Re: [Aroid-l] Fiction of bullate leaves

From: "Ertelt, Jonathan B" <jonathan.ertelt at Vanderbilt.Edu> on 2016.06.26 at 13:30:10(23642) hermine - I would agree with that. The shingle leaves obviously don't pose the same risk, but as soon as the mature leaves start to have any size to them sticking out from the the tree trunk they are like sails - and their leaves are tougher than those of bananas and less inclined to tearing (thicker and more complicated veining) so the holes and serious lobes et al. are a great design to help the winds go by without pulling the plant off the side of the tree or doing serious damage to the leaves. Not bullate, but a nice design never the less. More on bullate later.

I mean, THIS is how I would have designed them. hermine >All this fuss about bullated leaves. > >What about perforated leaves?
