Apart from being opposite, Syzygium cordatum leaves are also decussate, meaning that successive pairs emerge at right angles to the previous (and successive) pairs. The midribs are conspicuous and cream-coloured low down on both surfaces, receding towards their tips, as do the slightly ascending lateral veins that morph raggedly into variably visible net-veining near the margins. The entire margins in picture are creamy yellow.
The usually single-seeded, fleshy berry fruits are close to cylindrical with rounded ends or ellipsoid, maybe ovoid but wider at which end? The glossy, blackish colour when fully ripe is not convincingly dark purple. The flesh inside is white or tinged purple. Part of the short-lobed calyx persists at the fruit tip, appearing like a tiny cup. Fruit dimensions are up to 2 cm long by 1 cm wide (Coates Palgrave, 2002; Schmidt, et al, 2002; Van Wyk and Van Wyk, 1997; Pooley, 1993; iNaturalist).
