Description
Bosistoa transversa is a small tree with dark brown smooth bark, with horizontal wrinkles and irregular blisters. The terminal buds are scaly and finely hairy. The leaves commonly have 3 leaflets, occasionally only 1 or 2. The leaflets are broad-lanceolate or elliptic, 4 to 12 cm long, the apex is shortly acuminate and the base cuneate. The leaflets are hairless and leathery, both surfaces dull and a similar colour; the main veins and net veins are very prominent and raised on the lower surface. The oil dots in the leaves are conspicuous to the naked eye and numerous; the petiole is 1 to 5 cm long, with a distinct joint at the apex. The fruit is a 1 or 2-seeded follicle about 1 cm wide with smooth transverse ribs (Harden, 2006)
Bosistoa selwynii is a synonym of B. transversa (Harden, 2006).
