An enlarged circumscription of Bifrenaria (Orchidaceae: Maxillariiinae).
A revised delimitation of Bifrenaria broadens the genus to include the previously accepted genera Guanchezia, Horvatia, Hylaeorchis, Rudolfiella, Scuticaria, and Teuscheria. These genera as currently circumscribed are changed to sections, and their respective species transferred or combined along with newly synonymised species. Bifrenaria sect. Stenocoryne and B. sect. Adipe are...Meneguzzo, Tniago E. C. ; Chase, Mark W.

A new species of Gomesa (Oncidiinae, Orchidaceae) from inselbergs in Brazilian caatinga: morphological and karyological evidence.
We describe a new species of Gomesa (Oncidiinae, Orchidaceae), Gomesa caatingana, with restricted distribution on caatinga inselbergs in Paraíba and Pernambuco States, Brazil. Morphological and karyological characters of the new species were compared with those of Gomesa flexuosa, which is morphologically the most closely related species. Differences in geographical distribution,... -

From the frying pan: an unusual dwarf shrub from Namibia turns out to be a new brassicalean family
Tiganophyton karasense, an evergreen dwarf shrub, is described as a new species. A new genus and family are also proposed for it in the order Brassicales. Phylogenetic analysis of DNA sequence data indicate that Tiganophyton is sister to Bataceae/Salvadoraceae, and all three sister to Koeberliniaceae. First realized to be undescribed... -

Ninety-three new combinations in Euploca for species of Heliotropium section Orthostachys (Boraginaceae sensu APG)
Many new combinations are needed in Euploca, previously regarded as Heliotropium section Orthostachys, to correspond with results of our forthcoming, world-wide, molecular phylogenetic analysis. We also need these names for our many δ13C determinations that identify many Euploca species exhibiting C4 photosynthesis and show that other Euploca species are not...Frohlich, Michael W. ; Thulin, Mats ; Chase, Mark W.
