Delissea argutidentata can grow up to 35 feet tall, which is much taller than other species in the Campanulaceae. The plants have a palm-like trunk topped by a round cluster of simple leaves. They previously inhabited the bottoms and slopes of old volcanic craters and could be found in the understory of Acacia koa forests.
