Synonym Text: Jambosa Comm. ex DC., Prodr. 3: 286. 1829; Cleistocalyx Blume, Ann. Mus. Bot. Lugduno-Batavum 1: 84. 1849.
General/Distribution: A large genus consisting of c. 1200 species, distributed in tropical Africa, Asia, northern Australia, and Pacific Islands. Represented in Pakistan by 2 species.

Syzygium is quite similar to Eugenia and all its species were previously referred to it. However, nowadays, Eugenia is thought to be restricted mainly to America and Syzygium to the old World. It differs from Eugenia in having cotyledons free (not coherent), the seed coat roughish, adhering loosely or closely to the pericarp and the inflorescence mostly paniculate-cymose.
