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.
The developmental morphology ofIndotristicha ramosissima (Podostemaceae, Tristichoideae)
The developmental morphology of Indotristicha ramosissima, a submerged rheophyte from South India, is described and some morphogenetic switches are postulated in order to derive it from a putative ancestor that still showed the classical root-shoot model typical of most angiosperms.

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.
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.
Djinga cheekii sp. nov. (Podostemaceae) from Cameroon
A molecular analysis revealed that D. cheekii is sister to D. felicis, and both together are sister to Ledermannilla linearifolia and L. pusilla which show completely inverted buds inside the spathella, as typical for the large and still artifi cial genus Ledermanniella.
