鉴别:
The more or less hexagonal scars that fallen fronds leave on its trunk and the exceptionally thick, black bases of the stipes are generally sufficient to identify Cyathea medullaris. Its trunk may be up to 20 m tall and about 60 cm in diameter at its thickened base, but more slender higher up. It has 20 to 30 fronds, slightly curving and from 2.5-6 m long by up to 2 m wide. The upper surfaces of the fronds are dark green and shiny and the under-surfaces pale.

一般资料:
The tallest and noblest New Zealand tree fern.
