The interior of the cardonal.
A green landscape after a soaking rain. Jatropha cinerea (left foreground) seldom has so many leaves.
Some hillsides are dominated by forests of Pachycormus discolor. These trees may be well over a millennium in age. Photos taken nearly a century apart at a different location revealed almost no visible change.
