Cyathea capensis, with the common name Forest tree fern, is a regionally widespread and highly variable species of tree fern.
This fern is the only member of the family Cyatheaceae native to both Africa and the Americas. The species is divided into two subspecies:
Cyathea capensis subsp. capensis is native to the Old World tropics in Africa. It is found in Malawi, Mozambique, Tanzania, Swaziland, Zimbabwe, and South Africa (from the Western Cape province to KwaZulu-Natal and Mpumalanga).
It grows in shaded moist forest along rivers and beside waterfalls, at altitudes of 360–1,820 metres (1,180–5,970 ft). The specific epithet capensis refers to the Cape of Good Hope in South Africa, where the type specimen was collected.
Cyathea capensis subsp. polypodioides is native to the New World tropics in South America.
It is endemic to southeastern Brazil in montane Atlantic Forest habitats, at altitudes of 900–2,000 metres (3,000–6,600 ft).
Cyathea capensis (both subspecies) has an erect trunk is up to 4.5 metres (15 ft)tall, occasionally even 6 metres (20 ft), and about 15 cm in diameter.
Fronds are pinnate and 2-3 m in length. The lowest pinnae may be separated from the others along the rachis and form a clump around the crown, similar to the "wig" of Cyathea baileyana. The rachis is smooth to slightly warty and covered in scales that range from tan to brown or dark brown.
