Trees 6- 11 m. Bark unknown. Branchlets terete, sometimes slightly quadrangular, maroon. Petioles 6-19 mm, thicker at base. Leaf blades 5-13 × 2.4-4 cm, elliptic, base broadly cuneate or rounded, margins broadly sinuous, apex acute to acuminate. 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. Fruits c. 0.8-1.3 cm, globose, white or reddish at maturity. 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. Additional specimens examined. ‒ NEW CALEDONIA. Prov. Iles Loyauté: Lifu, 1865, Deplanche 53 (P [P04633326, P04633327, P04633328, P04633316]). Prov.
