We can find all kinds of leaves on our planet. Just think of tiny pine needles, fern fronds, ivy vines or a big banana leaf. My friend Eric Roalson is a professor at Washington State University who is ...

In a second experiment, Dell'Aglio et al. show that Heliconius erato prefer to lay eggs on leaves with a familiar shape, and tend to avoid laying on leaves with a shape that they have not previously ...

Francesco Vuolo and colleagues from the laboratory of Max Planck Director Miltos Tsiantis are investigating the mechanisms underlying the dazzling variation in leaf shapes one can see in nature.

Leaves come in all shapes and sizes. Scientists have discovered the simple rules that control leaf shape during growth. Using this "recipe," they have developed the first computer model able to ...

Researchers know that the variation in leaf shapes can mean big differences in a farmer's bottom line. Now, a new discovery gives plant breeders key genetic information they need to develop crop ...

The technique could be used on everything from flowers to cells to examine the factors that influence the shapes of plant parts. The story of a plant is etched in its leaves. A tree growing in a cold ...

Poison ivy can often be identified by its ‘mitten-shaped’ leaflets (pictured here) although its leaf shape can vary widely. Can you find the other poison ivy leaves in the picture? Poison ivy can ...

Watery adaptation: The structure and shape of lotus leaves growing on water (left) and above it (right) is influenced by mechanical forces. (Courtesy: F Xu/Fudan University) When the leaves of the ...

Not all the trees in this guide are native to Ireland, but most are. Our island has a small suite of native trees compared with continental Europe. The meticulous classification of each species in the ...

The story of a plant is etched in its leaves. A tree growing in a cold environment with plenty of water is more likely to have large leaves with many serrated teeth around the edges. But if the same ...
