"Abrophyllum" (Syn.: "Brachynema" F.Muell.) is a monotypic genus of flowering plants in the family Saxifragaceae "sensu lato" according to Engler, A. in Engler & Prantl and Schulze-Menz, G. K. in Melchior, 1964; placed in Subfamily Escallonioideae, Tribe Cuttsieae, it is closely related to "Cuttsia". In the APG II system "Abrophyllum" is placed in family Rousseaceae.

The sole species is "Abrophyllum ornans".Its common name is Native Hydrangea, but it does not have great affinity with the true Hydrangea.

Classification

It is also classified in Escalloniaceae (by Hutchinson 1967; Dahlgren; Thorne), Grossulariaceae (Cronquist 1988), Carpodetaceae (APG I 1998, Kubitzki 2007 [cite book|author = Gustafsson, M.H.G. (2007). Carpodetaceae. In Kubitzki, K. (Series Editor)|title = The Families and Genera of Vascular Plants| publisher = Vol.8:Kadereit, J. W. & Jeffrey, C. (Vol. Eds.). Springer-Verlag:Berlin| year = 2007| isbn = 3-540-31050-9] ), Rousseaceae (APG II 2003, Shipunov 2005, Thorne & Reveal 2007 [Thorne, R. F. & Reveal, J. L. 2007. An updated classification of the class Magnolipsida ("Angiospermae"). Bot. Rev. 73(2): 67-182.] and Heywood "et al." 2007 [cite book|author = Heywood, V. H., Brummitt, R. K., Culham, A. & Seberg, O. |title = Flowering Plant Families of the World|edition = | publisher = Firefly Books| year = 2007| location = Richmond Hill, Ontario, Canada|isbn = 1-55407-206-9] ), or even in its own family Abrophyllaceae Nakai (Reveal and Takhtajan 1997).

It is native to Australia (New South Wales and Queensland).
Habitat: warm-temperate and subtropical rainforest, especially along smaller watercourses or in gullies on poorer soils.
