Hi Greg;
interesting questions
it's me and my semps-friends in germany who starts to collect all informations about every named semps all over the world; the actual result you can find in our dictionary/homepage;
we find out that there is no official institution who cares about it;
any hobby-semps-breeder may give his seedlings names....
but then you will have thousands of cultivars with different appearence but the same names;
so we start to check every new upcoming cultivar-name and find out if there is a serious source/breeder behind it; only if you can compare your new seedlings with a great stock of collected named cultivars it is serious to give names to it....that is what we think;
if we can't find the origin and the appearance is common we won't add it to our database because there are enough known cultivars with the same appearance;
when a "normal" semps-collecteur starts breeding and there is a very nice one he wants to name.....then a stage like this on ATP or our forum might be the right place to show it....after some years of observance and own comparison;
then a lot of experienced semps-fans may discuss to name it or not;
