''Syzygium malaccense'' is a species of flowering tree native to Malaysia,〔 Indonesia (Sumatra and Java)〔 Vietnam, Thailand, New Guinea and Australia. It has been introduced throughout the tropics, including many Caribbean countries and territories. ''Syzygium malaccense'' has a variety of common names. It is known as a Malay rose apple, or simply Malay apple, ''jambu merah'' (Malaysian language, meaning "red guava"), ''jambu bol'' (Indonesian, meaning "ball guava"), ''nakavika'' (Bislama), Malay rose apple, Otaheite cashew and ''pommerac'' (derived from ''pomme Malac'', meaning "Malaysian apple" in French).

Jam is prepared by stewing the flesh with brown sugar and ginger.
