P. S. The Hoyan 14(1), dated 1 February 2014, publishes David O. Gray’s letter of 19 January 2012 alongside Christine M. Burton’s comments. Gray recalls Grace Arndt’s named plants, which he saw mature in 1974, and describes Snowball’s large leaves and large, nearly spherical flower clusters. His account is retrospective; the original naming publication and pollen parent are not supplied.

On physical PDF page 5, Gray also recalls Little Star as a smaller carnosa-like plant with long, very dark leaves and light pink flowers. He associates it with Arndt’s seedlings and says he lost his own plant. This account neither establishes a first naming date nor resolves the different McDonald attribution reported by Burton in 2006. The suspected parentage and possible seed irradiation remain retrospective recollections.

Burton contrasts the account with plants she had received under that name, then acknowledges that she may never have seen the true cultivar. This qualification matters when reading her earlier pink-flower description. The letter’s uncertain radiation recollection does not establish a documented treatment or authenticated hybrid cross.
