Key to Tasmanian Dicots
Restionaceae 4b:37
Although the wire sedges (Restionaceae) are not particularly diverse in Tasmania, with only 14 native species in 11 genera, they are a conspicuous and ecologically important group. They are one of the dominant families (along with Cyperaceae) in sedgeland vegetation.

The obvious characteristic of the family is that the leaves are reduced to scales that sheath the stem. Most species have many of these scales, and the plants are wiry. The flowers are reduced and in inflorescences (as in the related families Cyperaceae, Poaceae, Centrolepidaceae and Juncaceae). Unlike Poaceae, Centrolepidaceae and Cyperaceae, and like Juncaceae, the flowers have petals and sepals (although these are small and dry).

A couple of species of Cyperaceae can be confusied with Restionaceae. These include Caustis pentandra which also has wiry stems with multiple scale leaves, and Baumea juncea which has erect slender stems with scale-leaves.
