- Biodiversity Info
These biomes mainly occur on the valley floor, and are dominated by Acacia karoo (camel thorn) trees and other shrub and grass species. After good rains, a common sight is the beautifully elongated flower stalks of Drimia altissima (Hyacinth family), called "Katstert" or “Maermanne” in Afrikaans. Thorny shrub species include Lycium species, Beesting bush (Azima tetracantha), Num-num (Carissa bispinosa), Asparagus species and Putterlickia pyracantha. Common non-thorny shrubs include Grewia robusta (Kruisbessie) and Polygala nayrtifolia (September bush). The Kruisbessie’s seed grows out in four berries that form a square with a cross in the middle –hence the name Cross berry, directly translated from Afrikaans. It bears a beautiful pink-purple daisy-like flower. The September bush (Polygala myrtifolia) bears pink pea-like flowers on its light green branches with leaves arranged perpendicularly to each other.
