Dinesh ji, thank you very much for information!
It looks being at between plumosa and cristata.
My friend told me and also I saw writing on web that there are species which is being at between plumosa and cristata.
I found species called C. cristata plumosa group but photo does not match with my photo.
It might be difficult to find exact name, so I think it might be better to say "C. cristata plumosa group cv." or "C. cristata plumosa cv.". I d like to listen to your opinion.
