Whyanbeeliaterrae-reginae is a dioecious rainforest tree with narrowly egg-shaped leaves, flowers arranged in loose groups, and fruit a more or less spherical capsule.

Whyanbeeliaterrae-reginae is a dioecious tree that typically grows to a height of up to 20 m (66 ft), its young growth covered with soft hairs.

Female flowers have six tapering sepals that are similar to each other and 1–2 mm (0.039–0.079 in) long.
