Micromorphological characters supporting the removal of Senecio series Otopteri from Senecio (Asteraceae, Senecioneae) Darwiniana
Riva,Adriana; Pozner,Raúl; Freire,Susana E.
Recent molecular studies suggest that Senecio otites belonging to Senecio sect. Senecio ser. Otopteri should be removed from Senecio so that this large and taxonomically complicated genus would be monophyletic. In order to evaluate the taxonomic position of Senecio otites and the placement of series Otopteri, 13 species belonging to Senecio sect. Senecio ser. Otopteri, including S. otites, were examined for micromorphological characters of the style branches (stigmatic surface, stylearm apices) and anthers (filament collar, anther bases, anther appendages). Three states of these micromorphological characters were present in nearly all species of Senecio sect. Senecio ser. Otopteri: 1) the style-arms are apically convex or subconvex, papillate, and...

Pachyseris inattesa sp. n. (Cnidaria, Anthozoa, Scleractinia): a new reef coral species from the Red Sea and its phylogenetic relationships ArchiMer
Terraneo, Tullia I.; Berumen, Michael L.; Arrigoni, Roberto; Waheed, Zarinah; Bouwmeester, Jessica; Caragnano, Annalisa; Stefani, Fabrizio; Benzoni, Francesca.
A new scleractinian coral species, Pachyseris inattesa sp. n., is described from the Red Sea. Despite a superficial resemblance with some species in the agariciid genus Leptoseris with which it has been previously confused, P. inattesa sp. n. has micro-morphological characters typical of the genus Pachyseris. This genus, once part of the Agariciidae, is comprised of five extant species and is widely distributed throughout the tropical Indo-Pacific. It is currently incertae sedis as a result of recent molecular analysis and appears to be closely related to the Euphylliidae. A molecular phylogenetic reconstruction including P. inattesa sp. n., the genus type species P. rugosa, and P. speciosa, all present in the Red Sea, was performed using the mitochondrial...
