This undated photo shows a ginkgo leaf in New Paltz, NY. In addition to their fan shape, leaves of ginkgo trees have a unique venation pattern indicating its origin of this genus millions of years ago ...

Palms (monocots) – long narrow leaf, striate (parallel) leaf venation – adventitious roots (early development of roots derived from the shoot to compensate the roots’ limited ability to grow ...

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 ...
