Distribution and ecology. – Neoarytera collina is endemic to New Caledonia, where it occurs on the southwestern coast of Grande Terre, Ile des Pins, and Maré Island in the Loyalties. It grows in sclerophyll forest on various types of substrate, in particular limestone and serpentine ( TURNER, 1995).

Notes. – TURNER (1995: 169) designated Pancher [Bois] 79 as the lectotype, since it was cited by PANCHER & SEBERT (1874: 270) as material associated to Cupania collina when they described it in their Notice sur les bois de la Nouvelle Calédonie. Original material at P is mounted on four sheets, necessitating a second step lectotypification, for which we have here chosen the most complete and best-preserved sheet [P00639111].

Six syntypes were cited in the protologue of Arytera pachyphylla: Balansa 148, Baudouin 690, Deplanche 280, 447, Pancher [Mus. Néocal.] 215, 778 and Vieillard 247. TURNER (1995: 169) cited only two of these syntypes, Baudouin 690 and Deplanche 280. Original material of these two collections at P is, however, mounted on three sheets, from among which we designate the most complete and best-preserved collection of Deplanche 280 as the lectotype [ P06598871 ].
