Margaret Furness.  Tea, Noisette and China Mislabels in Australia. 
The rose sold here as Comtesse Riza du Parc is incorrect. HelpMeFind calls it “Comtesse Riza du Parc (in commerce as, in Australia)”. A mouthful; I tend to say “Not Comtesse Riza”.

p58.  The rose known in Australia as the Tea ‘Mme. Charles’ is a large bush with long canes and masses of small-to-medium semi-double flowers in shades of pink, apricot, fawn and white.  It does not match the apricot Tea bred by Damaizin in 1864, which was described by Foster-Melliar in 1902 as “an improved strain of Safrano”.  This imposter is in commerce in Australia and elsewhere as the China ‘Duke of York’, bred by W. Paul in 1894, and overseas it is also sold as ‘Papillon’.

[This rose was sent out from Sangerhausen in the early 1980s to Rumsey Roses, NSW and possibly to world-wide nurseries, under the name Mme Charles]

p92.  "Comtesse Riza du Parc".  The rose in commerce in Australia today as the Tea 'Comtesse Riza du Parc', Schwartz, France, 1876 is almost certainly not the original rose....The rose known as "Comtess Riza du Parc" in Australia has been observed in 2007 under the name 'Madame Charles' in the United States and as 'Dr. Grill' in gardens in France.

Heather Rumsey.  Tea Roses in our Garden.
Comtesse Riza du Parc.  A recent arrival in this garden, but 1876 is not exactly modern.  The main claim this rose has on my attention is that it is a seedling of Duchesse de Brabant.  It has similar globular blooms but is a rosy carmine colour.
