Betta Bulbs?

[ICEAL]

Betta bulbs, what is it exactly?

although i think i have 2 different kind from what i bought.
2 are like long slim leaves and the other 1 has a long leaf stem and at the end is a little broad leaf.

Those are usually various species of the Aponogeton genus.

We'd need pictures to identify exactly which.
