zuzu said:It's true that the "var. autonyms" are being phased out in most cases, and this probably will happen with H. fulva var. fulva in the near future. When it does, we'll make the appropiate changes. ITIS is a reliable source in most cases, but the dates of information have to be considered. The latest information cited on the ITIS page dates back to 2010. The CoL updates much more frequently and cites a 2014 source on its H. fulva var. fulva page.
The reference seems to be the WCSP of September 2014 but I can't get that database to work right now, it gives me an error every time. I did find this on The Plant List, which again gives H. fulva as the accepted name:

based on WCSP 2012. I wonder what changed between 2012 and 2014?
I can understand all the variations of H. fulva being included under that name. However, H. flava (correctly lilioasphodelus now), listed as a synonym for fulva var. fulva in the Catalogue of Life, isn't a H. fulva based on this DNA AFLP research: Tomkins, J. P., Wood, T. C., Barnes, L. S., Westman, A., & Wing, R. A. (2001). Evaluation of genetic variation in the daylily (Hemerocallis spp.) using AFLP markers. Theoretical and Applied Genetics, 102(4), 489-496.
"Utilizing neighbor-joining analysis, the six H. fulvas were distinctly separated from the other species. Clustering within the fulvas also supported some fine-scale taxonomic classifications. For example, the distinction described by Erhardt between the two fulva double-flowered genotypes ‘Kwanso’ and ‘Flore Pleno’ is reflected in the molecular data. .............. Erhardt had proposed a close relationship between two other members of the citrina group, Hemerocallis lilioasphodelus and Hemerocallis thunbergii, which was well supported by our data, but they did not closely group with the other citrina members. In fact, our data suggest that the middendorffii group and the citrina
group should be merged into one large taxonomic group."
(FWIW the six fulvas tested were var. sempervirens, 'Kwanso', 'Flore Pleno', var. rosea, 'Europa' and var. maculata).
