Key to Tasmanian Dicots
1. Comesperma volubile
2. Comesperma retusum
3. *Polygala myrtifolia

* Introduced species

The Polygalaceae are represented in Tasmania by a few native species of Comesperma (mostly shrubs, but C. volubile is an almost leafless twiner). Also, a couple of species of Polygala have been naturalised. The flowers are conspicuous and asymmetrical. The Tasmanian species have five sepals - three small ones, and two large ones similar in colour to the petals and forming wings on either side of the flower. There are three petals.
