The Podostemaceae are highly enigmatic plants which are restricted to submerged river-rock habitats. The availability of new material of nine taxa from continental Africa prompted this new study. Five species belonging to the genera Dicraeanthus, Leiothylax, Letestuella, Macropodiella, and Stonesia and another four species of the large genera Inversodicraea sensu stricto and Ledermanniella sensu stricto have been analysed for the first time. New anatomical and developmental data are described… 

Taxonomic revision of Saxicolella (Podostemaceae), African waterfall plants highly threatened by Hydro-Electric projects

Species of the genus Saxicolella Engl. (Podostemaceae) are African rheophytes, restricted to rapids and waterfalls as are all members of the family. Previously, Saxicolella sensu lato was shown to be

A synoptic revision of Pohliella (Podostemaceae) with notes on Aulea, Cipoia and Saxicolella

Pohliella is shown to be the correct name for the first clade of Saxicolella, and a synoptic treatment of its three published species is given, one of which is extinct, and two are threatened, however, a fourth, unpublished species exists.

Taxonomic Monograph of Saxicolella (Podostemaceae), African waterfall plants highly threatened by Hydro-Electric projects, with five new species

The genus Saxicolella Engl. (Podostemaceae) are African rheophytes, restricted to rapids and waterfalls as are all members of the family. Previously, Saxicolella sensu lato was shown to be

Molecular phylogenetic analysis of Podostemaceae: implications for taxonomy of major groups

Molecular phylogenetic analysis of matK sequences for 657 samples showed that plants of Tristicha (Tristichoideae) and of Weddellina (Weddellinoideae), which are currently treated as monospecific, had great matK differentiation equivalent to at least interspecific variation.

Describing a New Species into a Polyphyletic Genus: Taxonomic Novelty in Ledermanniella s.l. (Podostemaceae) from Cameroon

A new species of Ledermanniella s.l. is described while addressing the problem of describing a species into a polyphyletic genus with a phylogenetic approach and based on Bayesian phylogenetic inference, Inversodicraea achoundongii is described, which is inferred in a clade with I. cristata, I. ntemensis, and I. annithomae.

Evolution of unusual morphologies in Lentibulariaceae (bladderworts and allies) and Podostemaceae (river-weeds): a pictorial report at the interface of developmental biology and morphological diversification

Lentibulariaceae and Podostemaceae follow structural rules that are different from but related to those of more typical flowering plants, and the roots, stems and leaves are blurred (‘fuzzy’) but both families have stable floral bauplans.

Inversodicraea koukoutamba and I. tassing (Podostemaceae), new waterfall species from Guinea, West Africa

Two new species of Inversodicraea, I. koukoutamba and I. tassing, are described as new to science, increasing the number of species 15 known in this African genus to 32, making it the most species-diverse among African Podostemaceae.

Phylogeny of the clusioid clade (Malpighiales): evidence from the plastid and mitochondrial genomes.

This phylogeny will form the foundation for the future work investigating the biogeography of tropical angiosperms that exhibit Gondwanan distributions and is the first well-resolved, taxon-rich phylogeny of the clusioid clade.

P HYLOGENY OF THE CLUSIOID CLADE (MALPIGHIALES): E VIDENCE FROM THE PLASTID AND MITOCHONDRIAL GENOMES 1

A taxon-rich multigene phylogenetic analysis of the clusioids to clarify phylogenetic relationships in this clade and indicates that Tovomita (Clusiaceae s.s.) and Zeylanidium (Podostemaceae) are not monophyletic.

Infrafamilial Phylogeny of the Aquatic Angiosperm Podostemaceae Inferred from the Nucleotide Sequences of the matK Gene

The matK phylogenetic analyses show that Podostemaceae are composed of two major clades that correspond to the subfamily Tristichoideae sensu stricto and Weddellina and thesubfamily Podostemoideae, and may suggest that the sub family perhaps originated in America and migrated to the Old World.

Phylogenetics of Quiinaceae (Malpighiales): evidence from trnL-trnF sequence data and morphology

Optising characters of breeding system onto the molecular phylogeny reveals that bisexual flowers (Froesia) are the ancestral state in Quiinaceae, whereas androdioecy (Quiina, Touroulia) and dioecY (Lacunaria) are derived breeding systems.
