Kartesz' 1994 Checklist only includes Rubia tinctoria L. for North America.  Rubia 
brownei, R. peregrina, R. walteri are all now considered Galium hispidulum.  Since your 
authority for R. tinctorum has L. in parentheses, there must be another name as the 
parenthetic L. credits Linneaus for first naming the species, but the author for this 
change must be included.  My guess is that R. tinctorum (L.) is a mistake.
