Poricidal capsules dehisce through pores (openings) in the capsule, as in Papaver, the seeds escaping through these pores. Flowers and developing fruit capsules of the ground orchid Spathoglottis plicata. Examples of other plants that produce capsules include nigella, orchid, willow, cotton, and jimson weed. [2] [4]
A schizocarp / ˈ s k ɪ z ə k ɑːr p / is a dry fruit that, when mature, splits up into mericarps. There are different definitions: Any dry fruit composed of multiple carpels that separate. [1] Under this definition the mericarps can contain one or more seeds (the mericarps of Abutilon have two or more seeds [2]) and each mericarp can be either:
The ovary ripens into a three-celled capsule fruit. This fruit is fleshy, ellipsoid or almost spherical, opening by three flaps, with seeds that are light brown to white and oblong with a small appendage or tail containing substances attractive to ants, which distribute the seeds. [7] [9] The chromosome number is 2n=24. [10] [8]
Dehiscent fruits that are derived from one carpel are follicles or legumes, and those derived from multiple carpels are capsules or siliques. [3] One example of a dehiscent fruit is the silique. This fruit develops from a gynoecium composed of two fused carpels, [3] which, upon fertilization, grow to become a silique that contains the ...
A silique or siliqua (plural siliques or siliquae) is a type of fruit (seed capsule) having two fused carpels with the length being more than three times the width. [1] When the length is less than three times the width of the dried fruit it is referred to as a silicle . [ 2 ]
The fruit is a two-celled capsule, dehiscing somewhat explosively. In most species, the seeds are attached to a small, hooked stalk (a modified funiculus called a jaculator or a retinaculum) that ejects them from the capsule. This trait is shared by all members of the clade Acanthoideae.

The sandbox tree's fruits are large, pumpkin-shaped capsules, 3–5 cm (1–2 in) long, 5–8 cm (2–3 in) diameter, with 16 carpels arranged radially. Its seeds are flattened and about 2 cm (3 ⁄ 4 in) diameter. The capsules explode when ripe, splitting into segments and launching seeds at 70 m/s (250 km/h; 160 mph). [5]
