An interesting find during this evening's walk was this leaf with a peculiar color pattern. Most of the leaf had turned yellow, leaving behind patches of green between the veins.
This is one of those tree leaves that I find difficult to identify. It may be a hickory (Carya sp.). There are about 5 species that may be found in Maryland.
I don't know if this color pattern is characteristic of hickory leaves in the fall. I will look for more examples.
