S ummary In cultivation experiments with Stellaria longipes sensu lato. from Greenland, the life history has been thoroughly studied, in order to find out how female plants in this gynodioecious/gynomonoecious breeding system are favoured in relation to the hermaphrodite plants. It seems that the maintenance of the female plants is determined by a combination of differences in length of the reproductive cycle, number of flowers per plant, number of seeds per capsule, and the sex segregation in the populations. Other factors, which might be sex linked, such as the area of cotyledons and germination pattern, may be important.
