Plaque Bark trees are one of the many organisms found on Darwin IV . Resembling trees on earth, these fauna excrete sap when pierced, and only grow in small pockets on the planet's surface. These and the Gourd Tree are the only known large fauna on Darwin IV. Also, these trees seem to be able to grow on the backs of Groveback.
The appearance of a plaque bark tree is not unlike trees on earth. The bark that grows on it takes a very simple pattern, arranging into squares and rectangles. These trees also have large branches that appear to be stirdy, being able to support Daggerwrists. No leaves or flowers seem to grow from the lower branches up to the head, and only a small amout grow from the peak of the tree.
