| Cyathea
australis (rough tree fern) is one of Tasmania's three tree fern
species (all are native). It is less common than
Dicksonia
antarctica, but much more common than
Cyathea cunninghamii.
It sometimes hybridises with the latter species to produce the
plants called Cyathea Xmarcescens. It has a moderate to large
trunk (often a few metres tall and 20-30cm in diameter) that is not
fibrous. The common name (rough tree fern) refers to the trunk
with its hard persistent stalks of old leaves, not the foliage
itself, which is much softer than that of
Dicksonia. |
