Naming caution

The discussion re: "Arisaema du-bois-reymondiae" scares me a lot.  One of
the motivations behind establishing the Australian Areae Collection was the
problems encountered in the Nursery Trade in Australia.  Mis nomenclature.
It is a worldwide
problem.  No better example exists than Madan Tamang!

I strongly believe that all discussion involving material from Kaichen
should include the NUMBER that it was bought under rather than a name.  Once
material can be positively identified then we should use the name that we
KNOW is correct.  Chen Yi admitted that they need help to identify the
species that they are selling.  Everyone on the group should understand the
difficulties associated with trying to achieve correct nomenclature for our
favourite plants.  Our experience is showing that the photographs supplied
Kaichen are not necessarily lining up with the material when it flowers.  We
have just had A4 flower and are so pleased that we now have the true
Arisaema candidissimum in cultivation in Australia.  It is nothing like the
picture supplied by Kaichen (or for that matter the description that Chen Yi
gave me when I was selecting tubers).

What concerns me most is material getting into the "trade" with the wrong
names.  We have already seen nurseries in the USA offering material under
Kaichen's names then saying that they are probably not correct.  Once seed
of this material gets onto the AEG distribution I hope it will not be a case
of making the problem worse.  One thing we should be guilty of is "doing it
