Abstract
Observations of development in the nonaperaturate pollen of Canna generalis Bailey, based upon light and electron microscopy, indicate that the inner intine of this species is initiated by plasmalemmasomes originating at widely separated areas of the cell surface.The intine is that part of the pollen wall located between the sporopollenin exine and the cytoplasmic surface. It is often interbedded with the exine but is not itself composed of sporopollenin. In appearance and composition, the intine is comparable with the primary plant cell wall and has been characterized by Roland as an amorphous matrix of pectins with infrequent microfibrils.
