About

Alsophila crassicaula, synonym Cyathea ledermannii, is a species of tree fern native to Papua New Guinea and Bougainville Province in the Solomon Islands, where it is common in submontane rain forest at an altitude of 1000–3000 m. The trunk of this plant is erect and grows to about 3 m in height. Fronds may be bi- or tripinnate and up to 2 m in length. The rachis is purplish brown in colouration and usually bears basal scales. These scales range from pale, to brown, to bicoloured (brown with a dark margin). Sori are borne on each side of the pinnule midvein. They are protected by firm indusia.

On New Guinea, the altitudinal distribution of A. crassicaula ranges from 1950 to 3000 m. It grows at lower elevations in the Solomon Islands.
