What is the difference between Syzygium cumini and Syzygium samarangense?
I. Leaf differences
Syzygium cumini leaves are leathery, broadly elliptic or narrowly elliptic, about 6 to 12 cm long and about 3.5 to 7 cm wide, with rounded obtuse tips and a short point, and a broadly cuneate base that is vaguely rounded.
Syzygium samarangense leaves are thinly leathery, elliptic or oblong, 10 to 22 cm long and 5 to 8 cm wide, with obtuse or slightly pointed tips, and a narrowed base that is rounded or slightly cordate.
II. Flower differences
Syzygium cumini has paniculate inflorescences that are axillary or borne on flowering branches, occasionally terminal, reaching up to 11 cm, with short pedicels, white flowers, 3 to 5 clustered together, a conical calyx tube about 4 mm long, and 4 ovate petals about 2.5 mm long.
Syzygium samarangense has cymose inflorescences that are terminal or axillary, 5 to 6 cm long, with several small flowers, white flowers, and pedicels about 5 mm long.
