The University of California Department of Agriculture and Natural Resources (UCANR), has an online plant identification tool ...

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 ...

Complex morphology is an evolutionary outcome of phenotypic diversification. In some carnivorous plants, the ancestral planar leaf has been modified to form a pitcher shape. However, how leaf ...

video: Professor Miltos Tsiantis from the Max Planck Institute for Plant Breeding Research in Cologne talks about his recent work in CELL showing how genes act to determine leaf shape. view more ...

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 ...

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 ...

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 ...
