Citrus maxima

The pomelo , pummelo , or in scientific terms ''Citrus maxima'' or ''Citrus grandis'', is the largest citrus fruit from the family Rutaceae and the principal ancestor of the grapefruit. It is a natural, i.e., non-hybrid, citrus fruit, native to Southeast Asia. Similar in taste to a sweet grapefruit, the pomelo is commonly consumed and used for festive occasions throughout Southeast Asia. Like the grapefruit, the pomelo has the potential for drug interactions.
