The evolution of self-fertilization towards a non-optimal population growth rate in a context of pollen limitation assuming that the evolution is driven by the Fisherian cost of outcrossing and inbreeding depression (δ) (without purging) and the pollination rate of outcrossed ovules (e). Complete self-fertilization evolves for the set of parameters below the solid line and complete outcrossing evolves for the set of parameters above the solid line. Increased growth by selfing occurs below the thin line, resulting in evolutionary rescue, and decreased growth by selfing occurs above the thin line, resulting in evolutionary suicide.
