Kew plant list says:
Fortunatia biflora (Ruiz & Pav.) J.F.Macbr. is a synonym of
Oziroe biflora (Ruiz & Pav.) Speta
I am grateful to a friend who contacted me to say: " I believe it is
a synonym for Fortunatia biflora and looks very much like images of that
species I have from Kew. There are images on the web on chileflora, and
also one on flickr which I am not convinced is correct."
Thank you, Jon, this is indeed helpful
