Doubly-compound leaf examples? I've got a project where we collect leaves, classify them, etc. There are some required classifications. One of the requirements is to get a doubly-compound leaf. What are some trees that are doubly-compound? Please help! I have Hickory, but that's just compound I think. Edit: I did try googling, but it's hard for me to know what's available in my region. **From Comments:** _I live in Tennessee, U.S._

**_Albizia julibrissin_ (Persian silk tree)** is doubly compound (AKA **_bipinnate_** ) and has a conspicuous pink/white fluffy flower. This tree is an Asian native, but it's a commonly cultivated (and equally commonly escaped) plant in the U. S. You should be able to find it in numerous locations. Look in yards and along roads.

For native species: **_Gleditsia triacanthos_ (honeylocust)** is a fairly widespread (though uncommon) example of bipinnate leaves. Here is an image from Will Cook's wonderful website:
