Peanut seeds are contained in indehiscent legume fruit Acacia senegal fruits, in contrast, are dehiscent legume fruit Some, but not all, indehiscent fruits are included in specialized morphological categories such as achene , berry , caryopsis , cypsela , drupe , hesperidium , loment , pepo , pome , samara , syconium .
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]
dehiscence in the fruit of species of the genus is mentioned at least once; a citation which makes explicit reference to the said genus having dehiscent fruit; all or at least most of its species display dehiscence in their fruit. see also : List of plants with indehiscent fruits. Aquilegia; Asclepias; Bulbophyllum; Coopernookia; Cynanchum
A few capsules are indehiscent, for example those of Adansonia digitata, Alphitonia, and Merciera. Capsules are often classified into four types, depending on the type and location of dehiscence (see Simpson Fig 9.41 [ 2 ] and Hickey & King [ 3 ] ).
This original usage is preserved in a culinary sense, where many dry seeds are called "nuts" and come from indehiscent fruits. Almonds, cashews, pistachios, and Brazil nuts, [3] are examples of "tree nuts" that are not true nuts. Peanuts are a unique case, and grow underground from a legume. Nuts are an energy-dense and nutrient-rich food ...
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.
The indehiscent (remaining closed) schizocarps of the parsnip (Pastinaca sativa), like that of the carrot, will split into two parts. The indehiscent schizocarp of musk mallow (Malva moschata) will later split into segments called mericarps. A schizocarp / ˈ s k ɪ z ə k ɑːr p / is a dry fruit that, when mature, splits up into mericarps.
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.
