【 摘 要 】

The distribution pattern ofRheumpalmatum,Rheum officinale, andRheumtanguticum, as three Chinese official genuine and endemic species of rhubarb and the monophyletic group in the genusRheum, was analyzed based on the field survey and the herbarium specimens in the present paper.R.palmatumoccupies the widest geographic range, that is Qinling, Daba, Wuling, Dalou, Min, Qilian, Hengduan, the south part of Taihang mountain range and the centre to the east of Qinghai-Tibet Plateau. The distribution ofR.tanguticumis overlapped with that ofR.palmatumin the north-west areas and occupies the higher altitude and the lower longitude areas, whereas the distribution ofR.officinaleis overlapped with that ofR.palmatumin the south-east and occupies the lower altitude and the higher longitude areas. The overlapped betweenR.palmatumandR.tanguticum+R.officinaleand the vicarious betweenR.tanguticumandR.officinaledistribution pattern, combined with the minimum and ambiguous morphological differences and the diversified results on the relationship from the molecular studies of these three species, we considered that these three species might not be good species.
