M. Thulin & G. Moggi (1993) Flora of Somalia 1:243-245
Plants trees, shrubs and subshrubs. Inflorescences usually iterminal corymbose cymes or panicles, bracteoles very inconspicuous, soon falling. Flowers bisexual; calyces forming a ± irregularly lobed extension to the hypanthium; petals 4, usually united and falling together; stamens many, at least twice as long as the petals; ovaries 2-celled, placentation axile; ovules numerous. Fruits berries, usually 1-seeded.
There are probably about about 500 species of Syzygium, all native to the Old World tropics. The genus has been distinguished in different ways from Eugenia or has sometimes been included in it. (See White in Fl. Zamb. 4: 193, 1978). At late as 2017, phylogenetic relationships in the group awe still too poorly determined to provide a useful framework for sorting out all the genera that have been recognized.
