ABSTRACT:

A reproductive-biology study of Lystchtton camtschatcense Schott was carried out at two sites in central Japan. The flower was shown to be protogynous. According to the stage of anthesis, the flowers changed from female to hermaphrodite condition. Potentially, the species may be pollinated by flies (no reward found), wind or by self-pollination. The seeds are thought to be dispersed by water current or by bears consuming the fruits.
