The spiky, iconic Canadian maple leaf. A large, lush Florida palm leaf. Thin aspen leaves rustling in the crisp Colorado air. You can probably recall many different leaf shapes from many different ...

Applied mathematicians dissected the morphology of the plantain lily, a characteristic long leaf with a saddle-like arc midsection and closely packed ripples along the edges. The simple cause of the ...

Subtle changes in genetics can have major effects on how leaves grow into a wide variety of shapes. John Innes Centre Around the globe, plants have evolved to use their leaves for many purposes: broad ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

Variation in the size and shape (physiognomy) of leaves has long been correlated to climate, and paleobotanists have used these correlations to reconstruct paleoclimate. Most studies focus on ...

Scientists have determined how key developmental genes influence growth of cells to produce such differences in leaf form. The researchers were able to make thale cress, which typically produces ...
