question about Hordeum species
Hi, I have a question about the classification of Hordeum genus. Some publications indicated that the Hordeum comprises about 33 species (Blattner, F.R. 2009, Breeding Sci 59:471–480.), but I can see 39 Hordeum species from Wikipedia. I wonder how did you define the new species and which article we can cite for this number? Dongying2021 (talk) 16:39, 12 February 2023 (UTC)
