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 ...

Vein density reflects how much energy and resources the leaf has invested in the network, while distance between veins shows how well the veins are supplying resources to the leaf. The number of loops ...

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 ...

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 ...
