Abstract The traditional circumscription of the genus Stonesia G. Taylor (Podostemaceae, Podostemoideae) includes three species restricted to western tropical Africa. Here, a new species, S. ghoguei E. Pfeifer & Rutishauser, is described, which represents the first Cameroonian member of the genus. There are another three Stonesia species restricted to western tropical Africa (Guinea and Sierra Leone). The genus Stonesia is characterized by capsule valves with five or seven ribs each, with the… 
Lebbiea (Podostemaceae-Podostemoideae), a new, nearly extinct genus with foliose tepals, in Sierra Leone
TLDR
A new genus of rheophytic herb from the Sewa River rapids in Sierra Leone, on the edge of extinction with a small population at a single site threatened by deposition of gravel and sand from alluvial gold and diamond mining upstream, and a planned hydro-electric dam.
Enigmatic morphology of Djinga felicis (Podostemaceae-Podostemoideae), a badly known endemic from northwestern Cameroon
TLDR
The structure and development of Djinga felicis is described using scanning electron microscopy and microtome sections and Cusset's protologue is enriched considerably.
How to get off the mismatch at the generic rank in African Podostemaceae?
TLDR
The Podostemaceae are highly enigmatic plants which are restricted to submerged river-rock habitats and the availability of new material from continental Africa prompted this new study, which proposes restricting Ledermanniella to the species of the former subgenus Ledermannilla, resurrecting Monandriella as monotypic genus, and accepting the genus name Inversodicraea.
Molecular phylogenetic analysis of Podostemaceae: implications for taxonomy of major groups
TLDR
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.
Silica bodies and their systematic implications at the subfamily level in Podostemaceae
TLDR
This study evaluates the taxonomic value of silica-body morphology in species representing the three subfamilies of Podostemaceae and concludes that there is a need for a more complete study ofsilica bodies throughout the family.
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
TLDR
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.
Describing a New Species into a Polyphyletic Genus: Taxonomic Novelty in Ledermanniella s.l. (Podostemaceae) from Cameroon
TLDR
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.
Floral structure and palynology of Podostemumweddellianum (Podostemaceae: Malpighiales)
TLDR
The presence of silica in the spathella, the apical septum in the ovary, dyads and pseudomonads, unimodal embryo sac and chasmogamous flowers with the possibility of self-pollination contribute to the characterisation of the Podostemoideae and the search for relationships among Podostemaceae and the clusioids.
Phylogeny of the clusioid clade (Malpighiales): evidence from the plastid and mitochondrial genomes.
TLDR
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
TLDR
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.

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

Developmental morphology of Ledermanniella bowlingii (Podostemaceae) from Ghana
TLDR
The structure and development of the Ghanaian species Ledermanniella bowlingii is dealt with, showing that accurate morphological analyses of African Podostemaceae are badly needed.
Morphology, Development and Regeneration of Thelethylax minutiflora, a Madagascan River-weed (Podostemaceae)
Thelethylax (2 species) is one of three podostemoid genera, which are endemic to Madagascar. This paper deals with the structure and development of T. minutiflora. Characters typical for this species
Microspore development in Podostemaceae-Podostemoideae, with implications on the characterization of the subfamilies
TLDR
The results of the present study reveal that in subfamily Podostemoideae both modes of microsporogenesis occur, exemplified by the early pollen development of two neotropical species: Apinagia latifolia and Marathrum rubrum.
A New Species of Ledermanniella (Podostemaceae) from Cameroon
TLDR
The ecology, morphology, and variation among individuals are discussed, and the new species is compared to the morphologically similar L. guineensis and L. minutissima.
Comparative anatomy of root meristem and root cap in some species of Podostemaceae and the evolution of root dorsiventrality.
TLDR
An anatomical comparison of the root apical meristems and root caps of 33 species that represent the major lineages of the Podostemaceae found evolutionary changes in the meristem preceded the specialization of external root morphologies.
