Dear Friends,

Just a quick note to add to this discussion---Dr. Guanghua Zhu, in his as
yet unpublished work on the Neotropical Aroid genus Dracontium, suggests the
same dispersal strategy for Dracontium, with its numerous, large bulbils
located on top of some of the species` tubers.   He suggests that wild
Peccaries (which I like ALMOST as much as I like Warthogs!) and other
animals may help to dislodge and so spread these bulbils while feeding on
the starch-filled large tubers.   Of course, these bulbils are also ideally
suited for distrubition by humans, who transport these tubers from where
they may be found to where they may travel, and when the tubers are peeled
for cooking, or are being dug, these easily detached bulbils are spread!
(Paper in prep. on this by me).



>Yes, I see the attraction between the two - the voodoo lily and the
warthog. But then wait a minute, I like them too !

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.
