Corymbia pachycarpa, commonly known as urn-fruited bloodwood, mawurru, yilanggi or warlamarn,[2] is a species of stunted tree or mallee that is endemic to northern Australia.

It has thick, tessellated bark on the trunk and branches, a crown of heart-shaped, egg-shaped or lance-shaped leaves, flower buds in groups of three or seven, white flowers and urn-shaped to barrel-shaped fruit.

Corymbia pachycarpa is a stunted tree or mallee that typically grows to a height of 6 m (20 ft) and forms a lignotuber.

The crown of the tree has sessile, heart-shaped, egg-shaped or lance-shaped leaves that are the same shade of light green on both sides, 40–120 mm (1.6–4.7 in) long and 17–50 mm (0.67–1.97 in) wide and arranged in opposite pairs.

[2][3][4][5] Corymbia pachycarpa was first formally in 1995 by Ken Hill and Lawrie Johnson.
