The size, shape, and quantity of holes in each leaf can vary greatly depending on the species and can even vary greatly within a given species. Perforation is caused by sections of leaf ceasing cell growth or by dying during an early stage in the development of the leaf. These deformations that are

It is not fully known what evolutionary purpose perforation serves, but there are several possibilities. Perforation could serve the purpose of reducing the variations in growth rate, minimize chances of leaves tearing in high winds or it could help to maximize the amount of rain able to reach the

plant's roots. It could also help to cool the plant by producing turbulence around the leaf. Another possibility is that perforation is a defense against herbivory. The holes might make the leaf look less enticing to herbivores. This, however, is unlikely in relation to
