on these species and according to IUCN Red List criteria, they are assessed here as data deficient (DD).

Abstract—A new species, Hymenaea jeaniana, is described and illustrated. The species is known from one of the best-sampled reserves of Amazon Rainforest, the Reserva Adolpho Ducke, in Manaus, and from protected areas of the municipality of Presidente Figueiredo, in Amazonas, Brazil. Previously, the species has been mistakenly assigned to the circumscription of the morphologically similar H. parvifolia, but differs in certain leaflet, inflorescence, and flower characteristics. The new species has a restricted distribution and is assessed as Endangered following IUCN Red List criteria. Based on herbarium collections and field studies, we present a full species description, an illustration, conservation status, and taxonomic comments. An identification key to the Hymenaea species of Brazil is also provided. There are six species of Hymenaea in the Amazon Basin, including the species described herein.

Parasopubia raghavendrae, a new species of Orobanchaceae is described from the southern Western Ghats of Kerala. It resembles P. delphinifolia and P. hofmannii var. hofmannii by its habit, shape, colour and hairiness of corolla lobes but differs by length of calyx tube, hairiness of staminal filaments and stomium, and shape and ornamentation of seeds. Parasopubia raghavendrae is hitherto known only from the type locality Mathikettan Shola National Park in Idukki district, Kerala. Detailed description of the new species along with colour photographs and comparison with its closely similar species are given. We also assessed provisionally the conservation status of the new species as Critically Endangered (CR) according to IUCN Red List Categories and Criteria.

A New Species

The limestone areas in south China are a major biodiversity hotspot for terrestrial biomes. Hemiboea, with 34 species and 5 varieties, mainly distributed in south China, is one of the characteristic plant groups in limestone areas. Hemiboeasuiyangensis, a new species of Gesneriaceae from limestone areas in Guizhou, China, is described and illustrated. The new species is easily distinguished from other Hemiboea species by having an oblique-infundibular corolla with an abaxially gibbous swelling on the upper half of the tube and with a densely villose throat and lower lobes. Hemiboeasuiyangensis is similar to H.omeiensis W. T. Wang in the shape of the leaf blade, but differs from the latter by the shape of the petiole, involucre, calyx and corolla and the colour of the corolla. The conservation status of this species is considered to be “Critically Endangered” (CR) according to IUCN Red List Criteria.

A new species of Orobanche was discovered in the Calanques National Park near Marseille, where it seems to be endemic. Its exclusive host, Staehelina dubia (Asteraceae), was never mentioned before as a host for Orobanchaceae. The new species is described here and named Orobanche staehelinae. The diagnostic characters are given in comparison with possible related species (O. kochii, O. leptantha, O. loscosii, O. canescens and O. santolinae). Its peculiar ecology (thermophilous screes, habitat of community interest) and conservation status (endangered, IUCN red list category) are presented.

Bauhinia proboscidea, a new species from Costa Rica and Panama, is described and illustrated, and compared to the closely related B. pansamalana of southern Mexico, Guatemala and Honduras. It is also compared with B. beguinotii, with which has been confused in herbaria. Bauhinia gorgonae, endemic to Gorgona Island in Colombia and which has been classified as a variety of B. beguinotii, is here considered a separate species. A key to the Neotropical species of Bauhinia with three fertile stamens is provided. Some observations on the morphology and reproductive biology of B. proboscidea are presented. Global-level assessments of the conservation status according to IUCN Red List criteria indicate that B. proboscidea and B. beguinotii (which was previously assessed using some misidentified records) should both be considered as species of Least Concern (LC), B. gorgonae should be considered as Endangered (EN), and B. pansamalana should be considered Not Threatened (NT). Country-level conservation assessments are also provided for all four species. The homology of the “intrastipular spines” of Bauhinia is briefly discussed.
