Nhu, et al.,
As I recall, petiolatum is supposed to be 2n=77 while striatum are (mostly
anyway) 2n=44. Until we all walk around with pocket DNA sequencers, we are
forced to rely on gross physical appearances. Let's not call petiolatum a
var. of striatum, and lets not call anything grown from seed "petiolatum."
That ought to serve until the aforementioned technical marvels are in a
pocket of each of us.
At least while we wait for definitive enlightenment.

Nhu, petiolatum never set any seed as it is supposed to be a natural
hybrid. Crazy offsetting is at expense of the mother bulb mass and therfore
of the flowers. Bulbs planted buried will flower regularly each spring and
still produce a small number of offsets very year.
Striatum is taller, less stocky and does produce seed and few offsets,
good sized. They had never been confused in the past until someone decided
petiolatum is a ssp. of striatum.
