Sunlands
From Tolkien Gateway
Sunlands is the name in Gondor and the Westlands that refers to the far southern lands, the Harad.
Samwise Gamgee heard tales of the Swertings, Big Folk of the Sunlands who rode on oliphaunts when they fight.[1]
N.B. Sunlands is not to be confounded with Sunlending, the Rohirric name of Anórien.
