Stylidium leptorhizum

Description

The majority of the Stylidium species are perennial herbs of which some are geophytes that utilize bulbs as their storage organ. The remaining small group of species consists of ephemeral annuals. Members of the genus are most easily identified by their unique floral column, in which the stamen and style are fused. The column—also commonly called a "trigger" in this genus—typically resides beneath the plane of the flower. Stylidium flowers are zygomorphic, which means they are only symmetrical in one plane. Flowers usually bloom in the late spring in Australia
