|discussion=<p>The name <i>Prunus</i> serrulata has been widely applied to <i>P. speciosa</i> by North American botanists and horticulturalists (for example, P. G. Russell 1934; A. J. Rehder 1940); some Japanese cherry experts now circumscribe <i>P. serrulata</i> more narrowly so that it includes only the white-petaled, double-flowered cultivars closely resembling the nomenclatural type. The single-flowered plants that are found escaping rarely and perhaps naturalizing in the flora area have been called P. lannesiana (Carrière) E. H. Wilson forma albida (Makino) E. H. Wilson or <i>P. speciosa</i>. Based on principal components analysis of 35 morphological characters from 468 individuals of the <i>P. serrulata</i> complex and related taxa, K. S. Chang et al. (2007) argued that forma albida is distinctive and separated from other taxa of the <i>P. serrulata</i> complex. H. Ohba (2001) recognized it at species rank as Cerasus speciosa (Koidzumi) H. Ohba. The classification and nomenclature of Japanese flowering cherries are complex, convoluted, and subject to varying interpretations, and no attempt is made to resolve them here. Centuries of selection and hybridization have blurred species distinctions, and it may be best to do as horticulturalists have and forsake botanical species names in favor of traditional and cultivar names. Whatever the name, these Japanese flowering cherries are widely grown as ornamentals where winters are not too cold nor summers too hot; they escape only rarely and have been found naturalizing only near planted specimens.</p>
