The androecium consists of five stamens with filaments attached to the inside of the corolla (epipetalous); the anthers of the stamens are united together, and form a tube through which the style passes. (Stamens with united anthers and free filaments are described as syngenesious.) The ovary is inferior and syncarpous, consisting of two united carpels; within it is a single erect anatropous ovule.

The fruit (/, Fig. 147) is one-seeded and indehiscent with a series of longitudinal ribs on its outer surface r it is a kind of nut or achene to which the special name cypsela is given. The seed is without endosperm. Besides the disk florets and surrounding them, there is a single ring of white flowers (f) resembling narrow strap-like petals. They form the ' ray ' of the capitulum, and are termed ray florets. Each of the latter is a small unisexual (female) flower, and possesses a white corolla, the lower part of which is tubular, while the upper part is drawn out into a long narrow.
