Systematics and evolution of the Triodia basedowii species complex (Poaceae: Chloridoideae)

Through classifying units of biodiversity and inferring their relationships, systematists gain insight into evolution. My thesis involved a biosystematic investigation of a group of grasses found only in Australia. These grasses, commonly known as "spinifex" are a dominant part of the vegetation in the arid zone and targets for restoration, particularly in the Pilbara. I used traditional and new technologies to determine how many species were in the group and how they were related, with implications for their evolution As a result. I will name and describe eight new species, assisting efforts to protect them and restore ecosystems.
