On Cinnamon Roses, especially on its species which grow wild in Russia. A contribution to the Flora of Russia. From C. A. Meyer. (Extract) (Read 15 May 1846.)
...I have limited my special investigations to the true Cinnamon-Roses, which I bring here in four sections.
I. Smooth branches. The blooming stems with its branches is not armed, or veyr rarely with a solitary bristle-shaped prickle.
1. R. alpina L., with which I unite R. pyreanaica and lagenaria.
2. R. blanda Att. I cannot consider R. fraxinifolia Borkh. as distinct.
3. R. macrophylla Lindl. Rosar. monogr. t. 6. The rose pictuted with the same name in Wallich's Plant. asiat. II. t. 117. seems to be very different tahn this.
II. Smooth branches, which as the branches, are armed with bristly or awwl-shaped prickles. No other-shaped stipulary prickles at the base of the stipules.
4. R. stricta Donn.
5. R. acicularis Lindl. To here R. alpina Pall. , baicalensis Turcz., gmelini Bge, carelica Fries.
III. Smooth branches, which either have stipulary prickles, or are armed also with other, differently shaped scattered prickles.
6. R. Woodsii Lindl.
7. R. californica Cham., Schlechtd.
8. R. laxa Retz. with a variety β R. songarica Bge.
9. R. cinnamomea L. A species with numerous varieties in Russia, to which belong R. mutica and fluvialis Fl. dan., R. majalis, R. cinerea and turbinella Sw., R. mosquensis Spr., R. gorenkensis Bess., R. glabrifolia m, daurica Pall., Willdenowii Spr. and microcarpa Retz.
10. R. amblyotis m. A good species from Kamchatka, which is often confused with R. kamtschatica and r. cinnamomea.
IV. Densely woolly, hirsute branches.
11. R. rugosa Thb. Under this I group as special varieties R. ferox Lindl., R. kamtschatica Lindl., Vent. and Cham.
R. taurica MB., mollis Ledeb.Gebleriana Schrenk are not to be counted among Cinnamon Roses.
