p. 68: ...identical phenotypes were found within OGR cultivars for R. xcentifolia L. 'Rubra' and 'Crested Moss' for 'Kazanlik', 'Quatre Saisons Blanc Mousseux' and 'York and Lancaster', and for 'Old Blush' and 'Viridiflora'.

p. 71: ʻQuatre Saison Blanc Mousseauxʼ, ʻKazanlikʼ, and ʻYork and Lancasterʼ are clustered as a single allelic phenotype, in agreement with Iwata et al. (2000). The first cultivar is a known sport of ʻQuatre Saisonʼ (selected by M. Laffay prior to 1837) and belongs to the Moss group (Beales et al., 1998; Cairns, 2000; Harkness, 1978); ʻKazanlikʼ and ʻYork and Lancasterʼ are two accessions of unknown origin morphologically similar to ʻQuatre Saisonʼ with deep pink and pink blended fl owers, respectively.

York and Lancaster ('À Pétales Variés', 'Damascena Petala Variegata', 'Folio Variegata', 'Versicolor') Damask. Monardes pre-1551. [The author cites information from many sources...] named in 1551 in memory of the end of the bloody English 'War of the Roses'... This variety has been known for quite a long time; but it is not much thought of except as a collector's item; its sub-variety, 'La Félicité', is preferred... Going by its look, this flower takes its origin from the white 'Tous-Mois' [Damask Perpetual] on which some pollen from a red rose [Gallica] has fallen... One of the great romances, immortalized by Shakespeare in 'Henry VI', was connected with a conflict lasting thirty years and [is known] in history as the 'War of the Roses'. Two branches of the royal family of England, the House of York and the House of Lancaster, both descended from a common ancestor, Edward III, claimed the right to the throne... The House of York had for a rallying sign a white Rose while the Lancastrians selected a rose Rose... in 1486, both houses were united by the marriage of Henry VII of Lancaster with Elizabeth of York...
