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treatment of its three published species is given, one of which is extinct, and two are threatened, however, a fourth, unpublished species exists.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.


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.

Stonesia ghoguei, Peculiar Morphology of a New Cameroonian Species (Podostemaceae, Podostemoideae)

A new species, S. ghoguei E. Pfeifer & Rutishauser, is described, which represents the first Cameroonian member of the genus Stonesia, characterized by capsule valves with five or seven ribs each.

Developmental morphology of Saxicolella amicorum and S. submersa (Podostemaceae: Podostemoideae) from Ghana

Structural diversity and developmental patterns in the Ghanaian Saxicolella species are compared with other African Podostemoideae and taxonomically used characters such as root, holdfasts, pollen, capsules, and seeds are demonstrated and discussed.

Comparative Morphology and Molecular Systematics of African Podostemaceae‐Podostemoideae, with Emphasis on Dicraeanthus and Ledermanniella from Cameroon

Important morphological transformations specific to African podostemoids include a shift from erect to inverted flowers in the spathella and unilocular ovaries arising via septum loss.

Enigmatic morphology of Djinga felicis (Podostemaceae-Podostemoideae), a badly known endemic from northwestern Cameroon

The structure and development of Djinga felicis is described using scanning electron microscopy and microtome sections and Cusset's protologue is enriched considerably.

Malpighiales phylogenetics: Gaining ground on one of the most recalcitrant clades in the angiosperm tree of life.

These data provide greatly increased support for the recent additions of Aneulophus, Bhesa, Centroplacus, Ploiarium, and Rafflesiaceae to Malpighiales; sister relations of Phyllanthaceae + Picrodendraceae, monophyly of Hypericaceae, and polyphyly of Clusiaceae.

Developmental morphology of Ledermanniella bowlingii (Podostemaceae) from Ghana

The structure and development of the Ghanaian species Ledermanniella bowlingii is dealt with, showing that accurate morphological analyses of African Podostemaceae are badly needed.

Phylogeny of the eudicot order Malpighiales: analysis of a recalcitrant clade with sequences of the petD group II intron

For the first time a deep node of the Malpighiales backbone, a clade comprising Achariaceae, Violaceae, Malesherbiaceae, Turneraceae, Passifloraceae, and a Lacistemataceae–Salicaceae lineage received significant statistical support from plastid DNA sequences.

Origin, Structure, and Interpretation of the Thallus in Hydrobryopsis sessilis (Podostemaceae)

The Indian Podostemoideae are characterized by a dorsiventral thalloid plant body, the nature of which is controversial, and lysigeny precedes the inception of endogenous secondary vegetative shoots.
