Figure 2

Overview of inflorescence and fertile flower structure. (a) Various stages of capitulum development on a branch with an opened capitulum at anthesis showing ligulate florets. Inset: capitulum with the external bracts partially removed prior to length measurement. (b) The anthers form a column through which the stylar branches and style move upward brushing the pollen grains. The stamens are attached to the ligule and the inferior ovary bears a scaly pappus. Bars (a) 1 cm, inset 1 mm, (b) 1 mm.
