Plaque-Bark Tree

The Plaque-bark Trees are the largest floral organisms on planet Darwin IV.

Biology
These towering trees have regular side branches and sparse leaves, and grow on the scarce pocket forests located near small streams and rivers, the only bodies of liquid water that can be found on Darwin IV. Their striker-nuts produce a sound similar to those made by xylophones. Dwarf plaque-barks have also been discovered.

Plaque-Bark Trees are home to the parasitic Trunk-Suckers, which feed on the tree's nourishing sap; and the predatory Daggerwrists, which prey on Trunk-Suckers.
