Opposite Compound leaves

This is ash, you can see the large compound leaves. Compound leaves are composed of leaflets (bit like a ladder with the rungs either side of the middle supporting stem).If you trace these compound leaves back to the twig they are in pairs as another compound leaf will come off the twig opposite it. You can also see the seed (keys).
