The genus Kania Schltr. is defined and its relationship with Metrosideros Banks ex Gaertn. and Cloezia Brongniart et Gris (= Mooria Montr.) is clarified. Two new combinations are made: Kania urdanetensis (basionym Photinia urdanetensis Elmer, transferred from Cloezia) and K. microphylla (basionym Tristania microphylla Quisumbing et Merrill). The known range of Kania is extended to the Philippines and Cloezia is now considered to be restricted to New Caledonia.
