Key to Tasmanian Dicots
1. Phyllachne colensoi
2. Stylidium inflorescence
3. Stylidium armeria
4. Forstera bellidifolia
The Stylidiaceae is the trigger plant family, and is characterised by an asymmetrical fused corolla and the presence of two stamens fused to the style to form a column. Stylidium is the trigger plant, in which the column, upon irritation, moves across to trap insects as part of a pollination strategy. Species range from rosette herbs to one alpine cushion plants (Phyllachne colensoi). Most species have distinctly asymmetrical flowers, but those of Forstera bellidifolia are nearly symmetrical. One native species, Levenhookia dubia, is now considered to be extinct and is not included in this key.
