Masons ironstone plates

Found a couple of these today. I've looked up the mark and this was used from 1813 - 1820. I can't find much reference to the pattern at all really. There is a listing on worth point with not much info. Same with invaluable and also an image on Alamy. Oh and I've just found a similar one by Ashworths called green imari. Any ideas please? I've searched for masons green imari and nothing.

Here's the potteries info about Mason's which was acquired by Ashworth: https://www.thepotteries.org/allpotters/708a.htm

 

Thanks. I understand that there maybe some overlap of patterns between the two. I just can't seem to nail this one though. Two sources call it green imari but there are others calling a completely different pattern the same as. I would have thought this pattern would be a bit more widespread but there is hardly any mention of it anywhere.
