I did a search for 'citrina' in the database here and there are two results with Baroni in 1897. The cultivar shows Baroni as the hybridizer and h. citrina shows Baroni as "discovered by". The cultivar 'Citrina' does not have any pictures, but the species h. citrina does. The information about these two is also similar.
Daylily (Hemerocallis citrina)
However, in the AHS database there is only one listed. 'Citrina' (Baroni, 1897), so I am confused. Does the AHS database not list species daylilies?

The other thing I am wondering is if they could possibly be the same. Just throwing this question out: Why would Baronia register a cultivar with the same name as the species if they are different? And why would they both have the same year?
If someone could explain the difference between these two (if they are different) I would appreciate it. I received h. citrina in a trade. I don't have any pictures to share of it yet. Since it is a nocturnal (and the only one that I think I have), I am hoping to post a picture of it this year.
