Wien 107 B 209 - 220 Wien, März 2006 Taxonomic revision of the African genus Orestias RIDL. (Malaxidinae, Orchidaceae) H.B. Margonska* & D.L. Szlachetko* Abstract A taxonomic revision of the genus Orestias RIDL. (Malaxidinae, Orchidaceae) is given. A determination key as well as descriptions and illustrations of each species are provided. The new combination Orestias cardiophylla (RcHB.f.) MARC comb.n. is proposed. Key words: Orchidaceae, Malaxidinae; Orestias, Malaxis; Africa, taxonomy. Introduction While preparing the second volume of Contributions to the Orchid flora of Central West Africa (SZLACHETKO et al. 2006) various materials belonging to the representatives of subtribe Malaxidinae (Orchidaceae) have been examined. Among others the genus Orestias RIDL. has been reviewed completely. Materials and methods For the investigation materials (herbarium specimens, spirit collections, literature data and iconographies) kept at e.g.: B, BM, BR, G, HBG, K, MO, P, UPS, WAG, W and WU have been used. Results and discussion While establishing the genus Orestias, RIDLEY (1887) included to it the sole species Orestias elegans. He recognized the representatives of this new species amongst mate- rials originally determind as Microstylis stelidostachya RcHB.f. The most important and characteristic features of the new genus given by RIDLEY (1887) were: elongated column with rostellum very large, oblong, triangular to flabellate, dis- tinctly erumpent out of lateral margins of anther and locules opening laterally what is especially unique amongst closely related genera of Malaxidinae. -

Annotated Catalogue of the Flowering Plants of São Tomé and Príncipe
Bothalia 41,1: 41–82 (2011) Annotated catalogue of the flowering plants of São Tomé and Príncipe E. FIGUEIREDO*, J. PAIVA**, T. STÉVART***, F. OLIVEIRA● and G.F. SMITH+ Keywords: diversity, fl owering plants, São Tomé and Príncipe ABSTRACT A catalogue of the fl owering plants of the islands of São Tomé and Príncipe (Gulf of Guinea) is presented. Flowering plant diversity fi gures are updated to: 135 families (20 introduced), 624 genera (172 introduced), 1 104 species (301 introduced) plus 15 additional infraspecifi c taxa. At present 119 taxa (107 species and 12 infraspecifi c taxa) are known to be endemic to the two islands. The catalogue includes accepted names, synonyms used in recent literature, common names, voucher speci- mens and information on habit and habitat and on plant uses, particularly medicinally.

In The islands São Tomé and Príncipe (STP) are part the ensuing years, Exell published papers (e.g. Exell of an archipelago of four islands situated in the Gulf & Rozeira 1958) and a supplement to the catalogue of Guinea.

The freshwater and marine fish faunas of South America are the most diverse on Earth, with current species richness estimates standing above 9100 species. In addition, over the last decade at least 100 species were described every year. There are currently about 5160 freshwater fish species, and the estimate for the freshwater fish fauna alone points to a final diversity between 8000 and 9000 species. South America also has c. 4000 species of marine fishes. The mega-diverse fish faunas of South Amer- ica evolved over a period of >100 million years, with most lineages tracing origins to Gondwana and the adjacent Tethys Sea. This high diversity was in part maintained by escaping the mass extinctions and biotic turnovers associated with Cenozoic climate cooling, the formation of boreal and temperate zones at high latitudes and aridification in many places at equatorial latitudes.
