About the chek list for genus Gymnocalycium, the excellent one is on the
home page made by Mr.Ulrich Creutzburg (Germany).
For the convenient of the viewer, if you click here, you can go directly
the check list in his home page.
The genus Gymnocalycium has beautiful flowers and its figure shows a lot
of variations. Many people in the world are fascinated by this genus.
Also in Japan, over 25 years ago, the boom for this genus was occurred.
At that time, many new species (plants collected in the wild or seeds)
were imported in Japan. Unfortunately,many of these new species were reported
and named by amateurs and collectors without precise scientific examination.
Therefore many of these names are pointed out to be illegal from the viewpoint
of classification recently.
The possibility that some species were introduced by the error name when
they were imported couldn't be denied. In addition to these facts Japanese
have a custom to give special Japanese name to each species. So many species
are sold and known by two different names. This custom increased the complexity
and confused the understanding for species in Japan. Recently, we can easily
look the photographs of the genus Gymnocalycium in the foreign collector's
and investigator's home page by the Internet. Then we will find that some
differences between species with same name exist. Although, there could
be some diversity between typical one and others and also plants grown
from seed sometime shows wide diversity. I hope the understanding for the
genus Gymnocalycium become same in Japan and in foreign countries. So I
want to exchange the information about this genus. In my home page, I will
show photographs of my collections,which are listed by the name when I
got the species.
