Plant native to Asia whose edible seeds are ground into flour for pancakes and noodles?

The plant you're describing is likely buckwheat.

While buckwheat is not technically a grass (it belongs to the knotweed family), it's often considered a pseudo-cereal due to its similar uses.

Here's why buckwheat fits the description:

* Native to Asia: Buckwheat originated in the Himalayas and spread throughout Asia.

* Edible seeds: Buckwheat seeds are the part used for flour.

* Flour for pancakes and noodles: Buckwheat flour is a staple ingredient in many Asian cuisines, used for making pancakes (like soba noodles in Japan), dumplings, and other dishes.
