Additions and supplementary notes to a revision of Australian Loranthaceae published by the present author in 1966 are presented. Six species, Decaisnina congesta, Lysiana filifolia, Amyema dolichopodum, Amyema microphyllum, Amyema subcapitatum and Amyema tridactylum, are described as new. Three subspecies, Decaisnina brittenii subsp. speciosa, Decaisnina petiolata subsp. angustata and Amyema congener subsp. diver gens, are described as new. One variety, Amyema bifurcatum var. eburnum, is described as new. Two genera, Cecarria and Dactyliophora, are recorded as new for Australia, where each is represented by one species. One other species, Amyema friesianum, is recorded as new for Australia. Change of rank of two taxa necessitate the following new combinations: Lysiana maritima and Dendrophthoe acacioides subsp. longifolia.
