Abstract Crataegus species (Rosaceae) or hawthorns form dense thickets and displace native vegetation out of their range. In South Africa, monogyna C. mexicana are under surveillance but there is lack information on pollination ecology. Therefore, this study sought to investigate the mechanism potential insect pollinators these plants. Pollinator exclusion experiments were conducted ten plants ...
