description: Syzygium neolaurifolium N. Snow & Byng, nom. nov. (Fig. 1f).
Ξ Piliocalyx laurifolius Brongn. & Gris in Bull. Soc. Bot. France 12: 186. 1865 [non Syzygium laurifolium (DC.) N.P. Balakr.].
Lectotypus (designated here): NEW CALEDONIA: sine loc., Deplanche 523 (P [P00522320]!). Syntypi: NEW CALEDONIA: Kanala, Vieillard 525 (P [P00522318, P00634228, P00634229]!)
.
Shrubs to trees 3- 15 m. Bark gray or brown, rough. Branchlets terete, greenish, sometimes becoming olive-green or with some shades of magenta. Petioles 7-17 mm. Leaf blades (5.5-) 8-15 × (3.5-) 4.5-7.8 cm, elliptic or broadly elliptic to ovate, base attenuate, margins mostly flat or slightly revolute, apex broadly acute to rounded. Inflorescences terminal, axillary or ramiflorous, 1-3 × 1-2 cm, cymose to paniculate. Hypanthium 2-3 mm, cupuliform, calyptrate, apically rounded but without an umbo. Fruits to c. 5 × 5 cm, globular, pink to reddish, the surface often somewhat rough.
Notes. ‒ The adaxial leaf surface is sometimes glossy. The outer wall of the fruit can be up to c. 3 mm thick.
The epithet neolaurifolium is chosen because it is already occupied by the Bandgladeshi species Syzygium laurifolium (DC.) N. Balakr.
Two numbers are mentioned in the protologue (Deplanche 523, Vieillard 525). Of these, Deplanche 523 is represented by four sheets at P, but given three different types of labels affixed to the various sheets it is probable that they represent more than one gathering. The specimen selected as the lectotype has a red “TYPE” label affixed by previous workers and in our view is representative of the species.
