Syzygium ingens, commonly known as red apple,[2] is a species of flowering plant that is endemic to eastern Australia.

It is a medium-sized to tall rainforest tree with narrow elliptic to oblong leaves and panicles of white flowers on the ends of branchlets, followed by spherical red berries.

The five sepals are fused at the base forming a bell-shaped floral cup about 3 mm (0.12 in) in diameter with rounded lobes.

[4] In 1988, Gordon P. Guymer and Bernard Hyland changed the name to Acmena ingens in the journal Muelleria,[5][6] a name that is accepted by the National Herbarium of New South Wales.

[2] In 2006, Lyndley Craven and Edward Sturt Biffin changed Moore's name Nelitris ingens to Syzygium ingens in the journal Blumea,[7][8] the name accepted by the Australian Plant Census[1] Red apple grows on volcanic soil from near Gympie in south eastern Queensland to Casino in northern New South Wales.
