Stout considered some of the species specimens to be clones of an individual from a species. Thus they have cultivar names so we write
Hemerocallis fulva 'Europa' as a cultivar name. Kwanzo wouldn't be a synonym for
H. fulva var.
fulva, I don't think. I'll have to check some references but I think
H.f. var.
fulva indicates a single-flowered diploid, whereas kwanzo is a double-flowered triploid. Kwanzo is written either as a varietas or a cultivar, i.e.
Hemerocallis fulva var.
kwanzo or
Hemerocallis fulva 'Kwanso' (I'm interchanging z and s because it is spelled either way) depending which reference one goes by. I believe Stout wrote it as a cultivar name, i.e. the latter, but the nomenclature wasn't as organized then as it is now. Presumably it wouldn't be a species/varietas since it is sterile (has no normal female parts) if one defines species and varietas as something that comes reasonably true from seed in nature.
Since there are different treatments of the daylily species, for ATP I'd be inclined to go with Dr. Plodeck's list for the database (which means adding quite a few!):
http://www.hemerocallis-specie...
The AHS database/register includes some species names because the original Descriptive catalog of Hemerocallis clones, 1893-1948 prior to the AHS listed all the known daylilies at the time, and that would have included species.
One other thing I noticed in the ATP database is that there is an entry for
Hemerocallis fulva as the "Ditch Lily" and
Hemerocallis fulva 'Europa' separately. The "Ditch Lily" is actually the triploid 'Europa' rather than the diploid species
H. fulva.
Not sure if I'm adequately answering the question. I can do some more research in a couple of days if not.
