Polygonatum bulbosum?

Polygonatum bulbosum is currently placed under synonymy with cirrhifolium, but I have seen the types, dissected flowers, and grown them in the garden. They are different!! I am just waiting to get more DNA work done to show how different they are. Also, P. bulbosum has blue fruits and cirrhifolium red fruits, the rhizomes are different, the peduncles of the inflorescence are triangular and scabrous whereas cirrhifolium are round and smooth, and bracts of the inflorescence are different! 

 Acceptance in FOC is not a good requirement since it is an English translation for the most part of the older Chinese publication -- only recent volumes have newer taxonomic changes. Other than that most databases are based on Jeffreys work in 1979 and even some of those ignore his nomenclature which I find he was mostly right even if a few species are in the wrong genus. 

 Cedric finally believed me this spring about the white hookeri he photographed being the newly described P. qinghaiense.

Aaron , I have already received a reply from Cedric Basset about the identification.
He says that bulbosum is an invalid synonym of cirrhifolium and is not accepted by "flora of China, GRIN, etc..."
What do you think ?

Its appropriate name is an old name, but it is currently lumped in with cirrhifolium. Its native range is SW-SC Sichuan and N-NE Yunnan. So far, I've never seen it outside that area, but it should be expect in neighboring Guizhou. Like many of Leveille's Polygonatum he named it twice, first bulbosum and then lebrunii, both from Yunnan and both collected by E.E. Maire. Polygonatum bulbosum shoudl be the correct name for this.
