Unusual seed germination

Hi Jim,  Gusman writes at page 45 : Elephas, Lobatum and Thunbergii do not produce aerial leaf during the first season, but develop tuberlets underground,

may be the seeds were hybrids with one of these species?

In my opinion you could leave them into the pots for a longer time to 
let them grow at least for three months.
Hope they will in future explain their behaviour.
