Cyathea insulana is a species of tree fern native to New Guinea where it grows in mossy forest and ravines at an altitude of 750-1600 m. The trunk of this species is erect 8-10 m tall and 14 cm in diameter. Fronds may be bi- or tripinnate and approximately 3 m in length. They form a spreading crown. The stipe bears thick spines as well as scales. These scales are either small pale brown with a short fringe or large and glossy brown with fragile edges.
