Can anyone identify this plant (from Madagascar) please?

This probably isn't a fruit, but I got some seeds from it while in South Africa.
Anyone know what it is?  Supposedly from Madagascar?

Looks like Euphorbia lophogona, and yes, is not a fruit and is from Madagascar. You can propagate from cuttings; treat like a frangipani and allow cut to callous for a few weeks before planting. Watch out for the white latex though, as is poisonous and will burn.
I used to have a small selection of plants from Madagascar - really cool looking plants, and not too hard to care for. Then the fruit tree bug bit...

Thanks!
