Some species drop the parachute from the achenes; the hair-like parachutes are called pappus, and they are modified sepals.

Dandelions are very similar to catsears (Hypochaeris).

Both plants carry similar flowers, which form into windborne seeds.

Between the pappus and the achene is a stalk called a beak, which elongates as the fruit matures.

The beak breaks off from the achene quite easily, separating the seed from the parachute.The heads are borne singly on a hollow stem (scape) that is usually leafless and rises 1–10 cm or more above the leaves.
