Vegetation:

* Grasses: The most dominant feature are tall grasses, such as elephant grass, red oat grass, and star grass. These grasses are adapted to the dry conditions and seasonal rainfall.

* Scattered trees: Acacia trees are common, along with baobab trees, and some other species like thorn trees and eucalyptus.

* Shrubs: Smaller, woody plants like bushwillow and wild fig are also present.

Other Features:

* Soil: The soil is often red-brown due to high iron content and can be either clay or sandy.

* Water: Savannas are typically characterized by seasonal rivers and streams, which often dry up during the dry season.

* Wildlife: The savannas are home to an incredible variety of wildlife, including lions, elephants, giraffes, zebras, and many more.

It's important to note that the exact mix of vegetation and other features varies greatly depending on the location within the African savanna. For example, the savannas of East Africa tend to have more trees than the savannas of South Africa.
