Hi, I happened to be looking at Marguerite Desrayaux listing and noticed that you list it as 9-16 petals, but the picture looks to be of a double bloom. Here's a link to Rogers Roses with a picture of MD and it is listed as a double. Thought maybe your info on the hmf listing was incorrect, so I thought I'd ask. Thanks for all of your work!
The original description in the "Journal des Roses" of 1905 clearly says "demi-pleine" (semi-double). This would indicate that the rose we know today as 'Marguerite Desrayaux" is probably mislabeled.
Hi Jedmar I tend to agree with you that this rose is misappropriated, but for clarity demi-plein is half full rather than semi double, most of Nabonnand's breedings were described like this
