We recently bought property in the mountains of Panama. On this
property there is a tree (~40' tall) with very peculiar
characteristics. Perhaps someone can help in determining if it is
truly strange or otherwise not so unusual.

This tree has two types of leaves. In some places it has broad leaves
similar to maple leaves, while in others it has elongated narrow
leaves, similar to eucalyptus. As we have seen, the leaf locations
change with time. Early in the rainy season, it had mostly the broad
leaves, but 3 months later had switched to the narrow variety.
Although there is some grouping of the leaves, they are not limb
specific and the two leaf types can be found side by side.

Can anyone help? I will worry about the exact identification later.
