Oak Leaf with Split Midrib

Post by Matt Markworth » Tue Oct 15, 2013 3:55 pm

Hi All,

Here's an unusual leaf I found at Simpsonwood in GA. For scale, the notebook it's sitting on is 9 1/2" long.

I'm curious how common this may be and if anyone has other examples.

Larry, Joe,

The leaf was on the ground under what appeared to be a Northern Red. The bark had the classic "ski tracks" and the leaves remaining on the tree looked like this one, except they were normal and didn't have the split midrib. It definitely caught my eye.

Looks like a mutant red oak leaf to me.

Matt,

Very cool leaf. Thanks for posting.

Given how deeply lobed the leaf is, scarlet oak seems more likely than northern red oak.

I've never seen an oak leaf do that before. I did see a sumac with a two lobed leaflet one time. Here's a mutant white spruce cone.
