 woody, top-shaped plant, known as Welwitschia, which produces 

 in its youth two leaves, and never more in its lifetime, though 

 attaining to a great age. They feed also on the Scytone?fia, a 

 moisture-storing plant, which grows only on rocks. Though 

 affecting dry, rocky regions from choice, the Anubis Baboons 

 often descend in large hordes to the cultivated country, and
