Introduction

Levenhookia, also know as styleworts, is the genus of ten recognized species in the family Stylidiaceae and is endemic to Australia. Genus is restricted to Western Australia almost exclusively, with a few exceptions: L. Pusilla's range extends into South Australia, L. Dubia's range extends through South Australia into Victoria and New South Wales, L. Sonderi is native only to Victoria, and L. Chippendalei is also found in the Northern Territory. All species of Levenhookia possess sensitive labellum that perform similar function to columns of Stylidium species. Labellum responds to touch and enables plants to promote cross-pollination and avoid self-pollination. Most species of Levenhookia are ephemeral plants that prefer sand heath habitat. Levenhookia species also possess glandular trichomes similar to those of its sister genus, Stylidium. While no studies have been done to test Levenhookia for carnivory, it is plausible that they are carnivorous plants like related Stylidium species.
