Cyathea approximata is a species of tree fern endemic to Madagascar. The trunk is erect spiny and about 2 m tall. Fronds are bipinnate and usually 2 m long. They often form a crown of two whorls of about seven fronds each. Dark brown scales with a paler margin cover the stipe. Sori are round and occur near the fertile pinnule midvein. They are covered by thin brown indusia which are cup-like in appearance.
