The name could be a variation of Claris but it really does look like Cleris to me the way it's signed

I've looked up C Leris i.e Leris being the surname and from what I can see that seems to be concentrated in the USA. So it could originate from there perhaps.
Cleris doesn't seem to feature as a first name anywhere, so either its a spelling error?is that likely? or it's someone whose parents gave her an avant garde name to be different - I like that idea.
Paul, I'm aware poinsettias are popular the world over, but in conjunction with the chrysanthemum I was thinking that one possible avenue could be someone had made this with a Victorian 'message' for Christmas ( after what Christine said). Chrysanthemums were supposed to be for love and faithfulness and the poinsettia would be representative for Christmas so perhaps someone painted it for their husband?
I've also thought it may actually be a tray of some sort rather than a bowl, although the sides are quite high. It's a large flat piece and would work as a tray.
I've found that a book on painting glass was produced in the 19th century undated, but assumed to be around 1877 apparently:
“Practical Instructions in Enamel Painting on Glass, China, Tiles
etc., " along with Full Instructions for the Manufacture of the
Vitreous Pigments Required
By Henry James Snell.
Published in London by Brodie & Middleton.
Would anyone have any thoughts on where the large bowl/tray may have orginated from glass wise?
