Stomatal structure and stomatogenesis in Azolla pinnata R. Brown.


A stoma in A. pinnata consists of a unicelled binucleate guard cell with a pore, and one or more subsidiary cells towards the proximal side. Stomatal development is of the polocytic or mesoperigenous anomocytic type except that the guard-cell mother cell fails to form 2 distinct guard cells because of restricted cytokinesis. Similarities and differences between the stoma of A. pinnata and that of the fossil lycopod Zosterophyllum myretonianum are discussed.
