Pycnandra deplanchei subsp. floribunda is an endemic shrub of southern Grande Terre in New Caledonia, distributed from the Dzumac mountains to Prony. It is found in dense humid forest on ultramafic substrate at an altitudinal range 100-700 m asl. The main impact identified comes from ongoing mining activites and bushfires. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 36 and 768 km² while the number of locations is estimated to be seven, Pycnandra deplanchei subsp. floribunda is considered Vulnerable (VU) with criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) with a continuing decline of all concerned sub-criteria.
