The neotropical trees Chorisia chodatii, C. speciosa, Tabebuia caraiba and T. ochracea show late‐acting self‐incompatibility. Accumulated ovule penetrations following self‐pollinations were similar to those in crosses. During the six to eight day period following pollination, in both selfed and crossed ovules, a resting zygote with initial development of the endosperm was formed. Up until the time of rejection of the selfed flowers, no cytological malfunctions were evident in the selfed ovules.
