[pbs] gladiolus seeds- winged or not

I have noticed that most gladiolus seeds are winged - maybe there is
a different term for it - there is a dark bump in the centre, which
is the actual seed, and then a flat rim all around it.
Some of the Eurasian ones don't have the wing, or rim. Until now,
all the South African seeds I have seen had wings, but I have just
received 16 packets from there, and G. papilio has small unwinged seeds.
Is there any taxonomic significance to this? Do they get included in
separate categories? Do they refuse to hybridize with each other?
