原生地・分布（英語）:

説明（英語）: Genus of 600 or more species of evergreen tree ferns, mainly from forested mountain ranges in tropical and subtropical regions of the S. hemisphere. Cyatheas may reach over 20m (70ft) tall, some relatively quickly. They have a pole-like, fibrous trunk, consisting of an erect rhizome clad in roots, topped by large, pinnate, 2-pinnate, or pinnatifid fronds, which develop in flushes; the crowns of uncurling fronds are densely covered by white, brown, or black scales. The stems bear characteristic scars of old fronds. Grow as specimen plants in a shady site. In frost-prone areas, grow in a cool, temperate, or warm greenhouse.

耐寒性（英語）: Half hardy to frost tender.
