It prevailed in all the later self-fertilised generations to the exclusion of every other variety and transmitting its characters faithfully, but disappeared from the intercrossed plants owing now doubt to their characters being show repeatedly blended by crossing. The self-fertilised plants belonging to this variety were not only taller, but more fertile than the intercrossed plants; though these latter in
