Bilateral flower symmetry developmental genetics in Proteaceae
Bilateral symmetry has evolved as an adaptive trait linked to efficient pollination and successful outcrossing, occurring over 170 times in angiosperms and in many plant groups relying upon the asymmetric expression of...

Aridity-related stomatal differences in a South African shrub
Plants in arid environments often have predictably different phenotypes than those in moist environments. Within species, such trait–environment associations could indicate local adaptation, yet supporting evidence is...
Maintenance of plant species cohesion despite ongoing hybridization
When species cohesion is maintained despite ongoing natural hybridisation.

Downregulation of net phosphorus uptake vs. leaf resorption
A trade-off may exist between the capacity of plants to downregulate their phosphorus uptake capacity and the efficiency of resorption from leaves in severely impoverished environments.
Fire
Picking up on my elemental theme, fire has long been considered a major influence on evolution of the angiosperms, whether natural or anthropogenic conflagrations. This incendiary interaction has not been helped by...
