Ken, if you recall:
I have three plants - a very small Adenium multiflorum 'Mombassa', a " regular/common Adenium obesum, and this third plant which surely is not pure Adenium somalense, but probably some hybrid with some somalense thrown in. Perhaps!
All three flower on my deck during the Summer months, but I never have gotten seed pods on the small multiflorum, only on the other two.
I think you and others mentioned that all are Adenium obesum, the others are subspecies? So your labeling would be correct in any case.
