Question
I need to identify several kinds of trees by their leaves.  for instance, the leaves are 3-5 inches in length, branched veins, fairly fine saw teeth, ovular in shape, with bark that is fairly deeply ridged.
do you need more info than that?

Answer
I can not ID the leaves from the discription you gave--it would greatly help if I knew the location of the trees--US, Asia, Southern or Western US etc. Also a picture would be great. Go to the web site www.forestry.about.com  and ask the guide--Steve Nix for help posting the picture on the Forestry Forum. If I can not ID the leaf from a picture there are other foresters on that site from different parts of the world who can help.
