Image of a Miconia sp. leaf, from Ilha Grande, Brazil. Some features shared by all angiosperm leaves can be observed. One is the hierarchy of the veins, signed by their radii and originating in the successive formation of veins during the growth. Another feature is the abundance of closed loops: the leaf blade is divided by the venation array into small polygonal surfaces. A model based on the existence of mechanical instabilities leads very naturally to this kind of pattern (see Laguna et al., doi:10.1371/journal.pcbi.1000055).
