AshicaulisDescription: Polished sections of tree fern trunks are highly prized for their beauty. Tree ferns have been Tree Fernaround since the Permian, and persist to this day, earning them the term “living fossil”. The “trunk” is composed of many vascular elements that supply the plant with water and nourishment, making for a most pleasing overall effect. This is a most unusual and rarely-seen longitudinal trunk section. It was found exposed on the outside of a large water-worn boulder, and was carefully hand-polished to bring out the feathery detail seen here. As such it is one of the few known specimens of this rare tree fern.
