That's interesting.  I actually tried germinating part of the seed at room
temperature, and the remainder in the refrigerator.  Both ended up looking
like the Ipomoea pandurata seed on the wiki, only more hairy.
In The Random House Book of Bulbs, Phillips and Rix state that T. speciosum
blooms in January and February in the wild, which I figured would be the
"dry" season (summer) in southern Chile.  Thus, the seed should ripen in
time for the autumn and winter rains.
Maybe I just had two batches of very old seed.  It's a moot point now,
since I doubt that T. speciosum would survive a Georgia summer (unless I
get an air conditioned greenhouse like the one at the Atlanta Botanical
Garden.)  I originally tried growing these when I was living in central
