Appearance

In extremely arid conditions, it may occur as a small, wiry bush. It grows up to 21 m in height. The tree carries leaves that grow to approx. 2.5 cm in length with between 4 and 10 pair of pinnae each with up to 15 pairs of leaflets. Flowers are small and white, highly aromatic, and occur in tight clusters. Seeds are produced in pods which are flat and coiled into a springlike structure.

The plant is known to tolerate high alkalinity, drought, high temperatures, sandy & stony soils, strongly sloped rooting surfaces, and sand blasting. Also, plants older than 2 years have been observed to be somewhat frost resistant.

Some say their flat tops and ever-thinner branches in the top are a result of how Giraffes feed on the tree. These were found in a very special place, the edge of the Ngorongoro crater floor.
