    Also found in: Wikipedia 0.01 sec.

Cyathea

Genus of about 600 tropical and subtropical tree ferns in the family Cyatheaceae, members of which may reach 15 m/50 ft in height. The common tree fern C. arborea is a native of tropical America and the West Indies; C. medullaris and C. dealbata both grow in New Zealand, and contain a starchy matter once used as food.

The stems characteristically show leaf scars and leaf bases and have a crown of large fronds. Older stems may be covered by masses of entangled roots that give anchorage and support.
