Bob, Thanks for clearing up the previous post.
Yes, I know about the 18th century plant collections, and yes, the name "Monymusk" may well be older.
However, there is the possibility that Mimulus may have been introduced as a dried herb, with seeds, before this. Along with other herbs and spices from Africa and Asia.
Thing is we could do with some written evidence.
Also I'm puzzled about why the derivation of the word "Monymusk" is unclear.
Cheers, Joy
