Unknown Engraved Water Goblets - 19th century (?)

Update - These were identified as most likely made by the Boston & Sandwich Glass Company in the nineteenth century. The pattern is called Bee and Wheat.

I bought five of these stems online. Their provenance was not identified, but I loved the detail. The engraving includes ferns, grass, other plants and curious bees. I have floated this image to a couple antiquers, one in England and one in France. Both suggest that the stems are 19th century, European, but I don't know anything more.

I would love to identify these stems. If anyone has any information to share I would be grateful.
