Mating system in island populations of Vincetoxicum hirundinaria
The mating system of V. hirundinaria is examined by Leimu (pp. 107-113) in island populations located on the northern border of the species' range. The frequencies of self-fertile individuals are shown to be relatively high in all populations. The results point to a mixed-mating system. Evidence is given for a late-acting self-incompatibility system.
