Weird looking eophylls, Virus?

Last year I grew some A. taiwanense seedlings from SeedEx ( JB the
donor ) , they didn't show any of the characters you mention, the
tubers ( 6 from 10 seeds )  were fine at the end of the growing
season, I would suggest to take them far off from the site where you
keep other seedlings, watch them carefully and try to take some
pictures ( macro in this case ) of the leaflets in different days,
upper and lower page.

May be Jim Mc Clements will help in a diagnosis...
