Description
Flindersia bourjotiana is a tree that typically grows to a height of 35 m. Its leaves are pinnate, arranged in opposite pairs with between four and eight narrow egg-shaped to elliptical leaflets mostly 55–170 mm long and 15–48 mm wide, the side leaflets on petiolules 1.5–4 mm long, the end leaflet on a petiolule 10–20 mm long. The flowers are arranged in panicles 120–240 mm long and have five sepals 1–2 mm long and five white or greenish white petals 5–9.5 mm long. Flowering occurs from April to November and the fruit is a capsule 70–150 mm long, studded with short, rough points, and separating into five at maturity, and releasing seeds that are winged at both ends.
