A seed-double eliminator and planting unit for a seeding machine have an aperture in a seed-carrying surface of a metering member of the seeding machine. A paddle is included on the metering member, the paddle extending away from the seed-carrying surface toward a seed path. At least one seed-double projection is included on the metering member between the aperture and the paddle, the at least one seed-double projection preventing retention on the metering member of at least one seed of a seed double pair.
