The barley mutants eceriferum‐g , which have wax deficiencies in several organs, show an abnormal stomatal development as a pleiotropic effect. The main abnormalities are double and triple stomatal complexes. Minor alterations are present as extra cells that alter the normal sequence of the stomatal row and abnormal subsidiary cells that are either larger, smaller, or displaced from their normal position. These characteristics are present in the 12 independently isolated mutants of the g locus, but could not be found in any of the other eceriferum mutants studied. The morphogenetic origin and a developmental sequence for the abnormalities are postulated.
