During the past year the writer undertook an investigation of the morphology of Richardia africana, (the ordinary Calla Lilly, otherwise known as Calla ethiopica, or Zantedeschia africana), with a view of discovering what might be found relative to its life history, and comparing its life history with that of other Aroids. In at least one respect the results were curious and unexpected.
