Ophiocaryon is a lesser-known genus in Sabiaceae, hitherto without detailed floral study and with unknown pollination mechanisms. Thaowetsuwan et al. examined floral morphology and anatomy revealing several unusual characters: conical cells on petals different kinds of orbicules in anthers stomata on nectary appendage tips and ovary two distinct surface patterns on stamens and ovary tanniferous […]

Feather mosses serve as important regulatory organisms for many ecological processes in boreal forests. They are generally considered to be ectohydric species, transporting water on the surface of the plant. But is this really so? Sokołowska et al. investigate their stem tissue traits and ability to transport solutes via food-conducting cells internally under modified environmental […]

A closer look at the flowers of Geraniaceae and Hypseocharitaceae reveal organs coming together to produce something new.

Investigations of Primula oreodoxa have revealed several features that differ from classic textbook descriptions of heterostyly based on P. vulgaris.

They may look like extra-floral nectaries, but the galls in some South American trees are evidence of wasps calling in some help to look after their young.

From the perspective of vegetation regeneration, changes in bud bank density and composition along the climatic gradient could be crucial for the prediction of plant community composition and dynamics under future climatic scenarios.

Even though silica and lignin can provide comparable stiffness, they cannot be considered as structural equivalents due to contrasting hydrophobicity.

This study answers one of the last remaining big questions in grass taxonomy while highlighting examples of convergent evolution in an ecologically important trait, the hygroscopic, twisted geniculate awn.

This study provides strong evidence, based on DNA sequences from two genomic compartments (plastid and nucleus) and morphology to group the Utricularia sect. Orchidioides into the sect. Iperua.

Self-shading may explain heteroblasty, a sudden change in form found in many angiosperms.

Unusual nuclei, with spindle-like tubular projections, in the placental tissue of Utricularia nelumbifolia may be involved in nucleus-to-cell-to-cell communication.

Why are anthers where they are? A new study finds there might be more to anthers than purely functional tools.
