- Banksia dentata (Tropical Banksia / Guibuk) – the only Banksia found in the Top End. It has distinctive serrated leaves and the characteristic banksia flower, which appears between January and April.
- Brachychiton paradoxus (Red-flowered Kurrajong / An-marrenarnak) – a small, often straggly tree that is widespread on the lowlands. It is deciduous in the dry season, when bright-red bell-shaped flowers appear on short stems from the branches.
- Buchanania obovata (Green Plum / An-dudjmi) – a medium-sized tree with large, thick leathery leaves. Bunches of green grape-sized plums appear in October to December; they are considered to be some of the best bush tucker around.
