Indehiscent fruit do not open at maturity in a pre-defined way, but rely on predation or decomposition to release the seeds. Pumpkin seeds are not released until the fruit is eaten or decays Peanut seeds are contained in indehiscent legume fruit
Some fruits are indehiscent, and do not open to disperse the seeds. Xerochasy is dehiscence that occurs upon drying, and hygrochasy is dehiscence that occurs upon wetting, the fruit being hygroscopic. Dehiscent fruits that are derived from one carpel are follicles or legumes, and those derived from multiple carpels are capsules or siliques. [3]
Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus Filipendula, which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. [3] An aggregate fruit that consists of follicles may be called a follicetum.
One definition of berry requires the endocarp to be less than 2 mm (3 ⁄ 32 in) thick, other fruits with a stony endocarp being drupes. [6] In marginal cases, terms such as drupaceous or drupe-like may be used. [3] [6] The term stone fruit (also stonefruit) can be a synonym for drupe or, more typically, it can mean just the fruit of the genus ...
An assortment of different caryopses. Wheat spikelet with the three anthers sticking out. Caryopsis cross-section. In botany, a caryopsis (pl. caryopses) is a type of simple fruit—one that is monocarpellate (formed from a single carpel) and indehiscent (not opening at maturity) [1] and resembles an achene, except that in a caryopsis the pericarp is fused with the thin seed coat.
A samara (/ s ə ˈ m ɑːr ə /, UK also: / ˈ s æ m ər-/) [1] is a winged achene, [2] a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent (not opening along a seam).
Merriam-Webster defines "fruit" as "the usually edible reproductive body of a seed plant." Most often, these seed plants are sweet and enjoyed as dessert (think berries and melons), but some ...
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, many dry seeds are called nuts, but in a botanical context, "nut" implies that the shell does not open to release the seed (indehiscent). [1]
