The taxonomic status of Panicum sect. Tuerckheimiana and sect. Valida has remained as "incertae sedis" within Panicum. To resolve the systematic position of both sections within Paniceae s.l., morphological studies and ...

Taxonomic features of African species of Panicum sections Clavelligerae and Pectinatae are reviewed and compared with Dichanthelium and other taxa in tribe Paniceae. The new subtribe Dichantheliinae is proposed on the basis ...

The circumscription of genera belonging to tribe Bignonieae (Bignoniaceae) has traditionally been complex, with only a few genera having stable circumscriptions in the various classification systems proposed for the tribe. ...

The genus Setaria is the largest genus in the so-called bristle clade, a monophyletic group of panicoid grasses distinguished by the presence of sterile branches, or bristles, in their inflorescences. The clade includes ...

In spite of the recent studies on the phylogeny of Verbenaceae, the position of the monotypic Verbenoxylum, endemic to the Atlantic rainforest in southeastern Brazil, remains unsolved. Molecular data were here analyzed to ...

Matriz Molecular (archivo .fas) del marcador cloroplastidial ndhF y Árboles (MCCT, Consenso Estricto y ML) obtenidos de los respectivos análisis bioinformáticos realizados con la matriz molecular.

Maximum likelihood and Bayesian analyses of non-coding plastid DNA sequence data based on a broad sampling of all major Asian Begonia sections (ndhA intron, ndhF-rpl32 spacer, rpl32-trnL spacer, 3977 aligned characters, ...

We explore the evolution of polyploids in subseries Turnera, testing hypotheses on their origins using DNA sequences (partial ndhF and trnT-L) from the plastid genome, as well as sequences of the nuclear ribosomal internal ...
