This tree fern has smooth stems, rather than the rough stems of Cyathea australis. The brown scales at the base of the fronds are narrow, soft and hair-like in comparison to the larger scales found on Cyathea australis. The fern grows to over four metres tall, with a trunk up to 50 cm in diameter, and has fronds at least two metres long. Small circular sori are numerous on the underside of the fertile frond.
