THE WANDERING TAPETAL NUCLEI OF ARISAEMA 
F. L. Pickett 
The fact that in certain of the higher plants the walls of the tapetal 
cells break down and allow the nuclei and cytoplasm to ''wander" 
among the developing microspores has been repeatedly noted. In 
the recent paper on wandering tapetal nuclei, Juel (1915) has carefully

reviewed the findings of earlier workers and made important criticisms 
upon their reports. The great advance in technical methods has made 
it advisable to go carefully over the ground covered by Strasburger
