In botany, a dry fruit that opens when ripe. It splits from top to bottom into separate segments known as valves, as in the iris, or forms pores at the top (e.g., poppy), or splits around the circumference, with the top falling off (e.g., pigweed and plantain). The spore-forming organ (see sporophyte) of liverworts and mosses is also called a capsule.

[KAP-suhl; KAP-sool] The wrapping that covers the cork and neck of a wine bottle. Historically, the favored material for capsules has been lead, but concerns over lead's safety are the basis for its replacement. Current capsule alternatives are plastic, tin, aluminum, and laminates. Frequently a capsule is referred to as a foil because of its association with a metal covering. Robert Mondavi Winery has eliminated the traditional capsule and now uses a natural-paper and beeswax cap that's attached directly to the cork-a few other wineries are using this as well.

Flowers and developing fruit capsules of the ground orchid Spathoglottis plicata

In botany a capsule is a type of simple, dry fruit produced by many species of flowering plants. A capsule is a dehiscent structure composed of two or more carpels, that, at maturity, split apart (dehisce) to release the seeds within. In some capsules, the split occurs between carpels, and in others each carpel splits open.In yet others, seeds are released through openings or pores that form in the capsule. In the Brazil nut, a lid on the capsule opens, but is too small to release the dozen or so seeds (the actual "Brazil nut" of commerce) within. These germinate inside the capsule after it falls to the ground.

Capsules are sometimes mislabeled as nuts, as in the example of the Brazil nut or the Horse-chestnut. A capsule is not a nut because it releases its seeds and it splits apart. Nuts on the other hand do not release seeds as they are a compound ovary containing both a single seed and the fruit. Nuts also do not split.

Examples of plants that produce capsules are nigella, poppy, lily, orchid, willow, cotton, and jimson weed.
