What are the exact species on some these? How did you come to dogwood for your arcuate venation one. It looks like it is mixed in with a bunch of vines, but It has the arcuate venation and opposite leaves of dogwoods, but isn’t dogwood a tree. Was this a vine as it appears in the photo or young shrub or newly sprouted tree with a young twig.
