The sole species is Abrophyllum ornans. Its common name is native hydrangea, but it does not have great affinity with the true hydrangea.
It is also classified in Escalloniaceae (byHutchinson 1967; Dahlgren; Thorne), Grossulariaceae (Cronquist 1988), Carpodetaceae (APG I 1998, Kubitzki 2007[1]), Rousseaceae (APG II 2003, Shipunov 2005, Thorne & Reveal 2007[2] and Heywood et al. 2007[3]), or even in its own family Abrophyllaceae Nakai (Reveal and Takhtajan 1997).
It is native to Australia (New South Wales and Queensland). Its habitat is warm-temperate and subtropical rainforest, especially along smaller watercourses or in gullies on poorer soils. The natural range of distribution is from the IllawarraofNew South Wales to the McIlwraith Range in far north eastern Australia.[4]
Shrubs or small trees to 8 m high; leaves simple, mostly 10–20 cm long, 3–8 cm wide, alternate, large, lanceolate, long-acuminate, subserrate; without stipules, petiole 20–40 mm long. Flowers in terminal or axillary cymes, yellowish. Calyx is short (c. 2 mm long.), tubular, lobes usually 5 or sometimes 6, deciduous. Petals 4–5 mm long, usually 5 or sometimes 6, valvate, spreading, deciduous.
