Alectryon diversifolius, commonly named scrub boonaree or holly bush, is a species of Australian small trees of the plant family Sapindaceae.
Alectryon diversifolius grows as a shrub up to 4 m high, with simple leaves often clustered on short branchlets. Leaf shape is highly variable even on individual plants, ranging from oval to lanceolate to strongly serrated and holly-like.
The species occurs in central and south-eastern Qld and north-eastern N.S.W. Usually growing in Brigalow scrub in dark clay.
It was first described by Ferdinand von Mueller in 1858 as Heterodendrum diversifolius,[1] but was moved to the genus, Alectryon by Sally T. Reynolds in 1987.
