Because he is repoting...

This is realy peculiar, i have never seen something similar.
I think there are two possibilities, hybrid [natural or men made] the second is a mutation.
If it is an hybrid one of the parents in order to give this form should be either N. triandus or N. virdiflorus and the second either a tazetta or a papyraceus [if technicaly possible, depend on chromosome number].
As far as i know you do not have the first two species in the garden?
The second possibility can be a mutant of N. papyraceus but that would be easy to decide only by the typical scent of this species.
By saying 'pooped out' do you mean in the open ground or in between the bulb collection?
Off course i dont exclude any other option, it is a mystery, but if it is not yet a registrated hybrid, it might become a good commercial plant for its unique form!!
