Other than American invasion of Somalia, Somali pirates threatening shipping in Red Sea area and other bad press... Somalia is actually a place very rich and diverse in succulents and xeric vegetation. Ecologically dry for eons, it is an isolated succulent desert sharing common flora with Northern Africa and Canary Islands and across to the Arabian Peninsular. Other well known stapeliads - Pseudolithos, Pseudopectinaria, Whitesloanea, Edithcolea also comes that area.
Nowadays, i try as much as possible grow succulents from equatorial africa where few succulents are to be found and the lowlands of sub-tropical africa mainly Somalia, Madasgacar. Other parts of 'tropical' africa is not really true, because they are way up above sea level most of East Africa is highland and plains above 1000 m.
