Searsia lancea commonly known as karee, karree (Afrikaans), is an evergreen, frost hardy, drought resistant tree, which can reach up to 8 metres in height with a 5 metre spread. In North America, where it is naturalized, it is known as African sumac and willow rhus.[2] It is one of the most common trees on the Highveld and in the Bushveld in South Africa, but not found in the Lowveld.
