Nhu et al., Here is a paper by Mueller-Doblies that addresses the issue of "curly-whirly" morphology.

A flat linear leaf would likely have a greater heat load than a coiled or twisted surface. http://sciencedirect.com/science/article/… Dylan On 11 November 2012 11:32, Nhu Nguyen <xerantheum@gmail.com> wrote: > Hi Diana, > > Another nice post!
