AbstractAnnonaceae flowers are protogynous and mostly have loosely enclosed pollination chambers that are often associated with beetle pollination. Unlike many other species having a receptive period of several days, field studies of the genera Goniothalamus, Dasymaschalon and Desmos reveal that they have short receptive periods of 23–26 hours. Trapping mechanisms have evolved independently in Goniothalamus and Dasymaschalon. Beetles are unable to leave the flowers until the end of staminate phase, which coincides with the onset of the pistillate phase of other flowers. Desmos chinensis, which is closely related to Dasymaschalon and which also has a short receptive period, does not show an equivalent …
