Rodger Whitlock was musing on his clones of Pinellia cordata, and trying to work out which was which. As I said, I have not seen "Don Jacobs' Form" but I wouldn't be surprised if the majority of stocks with well-marked leaves turned out to be 'Yamazaki'. The species is normally supposed to have dull, less-well marked leaves (presumably this is what Diane Whitehead received from China), so I don't think that Rodger's view that: > "Don Jacob's Form" = the usual form, the type< is correct. As usual we are straying into muddy waters to assert that any one variant is the 'type', but if duller leaves are the norm then "Don Jacobs' Form" is at least distinct from them, if not from 'Yamazaki'.
