Three new species of Aulonemia (Poaceae: Bambusoideae) from the Brazilian Atlantic rainforestThree new Brazilian species of Aulonemia, a Neotropical woody bamboo genus, are described and illustrated: Aulonemia cincta, with its distinctive corky girdles; Aulonemia prolifera, characterized, among other Brazilian congeners, by its fimbriate leaf sheaths; and Aulonemia soderstromii, with its conspicuous cluster of spreading fimbriae. These new species all propagate by amphipodial rhiz... ...

Parental origin and genome evolution of several Eurasian hexaploid species of Chenopodium (Chenopodiaceae)Hybridization and polyploidization appear to be ubiquitous in the evolution of Chenopodium s.s., but the origin and the evolutionary history of the polyploid chenopods is still poorly understood. Phylogenetic analyses of DNA sequences of nrITS, four plastid regions, and 5S rDNA spacer region (NTS) of five Eurasian hexaploid chenopods (2n = 6x = 54), C. album, C. giganteum, C. pedunculare C... ...

A New Species of Eriosema (Leguminosae, Papilionoideae, Phaseoleae) from Mato Grosso do Sul, Brazil, with a Secretory Structure Novel to the GenusEriosema grearii, a new species for the genus (Leguminosae, Papilionoideae, Phaseoleae, Cajaninae), is described and illustrated. Similar to E. heterophyllum, it differs from it morphologically by the free (vs. joined) stipules, lax flowers distributed along the inflorescence axis (vs. congested and concentrated at its apex), inflorescences not opposite to the leaves (vs. opposite), and le... ...

A New Species of Eriosema (Leguminosae, Papilionoideae, Phaseoleae) from Minas Gerais, BrazilEriosema tozziae, a new species of Leguminosae (Papilionoideae, Phaseoleae, Cajaninae) from Minas Gerais is described and illustrated. Similar to E. defoliatum, it differs morphologically from the latter by the persistent leaves in the reproductive phase (vs. caducous in E. defoliatum) and the shorter inflorescences (10–13 cm long vs. 15–30 cm long in E. defoliatum). An identification key ... ...

Asterochloris sejongensis sp. nov. (Trebouxiophyceae, Chlorophyta) from King George Island, AntarcticaThe new species Asterochloris sejongensis sp. nov. has been collected from four localities of King George Island, Antarctica, and is described as a phycobiont of the lichen species Cladonia pyxidata and Sphaerophorus globosus. This discovery is based on morphological and molecular data obtained using light microscopy, confocal laser microscopy, transmission electron microscopy, and two mol... ...

Stephanocha nom. nov., a replacement name for the illegitimate silicoflagellate genus Distephanus (Dictyochophyceae)Stephanocha nom. nov. (Silicoflagellata, Dictyochophyceae) is herein proposed as a replacement name for the illegitimate genus name Distephanus, which is a later homonym of Distephanus, a flowering plant. The old generic description is emended, with S. rotunda as the designated type, and new combinations are made for all bona fide silicoflagellate taxa previously assigned (including those ... ...

<p><strong>The phylogenetic position and taxonomic status of the Southeast and South Asian bamboo genera <em>Neohouzeaua</em> and <em>Ochlandra</em> (Poaceae: Bambusoideae) </strong></p>Among the tropical woody bamboos, the Melocanninae is one of the most clearly recognized subtribes morphologically and has also been consistently well delimited in molecular phylogenetic work. The relationships among those genera in this subtribe, however, have been contentious because of poorly understood generic delimitations, in part due to poor specimen material or insufficiently asses... ...
