Floristic survey of vascular plants of the Parque Estadual da Pedra Selada, Rio de Janeiro, Brazil.

Background: The Atlantic Forest is one of the most diverse and threatened phytogeographical domains in the world. Despite that, it includes regions with poor floristic knowledge, even in protected areas. Although the importance of protected areas in conserving the Atlantic Forest hotspot is undisputed, it is necessary to recognise the floristic richness of these areas to propose effective conservation actions.

A new species and new records of (Solanaceae) from Colombia.

We describe a new species of the Geminata clade of from Colombia and provide new distributional records for two additional species, recorded here for the first time in Colombia. J.D.

(Solanaceae): a prickly novelty from the land of the sugar loaves, central Brazilian Atlantic Forest.

Gouvêa & Giacomin, , is described from central Brazilian Atlantic Forest. It is known from only three localities in Espírito Santo and Minas Gerais states, where granitic/gneissic outcrops (inselbergs or sugar loaves) are ubiquitous. The new species, here described, belongs to Solanum subgenus Leptostemonum (or the Leptostemonum clade; i.

A sticky and heavily armed new species of (Solanumsubg.Leptostemonum, Solanaceae) from eastern Brazil.

We describe a new species of spiny (Solanumsubg.Leptostemonum), endemic to the Brazilian Atlantic Forest and associated with granitic outcrops (inselbergs or sugar loaf mountains). Gouvêa & Giacomin, is morphologically similar to the poorly known Hiern, but is a heavily armed, much more robust plant with stellate-glandular indumentum.
