different forms from a wide range of families. [ 14 ] Carrot seed is an example. Aggregate fruit Aggregate fruits form from single flowers that have multiple carpels which are not joined together, i.e. each pistil contains one carpel. Each pistil forms a fruitlet, and collectively the fruitlets are called an etaerio. Four types of aggregate fruits include etaerios of achenes, follicles, drupelets, and berries. Ranunculaceae species, including Clematis and Ranunculus have an etaerio of achenes, Calotropis has an etaerio of follicles, and Rubus species like raspberry, have an etaerio of drupelets. Annona have Etaerio of berries. [ 18 ] [ dead link ] [ 19 ] [ dead link ] The raspberry , whose pistils are termed drupelets because each is like a small 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. [ 20 ] The strawberry is also an aggregate-accessory fruit, only one in which the seeds are contained in achenes . [ 21 ] In all these examples, the fruit develops from a single flower with numerous pistils. In some plants, such as this noni , flowers are produced regularly along the stem and it is possible to see together examples of flowering, fruit development, and fruit ripening. In the photograph on the right, stages of flowering and fruit development in the noni or Indian mulberry ( Morinda citrifolia ) can be observed on a single
