Raikless (reckless) Primulas

I have to admit Raiklesses is not a common name I’d heard before. I was looking up the Dictionary of the Scots Language, like you do, and there it was.  Two references to its use in Scotland dating to the late 19thC citing  Clackmannanshire (Clc.) and Roxburghshire (Rxb.).
