It's a registry about seed or it's a registry about tree ?
it seems 2 Jch exist, the other one is "Jungle chapter", a seed registry.
in both case, it seem to me a good idea to move ref from description to ref:* namespace to allow better use.
for seed, I create ref:seed on the wiki, feel free to review/improve and/or help to document your ref if it's not the same as the previous one
