Anhedral wings will induce roll instability and improve roll maneuverability. In a large/heavy airplane with a high-wing configuration there is usually excess roll stability, so this type of wings can be pretty common.
What is the purpose of Anhedral?
The purpose of the anhedral is to get the tail surfaces away from the wing wake. The distance between the wing's trailing edge and the horizontal tail is low enough so that the tail needs a vertical offset in order to have full dynamic pressure available locally.
Why are elliptical wings better?
The elliptical wing is aerodynamically most efficient because elliptical spanwise lift distribution induces the lowest possible drag.
