''Cyathea kermadecensis'' is a species of tree fern endemic to Raoul Island in the Kermadec Islands, where it is locally common in damp, and sometimes drier, forest and scrub. The trunk of this plant is erect, slender, and up to 20 m tall. It is often covered with scars of old stipe-bases. Fronds are tripinnate and up to 4 m in length. The rachis and stipe are both brown in colouration and bear basal scales that are brown, glossy, and often twisted. Sori are borne on either side of the pinnule midvein. They are covered by hood-like indusia. Braggins and Large (2004) note that ''C. kermadecensis'' is similar to ''Cyathea cunninghamii''. ''C. kermadecensis'' should be cultivated in good humus and provided shade as well as shelter from the wind. Nevertheless, it is a hardy species that will survive full sun and slight frost. The specific epithet ''kermadecensis'' refers to the Kermadec Islands. ''C. kermadecensis'' is one of two tree fern species endemic to the islands, the other being ''Cyathea milnei''. ==References== *Braggins, John E. & Large, Mark F. 2004. ''Tree Ferns''.
