I suppose that (theoretically) it would even be possible that 
Triticum borealis might be correct, as borealis might be a noun, see
If Triticum boreale and Triticum borealis are both correct spellings
(of heterotypic names), they would have to be treated as homonyms. 
If in both cases the epithet is an adjective, both names would have 
Triticum boreale as the correct spelling and would be homonyms.

No, this is dealt with in Rec. 23A.2, while the original poster refers
particularly to Rec. 23A.3(g), which deals with cases like below.

Such cases should be submitted for formal evaluation (Art. 53.5),
and are due to be listed in a new Appendix.
