Cucurbitales
Pumpkins and gourds, order Cucurbitales.
The squirting cucumber (Ecballium elaterium) disperses its seeds through a process of self-dispersal known as active ballistics.12
Upon reaching maturity, the fruit utilizes an osmotic mechanismāa buildup of pressure caused by the movement of water across cell membranesāto forcibly eject its seeds. As the fruit detaches from the stem, it explosively releases its brown seeds, which can travel distances of 3 to 6 metres (about 10 to 20 feet) from the parent plant. Additionally, these seeds may be further dispersed by birds and mammals, to which the sticky seeds can adhere.123
