I have only just obtained this plant from Bob Brown at Cotswold Garden Flowersas A.zongbayena. In the Online
Flora of China it is listed as Aspidistra zongbayi, but I assume they are the same thing.
I haven't yet had time to check that it matches the description.
It hasn't really established in the pot, but it has produced a flower, which seemed worth recording for later reference.
I finally settled down to checking it's identity, and find that it agrees with the description in the Online Flora of China in all respects, save for having eight corolla lobes and eight stamens instead of the six recorded.
This year it has produced flowers with six corolla lobes, which is reassuring.
