Syzygium nervosum is a species of tree native to tropical Asia and Australia, extending as far north as Guangdong and Guangxi in China and as far south as the Northern Territory of Australia.[2] It was previously known as Cleistocalyx operculatus and also known as C. nervosum (DC.) Kosterm., and Eugenia operculata Roxb., 1832. It is a medium-sized tree of about 10 meters in height with pale brown bark and dull green leaves.

The leaves of S. nervosum are elliptical, obovate and glaborous, measuring 7–9 cm in length.

Flowers cluster as greenish white trichomatous panicles. The blossoms have 4 petals.

The 7–12 mm diameter fruits are ovoid with a concave tip and a wrinkled texture. The fruits turn purplish upon ripening.
