Phap Leeanum - Multiple blooms per plant

[rbarata]

I thought this primary hybrid blooms with a single flower per plant but it seems that's not true.
In the pot I have two plants but I noticed they have, at least, 3 sheaths plus two more that also seems to be but as they are still small I cannot be sure.

Some photos bellow (including one from last blooming season)
These plants need to be reppoted but, as I'm lazy (sometimes) I'll wait until the blooms die (considering that they have been lasting for at least 3 months, I'll wait for spring to do it).
