The name of cultivar is quite unique and included inspiration of the developer.
This cultiver is toku daruma royal tama-botan, retusus v major with very lage roud tubercles.
I have no idea why the word of "Royal"added on the name.
Since tubercle size is only possible to confirm by own-root, I keep quite many seedlings.
The photo is one of my seedlings, sown seeds on 12th November 2006.
The current plant diameter is around 10 cm.
Seeds were collected from my grafted plants.
