This was exactly the explanation that Rod and Rachel Saunders of
Silverhill Seeds (South Africa) gave me, when they visited here, for the
incredible numbers of tiny cormlets produced by some of the Drakensberg
irids I grow (tritonia, gladiolus, etc). I don't remember which rooting
herbivores they have there, but it's exactly as Bonaventure says: the
animals eat the large corms and spread the tiny ones around.
