MSA May-June 2015: Geometry of Nature (1 of 4)

Here is my last minute contribution to this MSA: the geometry of nature.
I always love the forms of the wild fern branches unrolling their delicate leaves over a meter (3 feet) high.
They were a bit late this year. Probably due to a rather cold and dry spring time?
