With the term geocarpic, a term deriving from geocarpy, in botany we mean a fruit that ripens underground.
The term geocarpy derives from the words geo- da γεο- and γεω-, in turn derived from the Greek γῆ “earth” and carpia, coming from the Greek καρπός meaning “fruit”.
Geocarpic fruits are, for example, the peanut legume (Arachis hypogaea L.), a herbaceous plant belonging to the Fabaceae (or Leguminosae) family, native to South America and widely cultivated for its edible seeds.
Other geocarpic fruits are the capsules of the Cyclamen of the Alps (Cyclamen purpurascens Mill.) Which is an almost bushy herbaceous plant, perennial with delicate and characteristic “cyclamen” colored flowers belonging to the Primulaceae family.
Other geocarpic fruits are the siliquettes of the morisia (Morisia monanthos (Viv.) Asch.), An endemic species of the Sardinian-Corsican system and belonging to the Brassicaceae family.
