Rudolf Kamelin (pers. comm.) believes that Polygonatum verticillatum is absent from China, and that the plants there are instead P. kansuense ( P. erythrocarpum). In SW Asia and Europe, P. verticillatum has leaves in whorls of 5--7, inflorescences mostly 3- or 4-flowered, perianth white, and berries dark blue-green (although one of us (Tamura) has collected P. verticillatum with orange berries in S Denmark: Tamura & Kubitzki 3425 (KYO)). Tamura considers that P. verticillatum of the present sense may be a species in which different lineages are lumped. However, Chen and Tamura together decided to maintain the present circumscription until sufficient morphological variation data have accumulated. Kamelin also notes that Polygonatum minutiflorum, regarded here as a synonym of P. verticillatum may instead be synonymous with P. gracile in which case the former name, published in 1915, would have priority.
