Fruit anatomy Fruit anatomy Fruit anatomy is the plant anatomy of the internal structure of fruit. Fruits are the mature ovary or ovaries of one or more flowers. In fleshy fruits, the outer layer (which is often edible) is the "pericarp", which is the tissue that develops from the ovary wall of the flower and surrounds the seeds. But in some seemingly pericarp fruits, the edible portion is not derived from the ovary. For example, in the fruit of the ackee tree the edible portion is an aril, and in the pineapple several tissues from the flower and stem are involved. The
Grey-green fruit dove Grey-green fruit dove The grey-green fruit dove ("Ptilinopus purpuratus") is a species of bird in the family Columbidae. It is endemic to the Society Islands in French Polynesia. Its natural habitat is subtropical or tropical moist lowland forests. The grey-green fruit dove is endemic to the French Polynesian islands of Tahiti and Mo'orea. There is an estimated population of 5,000 to 10,000 mature individual birds on the two islands, of which 5,000 - 6,000 live on Mo'orea, at an estimated density of 2-3 birds per hectare. In 1907, the grey-green fruit dove was reportedly very abundant on the two islands.
