 According to Dr. Atherstone, who collected in Little Namaqualand 

 in 1856, tbis species grows in the sandy fiats near the coast at Port 

 Nolloth. The leaves are succulent and very aromatic, and, mixed 

 with fat, used by the Namaquaa and Bastards as a perfume under the 

 name of "Buchu." It is called "Sab" in the Namaqua language, 

 and is dried and collected for sale.
