Leaf shape is a wonderful illustration of diversity, for the range of existing morphologies is strikingly high. Even more, leaves prove evolutionarily labile characteristics as these organs may prove dramatically different between closely related species. Detailed reasons for such diversity is not yet completely documented of course, for there are probably plenty, maybe there is even a specific explanation to each individual shape. Or maybe such an evolutionary repertory could result from drifting developmental pathways without adaptive explanation. Both processes may also be involved but today, we stand to an adaptive story: the amazing drip tip adaptation of acuminate leaves.
