If you really only have an image of the leaf, perhaps you should post
your query to the Usenet newsgroup sci.bio.botany, where someone might
recognize the leaf. In your e-mail description and the image, I found
states for 11 characters in the Angiosperm Families database published
on the Internet (http://biodiversity.uno.edu/delta/angio/index.htm).
These are sufficient to exclude your tree from all but the following
families of angiosperms:
Androstachydaceae Airy Shaw
Atherospermataceae R. Br.
Cunoniaceae R. Br.
Griseliniaceae J.R. Forst. & G. Forst. ex A. Cunn.
Hamamelidaceae R. Br.
Toricelliaceae (Wang.) Hu corr. Airy Shaw
Note that some of these families (the exotic ones) are not eliminated
primarily because their descriptions in the database are incomplete,
reflecting incomplete descriptions in the botanical survey literature.
My search, including looking at your image and selecting characters,
took about 5 minutes.
If you have the leaf shown in the image, not just the image, I am sure
you could do better than this.
