Perhaps the most easily noted detail revealed about the China Roses by the similarity matrix though, was how many accessions had identical SSR profiles. The "C25 grp" on the dendrogram represents the China Rose cultivar Old Blush, with the group's oldest recorded date of introduction into Europe of around 1752 (Cairns (ed.), 2000), and the eight synonyms or sports found in this study: 'Climbing Old Blush', 'Green Rose', 'Single Pink', 'Rouletii' [all ex Antique Rose Emporium], 'Pompon de Paris' [ex Ralph Moore], 'Bengale d'Automne' [ex Vintage Gardens], 'Archduke Charles' [ex ARE], and an R. chinensis var. semperflorens [ex Flower Research Inst., Yunnan]. This large group of synonyms and sports still actively propagated and sold in the trade demonstrates how important 'Old Blush' continues to be, long after being used as a parent of importance in the breeding of modern roses.
....'Rouletii', which is a miniature with double pink recurrent blooms (Cairns (ed.), 2000), appears to be a dwarf sport of 'Old Blush'. 'Pompon de Paris' has also been described as appearing to be identical to at least one source of plants identified as 'Rouletii', and for this accessions sampled in this study, these two cultivars and 'Old Blush' share the same SSR profile. Only one source of 'Rouletii was sampled for this study though, so a future study combining field observation and genetics of multiple sources and their relationship to 'Old Blush' might be of interest to breeders, producers, and growers.

Editor: 'Rouletii' can also be long lived. in 1986 Mrs. Miskelly of Auckland was still growing a 'Rouletii' known to be at least 55 years old.

A single miniature China had been introduced from Canton in around 1800 but was believed to be lost. However, in 1917, it or its descendant was rediscovered growing in pots on a window-sill in Switzerland, and named 'Rouletii' after its finder. Soon it was being used for hybridizing by one or two breeders, notably Pedro Dot in Spain.
