One of my fascinations is a particular species of tree, the Dawn Redwood (metasequoia glyptostroboides). If you were to browse through my galleries, you may notice images that include this grand tree. Lately, I've been on a kick of studying this marvelous tree through photography. In this example, the seed cone of the dawn redwood. It has a very pleasing symmetry and delicate textures.
In fact, the whole of the dawn redwood shouts symmetry! The leaves can be distinguished from near relatives (including the bald cypress and the coast redwood) by its opposite leaf structure. And the form of a dawn redwood is that of a graceful symmetric cone.
In any case, aside from being a magnificent species, it also makes for great images!
