Some plants, such as succulents, have managed to grow very plump leaves. For that to happen, according to a new study, plants had to evolve three-dimensional arrangements of their leaf veins. That's ...

You might assume that a leaf's vein patterns fork, like tree branches splitting into twigs as they get further from the trunk. But peer carefully and you'll see that the veins make innumerable closed ...

New University of Arizona research indicates that leaf vein patterns correlate with functions such as carbon intake and water use – knowledge that could help scientists better understand the complex ...

Leaf size and venation show remarkable diversity across dicotyledons, and are key determinants of plant adaptation in ecosystems past and present. Here we present global scaling relationships of ...
