Alectryon diversifolius, commonly named scrub boonaree or holly bush, is a species of Australian small trees of the plant family Sapindaceae.

[3] Alectryon diversifolius grows as a shrub up to 4 m high, with simple leaves often clustered on short branchlets.

[4] Leaf shape is highly variable even on individual plants, ranging from oval to lanceolate to strongly serrated and holly-like.

[3][4] The species occurs in central and south-eastern Qld and north-eastern N.S.W.

It was first described by Ferdinand von Mueller in 1858 as Heterodendrum diversifolius,[1][5] but was moved to the genus, Alectryon by Sally T. Reynolds in 1987.
