There is such a thing as a separate Scots [?] language, a form of Gaelic.
Perhaps it stems from there ...

There is a case for recognising Scots (aka Lallans) as a language
separate from English, but this is a language belonging to the Anglo-
Frisian branch of Germanic. The Goidelic language of Scotland is called
Gaelic, or Scots Gaelic if you wish to distinguish it from Irish and
Manx Gaelic.

I guess I should not be surprised that it is more complicated than I
imagined. I have a "Gaelic Names of Plants" and thought this covered it. I
suppose there is a "Scots Names of Plants" as well?

I suppose this Scots is the language of "Kinmont Willie" and the like?
