Syncytes occurred in a triploid and tetraploid progeny of an interspecific hybrid between Sorghum bicolor and S. halepense. That they originated by the fusion of two or more microsporocytes as a result of environmental conditions of high temperature and moisture stress is suggested. Meiosis was relatively regular in material collected from the same plants during favorable growing conditions. Coalescence of pollen mother-cells varied from complete fusion into one polyploid cell to merely peripheral connection. Although meiosis was very irregular in these fusion bodies, sufficiently regular and functional fusion bodies, sufficiently regular and functional polyploid polyploid spores could be formed which may subsequently give rise to a polyploid series within a species.
