This is also a synonym of Rosa cymosa Tratt.

Jedmar,
Rosa microcarpa Lindl. = R. cymosa Tratt.

Retzius had a different species in mind. Trattinnick (1823) thought Retzius' microcarpa was a form of R. canina: "b) R. microcarpa Retz, sorte nil nisi canina?"

Did he? I was checking on IOPI and GBIF. In this case needs more Research. Kew, The Plant List and the Encylopedia of Life say it is a synonym of Rosa glabrifolia C. A. Mey. ex Rupr.

Strictly speaking, Trattinnick reported that Sprengel thought R. microcarpa Retz. was akin to canina. Sprengel also (apparently) thought R. laxa Retz. was akin to R. cinnamomeae.

I haven't found Sprengel, yet. I did find Herrmann (1762), if you're interested.

I just found Sprengel (1820), but have not had a chance to read it.

The discussion of R. laxa and R. microcarpa Retz. is on 254-255

I have added the Translation of Sprengel's text, but it doesn't really help. The work of these earlier botanists is very often outdated. We need to look at when and by whom the synonymity of R. microcarpa Retz with R. glabrifolia C.Mey was postulated. That will be probably the latest knowledge.

I usually don't like the gold meets mauve types of russets, but this one looks super cool.

The 'Vintage Book of Roses' says that there are two plants in commerce called 'Duc de Fitzjames', one darker than the other. Mine is lilac pink, similar to the flowers I see in the photos. My plant came from 'La Campanella' in Italy, but I don't know where they got their mother plant. According to Vintage the darker-flowered variety is likelier to be the correct one.

Interesting, thanks for taking the time to sharing this insight with HelpMeFind. Just what HMF is all about - a tool to collect and disseminate gardening information to a participating online community.

La Campanella has many of their Gallicas from Cour de Commer - the collection of François Joyaux. 'Duc de Fitzjames' in commerce is often 'Mme Lauriol de Barny', a Bourbon rose.

I don't have 'Mme. Lauriol de Barny' in the garden and haven't seen it, at least not identified as such. I took a look at the newest page of photos of this variety on HMF, and, though I haven't made a careful comparison, right now I wouldn't swear that the rose I see in the photos isn't my 'Duc de Fitzjames'. My rose is a good tough variety with opulent blooms, coming easily from cuttings, has never reflowered later in the season, and gets some fungal disease after blooming, though not enough to do it any harm. Lanky in growth; thorny. I'm fond of it, mainly because of the very handsome blooms combined with the ability to flourish in quite poor conditions.

Melissa, it would be very helpful if you could post some photos of your 'Duc de Fitzjames' on HMF.

I'm a reluctant photographer (and this isn't the season anyway). I wanted to add to my description that my 'Duc de Fitzjames' sets hips, which are rounded oval, about 2cm wide and slightly longer, and smooth, the orifice not wide, sepals not persistent. They haven't matured yet so I don't know their color. A final note: my rose has long-lived canes, and suckers out, slowly and not aggressively.
