Dear peoples,
 
I have received a few Arisaemas from Tony Avent a while ago, apparently =all from China. One has a spathe quite similar to that of Ar. =sikokianum, although hooded and partly pendulous. Of course it isn't Ar. =sikokianum (no swollen appendix top). It was given as sikokianum though. =Using the provisional key of the Flora of China by Li Heng (unpublished) =I arrive at Ar. bockii. This species may indeed be purple, although also =green (as it happens, I do have a green one flowering right now too, =which was given to me as Ar. du-bois-reymondii........). Murata's =provisional list of Chinese species (unpublished too), lists Ar. bockii =and has in its synonymy "A. sazensoo auct. in China", meaning "what =authors have called Ar. sazensoo in China". This again underlines the =possibility of purple spathes in bockii, as sazensoo is purple. 
 
Both Murata and Li Heng do not list Ar. sazensoo for the flora of China. =Contrary to this, Guy Gusman in his "Japanese Arisaemas" (Bull. Alp. =Gard. Soc. 65 - 1997) claims that Ar. sazensoo does occur in China =("continental Eastern China"). Following Murata, may we assume that Guy =actually means purple forms of Ar. bockii (as in my plant) and mistook =them for Ar. sazensoo? Guy, what's your latest opinion, hearing this? Or =did you already know this? 
 
Sazensically yours
Wilbock
