Fruit drupe attached to the receptacle. In some bramble fruits (such as blackberry) the receptacle is elongated and part of the ripe fruit, making the blackberry an "aggregate-accessory" fruit. The strawberry is also an aggregate-accessory fruit, only one in which the seeds are contained in achenes. In all these examples, the fruit develops from a single flower with numerous pistils. A multiple fruit is one formed from a cluster of flowers (called an "inflorescence"). Each flower produces a fruit, but these mature into a single mass. Examples are the pineapple, fig, mulberry, osage-orange, and breadfruit. In the photograph on the right,
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.
