Art Nouveau Pitcher

I sure would appreciate some help with identifying this ceramic piece! The pitcher has an art nouveau style and an iridescent glaze. It has a green body and a red handle that fans out onto the body. The painting of the red glaze on the "leaves" is casually applied. It has a glazed base with white clay showing through a minor chip on base. The pitcher is 9" tall. There may be markings under glaze but subtle. I might see a letter M.
I picked up this piece at a thrift shop because it intrigued me. The glaze reminds me of Zsolnay, but no markings. Anybody recognize?
