Its usually not a seed, just an old flower.
But many alocasia do self (as in self pollinate) so sometimes you do get seeds. If it does ripen into a seed pod there will be many seeds inside.

Thanks Bihai..so should she open the pod? to see if there are seeds inside? Also, how can she tell if they're ripe? Sorry for all the questions, but she's so exited, I'm hoping for her sake, her bloom contains seeds instead of a barrem, dead flower..Thanks, Toni

Usually if its fertile it will kind of pop open and you will see the seeds (that's what mine do). The seeds I have collected before were orange in color.

Thanks Bihai..I'll let her know..She can open the pod? check what's inside..if there's seed so be it..If not, maybe she should sow the bulb see if it sprouts.
Besides the seed question, is it better removing the stem flower has grown on? In other words, if she leaves it on, will nutrients focus on the faded flower?
For instance, like Clivia/Kafir Lily..you know how they say to remove the old flower stem? How it interfers with next years flowers?
Thanks again...Toni
