N1 - Development of morphological and physiological mosaics in the Loranthaceae and Viscaceae familiesThe histories of development of N nytsia floribunda and Viscum album are compared Both plant species showmorphologicalpenetrations called mosaicsN uytsia floribzmda develops a morphological mosaic by penetration of root and shoot materials and a physiological mosaic in the blossom where postflorally the inflorescence axes become green again continue growing vegetatively and form the next inflorescences from this regionViscam album develops a morphological mosaic from the blossom material and pedicle in the case of the female plant and from the perianth and microsporophylls stamen in the case of the male In the region of the root Viscam album develops a physiological mosaic instead of a root the mistletoe forms a vertical primary haustorium at its basal part with longitudinal bark strands originating from it organs sui generis developing secondary haustoriums sinkers penetrating the bark of the host tree From these organs new vegetative shoots may ariseThese mosaic formations correlate with extreme growth forms Viscum album developswood tissuewithin the shoot and reduces its size to that of annual plants Naytsia floribanaa however develops a shoot parenchyme and grows to the size of a tree In the case of Naytsia floribunda the polar mosaic formations correlate with the shape of an annual herb having enlarged to the size of a tree In the case of Viscam album these polar mosaic formations correlate with the shape of a tree having reduced to the size of an annual herbnbsp
