Pycnandra sessilifolia is an endemic tree of New Caledonia distributed discontinuously on Grande Terre, from Massif du Tchingou to Nodela in the north and Kouakoué to Prony in the south. It is found in humid forest on ultramafic substrates at an altitudinal range of 200-800 m asl. This species is quite common, but some subpopulations are or could be impacted by ongoing and future mining activities. Therefore, Pycnandra sessilifolia is considered Near Threatened (NT).
