From what I understand about the history of cannabis' spread, South Africa is a real melting pot for genetics. It was a common stop for ships on the trade routes from Europe to India, before the canal was built. Sailors brought seeds from all over the world and planted them helter-skelter near the seaports. So look up SA strains, such as Durban Poison, the most well known of there. Also I'm thinking Swaziland, being relatively close to these seaports, would have some of its own.
