Identification: Mystery houseplant

I would appreciate help identifying this houseplant, which is unusual but easy to grow. The clusters of tiny flowers develop near the central stem. The small plant pictured is a new plant naturally reseeded in the pot of the parent plant. Interestingly, the baby plant shows stripes on its leaves, whereas the stripes have disappeared on the parent plant.

 

Looks like Euphorbia leuconeura, Madagascar Jewel.

 

Thank you for your quick and helpful reply!
