Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.
Senecioneae is the largest tribe of the Asteraceae, or the sunflower family, comprising over 150 genera and over 3,500 species.

Pieter B. Pelser is a lecturer in Plant Systematics and the curator of the herbarium at the University of Canterbury in Christchurch, New Zealand. One research interest is the evolutionary history of the tribe Senecioneae, one of the largest tribes in the largest family of flowering plants. He wrote the most recent attempt to define and delimit this tribe and its problematic founding species Senecio. He also studies insects that eat these plants (Longitarsus) which contain pyrrolizidine alkaloids and what makes them choose which plants they eat.
