There's an entry in the database for an unregistered daylily (Ruby Stella). The single quotes identify Ruby Stella as an accepted cultivar name but according to the US Patent Office that is a trade name, the actual cultivar name being 'Berrub'. Its USPTO page is here:

I'm not sure how the database usually deals with this, but it would be correctly written without any quotes on the trade name part, the trade name in a different font (not sure how to do that on ATP) and followed by the cultivar name, i.e.
Hemerocallis RUBY STELLA 'Berrub' according to Article 17 of the ICNCP.
EDIT: I figured out that I can submit a proposal to correct this via the entry and have done so. Not sure where to put the USPTO link as verification other than here.
