Popis:	Summary Plastid division, presumably caused by constriction by a developing cell plate, is described as seen once in a seedling root of Xanthorrhoea thorntonii R. Tate (Monocotyledonae). Such a method of plastid division for a higher plant is novel, and may be caused either by an anomalous or a normal cell division. Similar types of plastid division have been observed in the green algae, bryophytes and lycopods with low numbers of plastids, so that it is possible that the occurrence of such a phenomenon is a rare but natural event in angiosperms. If constriction in an abnormal position of the plastid is forced by the cell wall, then heredity of the plastid derivatives may be perturbed. The involvement of the developing cell plate as an agent that might sometimes cause ‘sister’ plastids of a plastid division to go to different cells is a possibility that has, in the past, been overlooked for angiosperms.
