Abstract
DIŒCY, the separation of the sexes on to different diploid individuals, occurs irregularly throughout the higher plants. It must therefore have arisen a number of times during the evolution of this group. Thus the genetical control of diœcy is of considerable interest, particularly in regard to the differences between diœcious forms and their monœcious or hermaphroditic relatives. Little information has been available about such differences in the past; but two mimeographed papers1,2 have now been circulated, in which Dr. F. Galàn, of the University of Salamanca, describes the results of crosses between dioecious and monoecious forms of the cucurbitous plant Ecballium elaterium.
