Xestospongia Muta

Petrosiidae (Haplosclerida, Demospongiae) is characterized by the hard and friable consistency, and an isotropic reticulated skeleton of oxeas/ strongyles. The Brazilian coast and oceanic islands harbor three out of four known genera of Petrosiidae: Neopetrosia de Laubenfels, 1949; Petrosia (Petrosia) Vosmaer, 1885 and Xestospongia de Laubenfels, 1932. A taxonomic survey of samples from several expeditions housed at the Porifera Collection of Museu Nacional, Universidade Federal do Rio de Janeiro, with additional comparative materials obtained from the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, and Universidade Federal de Pernambuco enabled the description of two new species: P. (P.) revizee sp. nov. and X. dorigo sp. nov. We also recorded a range extention for Neopetrosia proxima and Xestospongia muta, and Xestospongia grayi was synonymized with X. muta. Other species reported from the country are diagnosed, and an identification key for Petrosiidae from Brazil is provided.

Schinus pampeana is a new species from Brazilian Pampa. The new species was tentatively included in Schinus sect. Terebinthifolia, and is morphologically most similar to Schinus lentiscifolia and S. weinmanniifolia. We present here a detailed morphological description, a geographical distribution map, IUCN conservation status assessment, ecological data, photographs, and a table of diagnostic characters of S. pampeana and the most similar species. Schinus pampeana increases the total number of Schinus to about 49 species, of which eleven are recorded in Brazil.

High Altitude Grasslands

Sisyrinchium antemeridianum and S. flabellatum are two new species of Sisyrinchium sect. Hydastylus that occur in the high altitude grasslands of Southern Brazil, in the states of Rio Grande do Sul and Santa Catarina. Sisyrinchium antemeridianum can be distinguished from similar species by the conspicuous rhizome with remnants of old leaves and flowers with larger tepals and longer, connate filaments. Sisyrinchium flabellatum has a distinctive equitant phyllotaxis and a lax inflorescence of numerous flowers with small, typically reflexed tepals. Both species are endemic to the Highlands of Southern Brazil. Morphological descriptions, illustrations and ecological information for both plants are presented.

Pimpinella ibradiensis, an unusual new species found in the Toka Yayla (İbradı, Antalya) in southern Anatolia, is described and illustrated. Site conditions, synecology and conservation status of P. ibradiensis are considered. In light of the comparison with the other closely related four species, namely P. nephrophylla, P. flabellifolia, P. sintenisii and P. paucidentata, its similarity within the genus are discussed. P. ibradiensis is easly distinguished from its relatives by its white petals, presence of bracts and bracteoles, larger fruits (4–5.5 × 1–2 mm), and having serrulate basal leaves with 60–95 strongly cartilaginous teeth along margins. The geographical distribution of P. ibradiensis and closely related species are mapped and the identification key of those species is updated.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).
