It has pinnate leaves usually with five elliptic leaflets, and panicles of tiny, creamy white flowers.

Bosistoa floydii grows as a small tree that may reach 15–20 m (49–66 ft) high and has a spreading crown.

[2][3][4] Bosistoa floydii was first described in 1977 by Thomas Gordon Hartley, who published the description in the Journal of the Arnold Arboretum.

The specific epithet floydii honours the eminent Australian rainforest botanist Alexander Floyd.

[4] Five-leaf bosistoa is restricted to subtropical rainforest in the Bellinger and Orara River areas in north-eastern New South Wales, where it grows on basalt or rich alluvial soils.
