Austalosmunda indentata Tree FernDescription: 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” (3 genera with some 20 species of Osmundaceae are extant). 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 aesthetic tree fern trunk section that has been given a glass-like polish. The genus was discovered in 1986.
