The Chinese plants identified in FRPS as the NW Himalayan Saxifraga meeboldii Engler & Irmscher evidently belong to S. decora. The description in FRPS states that the petals are "pink or purple," but in true S. meeboldii they are yellow. It appears that the description applies to one or both of the synonyms that were listed under S. meeboldii, namely S. decora and S. lamarum. Although most of the characters distinguishing the latter two taxa are encompassed by the description in FRPS, the glandular hairy sepal surface clearly points to S. decora (S. lamarum has sepals abaxially glabrous). Therefore, the present authors have provisionally taken S. decora to be the species intended in FRPS under S. meeboldii. It remains to be seen whether S. lamarum is synonymous.
