A new and unusual amphistomatic species of Tibouchina (Melastomeae, Melastomataceae) from Brazil.
Tibouchina rosanae, a new species of Melastomataceae (Melastomeae) from the state of Mato Grosso, Brazil, is described, illustrated and compared to its putative closest allied. It is characterized mainly by the inflorescence that is lax. Tibouchina rosanae is an amphistomatic species, and the presence of stomata on the adaxial leaf...Guimarães, Paulo José Fernandes ; Woodgyer, Elizabeth M.

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,... -

Notes on lichenicolous Pleosporales, with two new species, Didymocyrtis azorica and Pseudopyrenidium epipertusariae (Phaeosphaeriaceae).
The identity and phylogenetic placement of some lichenicolous Pleosporales were studied using morphological and molecular data. Two new species are described, Didymocyrtis azorica on Hypotrachyna rockii, from the Azores, and Pseudopyrenidium epipertusariae on Pertusaria pertusa, from Spain in oceanic montane woods, with a Phoma-like asexual state. This is the second...Etayo, J. ; Pino-Bodas, R.

The genus Callitriche (Plantaginaceae: Callitricheae) in South America.
Callitriche is a sub-cosmopolitan plant genus occurring throughout temperate regions of both hemispheres, including the peri-Antarctic islands, with 78 species worldwide. Records of Callitriche include frequent and extensive misidentification due to a combination of factors including a lack of taxonomic and nomenclatural clarification before the mid-20th century. This work aims...Lansdown, Richard V. ; Hassemer, Gustavo
