  author={E. L. Cabral and N. M. Bacigalupo},
The new genus Scandentia is proposed with four species; two of them are separated from Borreria sect. Galianthe: S. cymosa and S. monodon, and another two are new ones: S. andreii and S. macrobracteata. Affinities and differences with Emmeorhiza, Galianthe and Borreria are keyed out. The species are described and illustrated. 
The species of the genus Staelia (Rubiaceae) from Paraguay, a new species and new synonymous
A new species of the genus Staelia is described and illustrated from the Boqueron department of Paraguay: S. nelidae. In total, three Staelia species have been recognized for Paraguay. StaeliaExpand
Denscantia calcicola (Rubiaceae), a New Species from Limestone Outcrops in the Brazilian Caatinga
The first new species of Denscantia from the caatinga biome is described and illustrated, easily distinguished by its plicate-nerved and scabrous leaves, axillary inflorescences with 7–15 glomerules, calyx tube 0.85–1.2 mm long and pollen grains with only one endocingulum. Expand
Systematics, taxonomy and floristics of Brazilian Rubiaceae: an overview about the current status and future challenges
The present work is to offer an overall view of the most recent family classification with emphasis on the genera of Rubiaceae occurring in Brazil, and to indicate particular taxa that are still in need of phylogenetic and taxonomic studies. Expand
Palynological characters and their phylogenetic signal in Rubiaceae
The systematic usefulness of pollen morphology in Rubiaceae is discussed at the (sub)family, tribal, generic, and infraspecific levels, using up-to-date evolutionary hypotheses for the different lineages in the family. Expand
Dos nuevas especies de Staelia (Rubiaceae) con hojas ternadas del nordeste de Brasil

The phylogenetic utility of chloroplast and nuclear DNA markers and the phylogeny of the Rubiaceae tribe Spermacoceae.
IT was, despite often raised cautions of its utility at higher taxonomic levels, shown to provide the highest number of parsimony informative characters, and in partitioned Bayesian analyses it yielded the fewest trees in the 95% credible set. Expand
