| Abstract: | Abstract The seta ultrastructure in Pogonatum aloides Hedw. has been observed by electron microscopy. We have observed the conductive cells in the sporophyte of Pogonatum aloides by the transversal and the longitudinal sections moreover in transections, the cells of the parenchymatic ring have more developed plastids than the cells of the cortex. The similarities and differences in the disposition of the conductive cells within the same or in different subclasses is discussed. |
