Hordeum depressum is a distinct, reproductively isolated, tetraploid species. The study of meiosis in hybrids with the closest congeneric relatives revealed intermediate to low pairing with most species. The exceptions are Hordeum brachyantherum ssp. californicum and H. arizonicum. H. depressum , probably share one highly similar genome with ssp. californicum and perhaps two with H. arizonicum . However, it is difficult to draw firm conclusions based only on meiotic figures, since the pairing may be disturbed by high autosyndetic pairing between the H. depressurn genomes.
