Cytogenetic Studies in Rumex

“…As the studies of the Scandinavian species and hybrids of this subgenus must be taken as preliminary experiments, only the chromosome numbers and some other minor observations will be reported here. JENSEN, 1936;KIHARA and ONO, 1926). The number given here for R. domesticus was also found by KIHARA and ONO in material from Copenhagen, but in their material from Japan the octoploid number 2n = 80 was found.…”

“…200. All the species, except the last-mentioned one, have been studied previously by other workers ( JARETZKY, 1928;JENSEN, 1936;KIHARA and ONO, 1926). The number given here for R. domesticus was also found by KIHARA and ONO in material from Copenhagen, but in their material from Japan the octoploid number 2n = 80 was found.…”

“…The foregoing events in R. Acetosa bear certain similarities to conditions found in the hybrids between species of the Lapathum section of the genus Rumex, Jensen (6). One may question the legitimacy of comparing phenomena in one species with those in another..., yet, there are grounds for such an action.…”
