Identifying bamboo seeds?

I (my wife) purchased some bamboo seeds. I wanted the moso bamboo in a rhisome, but it was too expensive.

I have the seeds but have yet to sprout them. My concern is that it might not be moso timber bamboo, but I have an aversion to growing something in a pot indoors to start, then transplanting it outside in the ground only to discover that I got swindled.

This happened to me before. I purchased habanero seeds but some jerk sent me jalapeno seeds instead.

I understand bamboo generally takes years, possibly decades to produce seeds. Is there any way to identify the bamboo breed from the seed or from the sprouts?
