Wild pomegranate reproduction. Buds (far left), flowers (centre left), and developing fruits (centre to far right) of the wild pomegranate tree (Punica protopunica). A fruit develops from the ovary of a flower, after it has been pollinated. The fruit contains seeds (far right), from which new plants will grow. The wild pomegranate is endemic to the Socotran archipelago of islands, meaning that it is found nowhere else. It is the only relative of the cultivated pomegranate (P. granatum). Socotra is located in the Indian Ocean at the mouth of the Gulf of Aden, 340 kilometres (km) from mainland Yemen and 250km from the coast of Somalia. (KEYSTONE/SCIENCE PHOTO LIBRARY/DICCON ALEXANDER)
