Flowers and fruit
Each flower consists of 2 white petals that are deeply divided into 2 lobes. The flower stalks are covered in short white hairs. The base of each flower contains a 2-celled ovary that is green and covered with stiff hooked hairs. Each cell contains a single tear-drop shaped seed. When mature the hooked hairs can attach themselves to animal fur or human clothing for seed dispersion.
