In Asteraceae the calyx is modified into a special structure called a pappus. This is often feathery and used in wind dispersal of the seed. It can range from large and conspicuous (think of dandelion seeds), or reduced to a short rim, or even absent. In some species the pappus is of scales rather than  bristles. 

Some daisies have other hairs or scales - these are not the pappus unless they are attached in a ring above the ovary.
