according to this discussion,https://nargs.org/forum/viola-species-confusing-latin-names?page=1,
http://www.efloras.org/object_page.aspx?object_id=94264&flora_id=2
 and this site http://danwiz.com/Violets/Violets.php

Viola koreana is not a valid name and its synonym Viola grypoceras var exilis corresponds to another sharp leaf violet.

 finally, this viola with cyclamen leaves would be Viola variegata.
 Do you agree with this conclusion?

[Véronique Macrelle]

 this little violet on this link, I have it and it seems to me very different than Viola variegata / grypoceras / koreana ... quite miniature 3 or 4 cm in height. without stem.

it seems that it is Viola selkirkii f .variegata. I read an article that says that the green form and the variegata form coexist in the same medium

[Véronique Macrelle]

the leaves which lay flat, of what I think to be Viola selkirkii and not   grypoceras species nor variegata specie.
