Then, Fred Galle further botched the name's spelling by altering it to 'Miyuno-no-tsuki', borrowing some of the Satsuki cultivar's description instead of the actual plant. All along, it was actually 'Miyo-no-sakae'. Photographs of NA 19876/PI-226144 match those of 'Miyo-no-sakae', as well. NA 73080 arrived at USNA with the faulty Galle version of the name, but is exactly the same plant, and because of its precise misnaming, can be said to trace directly to the original PI-226144 introduction by Creech. -SBL2158670PI 226144
