Cyathea horridula

Cyathea horridula is a species of tree fern native to western New Guinea, where it grows in montane forest at an altitude of approximately 1700 m. It is a rare plant known only from the type locality. This plant has an erect trunk up to 3 m tall or more. Fronds may be bi- or tripinnate and 1-2 m in length. The stipe is covered with spines and bears scattered scales towards the base. These scales are pale and have fragile edges. Sori are borne near the fertile pinnule midvein . They are protected by small, dark brown indusia that are saucer-like in appearance.
