Tricyrtis lasiocarpa from seed

I have been sent some seeds for Tricyrtis lasiocarpa and have two questions;

1 - are these viable seeds? They look a little small to me.............






and

2 - what is the correct way to go about germinating them? I've grown Tricyrtis in the past and have always needed to give them a period of stratification. Do I need to follow this procedure again.

Thanks for reading.
