Bonshiratama Settsu Raikōyen Catalogue, 1938-1939. According to Satomi, 1956, Camellia Varieties of Japan it is a sport of Shiratama and has the synonyms: ‘Kakuba-shiratama’, ‘Seiganji’ and Rōgetsu. However Rōgetsu was listed earlier by Minagawa, 1933, Chinkashū and has priority as the valid name. This name is the local name for Rōgetsu in the Chūbu district. See: Tuyama, 1966, Camellia Cultivars of Japan, pp.88, 90.

Description

» English Description

Minagawa, 1933, Chinkashū: White. Early to mid-season blooming. Belongs to the Shiratama group. Tuyama, 1968, Camellias of Japan, pl.15, p.8, description, p.89: Leaves thick, deep green, roundish-elliptic, broadly ovate, shortly caudate, prominent vena­tion, sharply serrate. Flowers single, pure white, widely opening; petals 5-6, waved and reflexed at the margins, compact stamen column, joined for lower third; anthers yellow. A famous cultivar in the Kansai district of Japan. Very old trees are found around Ikeda City, Ōsaka Prefecture. Described as ‘Kakuba-shiratama’ by Minagawa, 1933; however Rōgetsu is an older name in the Kansai district. ‘Rō’ = waxing and ‘getsu’ = month, in this case December of the lunar calender, alluding to the early flowering of this cultivar. For colour photos & descriptions see: Tuyama, 1966, Camellia Cultivars of Japan, pl.49, p.90 & p.303; Encyclopedia of Camellias in Colour, vol.I, 1972, pl.82, p.63; Seibundō Shinkōsha, 1980, Senchinshū, pp.163, 257; Andoh, 1971, Tsubaki, Meika no Shōkai to Saibai, pl.33, p.12 as ‘Rohgetsu’. Yokoyama & Kirino, 1989, Nihon no Chinka, pp.48, 49. Synonyms: ‘Bonshiratama’ in the Chūbu area and ‘Shi­rorōgetsu’, ‘Kakuba-shiratama’. Parent of: Shibori-rōgetsu, Aka-rōgetsu. SCCS., Camellia Nomenclature gives ‘Oborozuki’ and ‘Seiganji’ as synonyms. While ‘Oborozuki’ is a different reading of the characters for Rōgetsu, the first character ‘Rō’ = ‘oboro’ is different and trans­lates as ‘hazy’. Oborozuki means ‘Hazy Moon’ and is actually a different cultivar to Rōgetsu; both being listed separately by Satomi, 1956. It is also the name of an ancient variety listed in Sakuden’s Hyakuchinshū, 1630. Seiganji is also a different cultivar being a white with red spots, double camellia listed by Mizuno, 1681, Kadan Kōmoku. Corruption of the name: ‘Roget’s White’. Different reading: ‘Rohgetsu’, ‘Rowgetsu’.
