Cibotium barometz grows like a tree, with a woody, thick rhizome covered by long brown hairs.

The leaves are divided into a petiole and a leaf blade. The relatively thick and often over 1 meter long petioles are triangular in cross section at their base and densely covered with pressed, 10 to 15 millimeter long hairs. The 1.5 to 3 meter long leaf blade is double-pinnate. The first-order feathers are 40 to 80 centimeters long and 15 to 30 centimeters wide. The leaflets are pointed and slightly notched to serrate on the edge. The sori sit on the edge of the segments of the leaflets. The spores are pale yellowish.

The number of chromosomes is 2n = 136.
