Who is amaryllis is Alice and wonderland?

Amaryllis is not a character from Lewis Carroll's "Alice's Adventures in Wonderland." It is possible that you are referring to a character from a different adaptation or retelling of the story, as various interpretations and expansions of Carroll's work have introduced new characters. In the original tales, Alice encounters a range of whimsical characters such as the Mad Hatter, the Cheshire Cat, and the Queen of Hearts, but Amaryllis does not appear in any of them.
