I dug through my files for some relatives of Dracaena fragrans (some that have the same form) and found Dracaena afromontana which lives in the cooler parts of subtropical/tropical Africa[i] (Ethiopia and Tanzania)[/i]. By cooler, I mean it's a mountain plant. It's African, but prefers the higher elevations (hence its name).
There's one from the Ivory coast but the leaves are more discrete and have lots of yellow spots (wrong shape for 25r).
