Notes:
Rosa x damascena Mill. Gard. dict. ed. 8. Rose no.15: 1768.
Recent research in Japan indicates that both summer and autumn damask roses originated with (R. gallica X R. moschata) X R. fedtschenkoana. Gene, Vol. 259, Issues 1-2, 23 December 2000, Pages 53-59.
Rosa belgica Mill. is today seen by botanists as a synonym of Rosa x damascena Mill. However, the descriptions of Miller are quite different re habit, number of leaflets, fragrance, sepals, bloom form. It is probable Belgica was actually a hybrid damask. Modern Roses says it was a alba-canina hybrid.
