Japan; seed presented 1959 by Gov't. Forest Exp. Sta., Okidate, 

 Aomori, Japan. H. Fisher, Amer. Hort. Mag. 49(4):318. 1970 - lists 

 many more PI collections of this taxon from the wild in Japan, some of 

 which were named subsp. radicans, or var. radicans. Considerable 

 controversy exists regarding which infraspecific name, var. paludosa or 

 var. radicans, is correct for this taxon. At the botanical rank of varietas, 

 the combination /. crenata var. radicans was not validly published until 

 1953 by Ohwi (Flora Japan, 1st ed., in Japanese). The varietal rank, var. 

 paludosa, was validly published 9 years earlier by Nakai (Jour Jap. Bot. 

 20:189. 1944) but as /. radicans var. paludosa instead of/, crenata var. 

 paludosa. In accordance with the International Code of Botanical 

 Nomenclature, the earliest validly published epithet at the botanical 

 rank must be regarded as the correct name; therefore, the current correct 

 name for this taxon is /. crenata var. paludosa (Nakai) Hara. It is 

 interesting to note that Ohwi (1953) called the taxon /. crenata var. 

 radicans without citing the basionym (/. radicans Nakai ex Hara, Bot. 

 Mag. Tokyo 50:187. 1935). However, in the corrections and additions 

 to his Flora (Bull. Sci. Mus. Tokyo 33:78. 1953), Ohwi correctly made 

 the validating combination of var. radicans by including the basionym 

 /. radicans Nakai ex Hara. The English edition of Ohwi's Flora of 

 Japan, p. 600. 1965, followed Hara (1954) and accepted var. paludosa 

 and cited /. crenata subsp. radicans, I. crenata var. radicans, 

 I. radicans, and /. radicans var. paludosa as syns. of /. crenata var. 

 paludosa. The name /. crenata var. paludosa refers to biologically 

 highly variable populations that are found occurring in the wild and 

 differ from var. crenata, the type variety of /. crenata, in a number of 

 correlated characters. Therefore the name paludosa can never be 

 legitimately applied as a cultivar epithet. = PALUDOSA of Krussmann 

 (but not PALUDOSA of Clarendon), RADICANS, /. radicans var.

PALUDOSA (Clarendon Gdns. Nurs., Pinehurst, North Carolina, cat. 

 p. 1 1. 1962) - lvs. variegated; narrow, 1" long; very new; seed from 

 Japan. It is known that Clarendon was a recipient of USDA plant 

 introductions of var. paludosa. The Clarendon plant probably is a 

 seedling from this source and may be an authentic clonal selection. 

 Illegitimate as a cultivar name, since it is in Latin form. If the leaf 

 variegation of this plant is stable in the future, the plant could be given a 

 new, legitimate name, and internationally registered. 



PALUDOSA (G. Krussmann, Handb. Laub., 1st ed., Fascicle Pub., 2:23. 

 Dec. 1960, as a cultivar name) - low growing; lvs. broadly elliptic, apex 

 round, base obtuse; occurs in swampy locations; orig. Japan; probably 

 not yet introd. Idem, Handb. Laub., 2d ed., 2:183. 1977 - correctly 

 recognized var. paludosa (Nakai) Hara at botanical rank, and not as a 

 cultivar. D. Huttleston, Plants Growing in Conservatories and Gardens,
