431	PI 226144	'Miyo-no-sakae'	Rhododendron hybr.		NA	Not Available	1955							Cultivar	From the record of NA 73080 at the U.S. National Arboretum (material received from Steele's Nursery in 2003: This was originally brought to the U.S. by John Creech under PI-226144 (see NA 19876) as 'Miyuno-sake'/'Myuno-sake' in 1955; in 1984, the name was updated by Barry Yinger to 'Miyo-no-tsuki', but his assumptions about the Romanization were incorrect, and he confused it with a Satsuki cultivar of the same name. 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. -SBL	2158670	PI 226144
