Summary
A study of the structure and arrangement of nuclear pores has been made in a number of species. In Selaginella kraussiana, the species investigated most extensively, the pores were arranged in a manner consistent with the view that each pore was located at the centre of an hexagonal structure lying on the nuclear surface. The significance of this arrangement and some evidence relating to the structure of the pores is discussed. In other species examined, no evidence of a regular arrangement of the pores was observed.
