Syzygium acre is an understory rainforest tree in the family Myrtaceae that is endemic to New Caledonia.

Description

Syzygium acre is a pachycaul "palmoid" tree which grows up to 10 m (33 ft) in height. It usually has a single trunk, but may have two or three vertical branches with a rosette of enormous leaves at the top of each, with each leaf growing to 1.5 m (4 ft 11 in) in length by 38 cm (15 in) wide. The young leaves and the flowers are pinkish; the flowers are cauliflorous (i.e. growing directly from the trunk) and are about 5 cm (2 in) long, and pendant. The fruit is dark purple and fibrous.

Conservation status

As of February 2025[update], this species is regarded as endangered by the IUCN due to the species being restricted to a very small area in Grande Terre (the main island of New Caledonia), and threats to its habitat imposed by bushfires and feral pigs. The current population size is not known.
