Inflorescences terminal and axillary, 5-20 × 4-8 cm, axes terete, yellowish-green or magenta. Hypanthium 1.5-2 × 2-2.5 mm, cupuliform, fresh color unconfirmed.

Vernacular names. – “Aouteha” (Deplanche 53); “Tu” (MacKee 26591).

Notes. ‒ The specific epithet is already used in Syzygium (S. wagapense Brongn. & Gris), and the chosen replacement name is the next available name for this taxon (MCNEILL et al., 2012; Art. 6 and 41).

The diagnostic characters above are largely based on fresh material. The leaves often are strongly discolorous (dark green adaxially, yellowish-green abaxially). The secondary veins are obscure above and prominent (but not projecting) below. The branches of the inflorescence tend to diverge widely from one another.
