A New Species

Limonium korakonisicum (Plumbaginaceae), a new species from Zakynthos Island (Ionian Islands, Greece), is described and illustrated from the only known population (locality Korakonisi) located in the southwestern coast of the island. The hexaploid chromosome number (2n=6x=51), the karyotype and the self-incompatible pollen-stigma combination A (‘A’pollen and ‘Cob’ stigma), support that L. korakonisicum is an apomictic taxon originated through hybridization. This new taxon is related to the polyploid apomictic Limonium species which are prevalent in the Aegean area and especially to the recently described Cytherian endemic L. spreitzenhoferi Erben & Brullo. The morphological differences of L. korakonisicum from L. spreitzenhoferi as well as from the sexual diploid endemic L. phitosianum, which coexists at the same locality, are discussed. Data on the ecology and conservation status of the new species are also given.

Xyliphius anachoretes, a new species of aspredinid catfish is described from the Tocantins-Araguaia River system. Xyliphius anachoretes is diagnosed by the presence of six developed retrorse serrae on posterior border of pectoral-fin spine, presence of papillae on the lower lip bearing minute branches, and only two dorsal procurrent rays. Comments about the informativeness of character-state variation among Xyliphius species and aspredinid related genera are furnished. Also, a brief discussion about conservation status of the new taxon is made.

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.

A New Species

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.

The genus Helosciadium has six species of which three have been identified in Portugal: H. nodiflorum, frequent and abundant in much of the territory, and H. inundatum and H. repens, with a scattered distribution in Portugal. In the present study, a new species, Helosciadium milfontinum, a seriously threatened plant endemic, rare and scarce that grows in the temporary ponds of the Vicentinan Coastal District is described and illustrated. Morphological characters and molecular analysis of nuclear internal transcribed spacers (ITS) and plastid regions (matK, rps16-trnK and trnL-F) confirm the existence of this new taxon. Conservation status and taxonomic relationships of the new species are examined.

A New Species

Myrcia adulterina, a new species from the Brazilian Atlantic Forest, is here described, illustrated and compared with morphologically related species. Additionally, its distribution map and a preliminary conservation status are presented. The new species is here inferred as belonging to Myrcia sect. Reticulosae due its leaves with raised venation, staminal ring densely pilose, hypanthium prolonged in a tube with glabrous inner walls and 3-locular ovaries. Within this section, the species is morphologically related to Myrcia pubipetala, from which it can be distinguished through the laxly reticulate leaf venation and thyrsoid inflorescences with all axes strongly flattened and striated when dry. Myrcia adulterina was misidentified during at least 15 years in herbaria under the name Marlierea tomentosa (currently synonym of Myrcia strigipes, a species belonging to Myrcia sect. Aulomyrcia), which is also morphologically similar. A brief discussion clarifying the morphological differences between these species is also presented.

Oreocharis brachypodus is described and illustrated as a new species from Guizhou, China. The new species is similar to Oreocharis villosa. However, the new species is readily distinguished from the latter by cymes not branched, 1–4-flowered, larger and pronounced gibbous corolla (2.2–2.5 cm long), ovary ca. 1 cm long, with 4 ribs prominent, style ca. 0.7 cm long, and thecae confluent. Comments on affinities, geographical distribution, ecology, phenology and conservation status of the new species are also provided.

Acianthera bilobulata is described and illustrated as new species. Information concerning distribution, habitat, phenology, and conservation status are provided. The new taxon is compared with the most similar species A. pubescens, from which it differs by its elliptic-lanceolate leaves, yellow-cream flowers suffused with red-purple, acute, marginally erose petals, and an oblong, obtuse, marginally entire lip with oblong, rounded lateral lobes. Furthermore, A. bilobulata is compared with other three morphologically similar species, A. breedlovei, A. henrici, and A. majakoluckae.

A New Species

Alyssum rossetii, a stenoendemic madwort discovered on a mountain slope in the Valpelline valley (northern part of the Aosta Valley in the Pennine Alps), is described here as a new species. It is a perennial that is morphologically close to the Alyssum montanum-A. repens complex, with several hitherto neglected peculiar morphological characters. Here we present a full description of the new taxon, including information on its chromosome number, genome size and ecology, as well as a detailed morphological comparison of the new species with four related taxa occuring in the broader region, namely A. flexicaule, A. montanum, A. orophilum and A. rhodanense. Besides morphological differences, the new species also conspicuously differs from the other taxa in relative monoploid genome size. According to the IUCN Red List categories and criteria, it should be classified as Endangered.
