Todea barbara (Osmundaceae) |
 |
 |
| Todea
barbara (king fern) is the only member of this genus and family
in Tasmania. It is a large and common native fern. One of
the most distinctive features of this fern is that large individuals
produce massive fibrous trunks that may be as much as a metre or
more high - these trunks are irregular in shape, unlike the
cylindrical trunks of the true tree ferns (Cyathea and
Dicksonia). The leaves are pale green and bipinnate (at least at
the frond base), and, when fertile, the undersides of the pinnules
are covered in a diffuse mass of sporangia. |
