Shrub; stipulate prickles on flower -bearing branches subulate, usually erect, with ascending mucro (prickles sometimes absent); stipules very thin, scarious, very obtuse; leaflets broader than in R. davurica, pubescent beneath and very often glandular (like R. davurica); bracts of the same
character as stipules, broader than in R. davurica. In all other parts similar to R. davurica Pall. Presumably the eastern race of R. davurica . June— July .

Meadows, shrubby formations and birch forests.— Far East: Kamch., Sakh. Endemic? (in the Aleutians, the most closely related form is R.aleutensis Crep.). Described from Kamchatka (near Petropavlovsk, Tagil River, and between Kharchinsk and Shivelyuch). Type and paratype in Leningrad.
Economic importance. According to Schrenk, in Sakhalin the fruit is stored up for the winter to be used in the preparation of a special kind of food (reminiscent of cereal processed; the thawed-out fruit is ground up and mixed with fish oil.
Note. Hulten (l. c, p.90— 9l) conjectures that the material from which C. A. Meyer established this species may have comprised the hybrid R. davurica X R.rugosa, common in Petropavlovsk. If so, Meyer's view that his species was "inter R.cinnamomeam et R.rugosam media" may indeed be correct.

Rosa amblyotls Meyer
R. amblyotis was distinguished by Meyer in his monograph Cinnamomeae. Erman had collected it in Kamchatka and had reported it under the name of R. camtschatica. According to Meyer, Pallas (Fl. Ross., II, p. 76) had designated it under the name of R. cinnamomea Kamtschatica spontanea ramis glabrous. ...
Before discussing the value of this form, I must say that I saw not only the materials studied by Meyer, but others which are not mentioned in his monograph. Thus, in the herbarium of the Academy of St Petersburg, I have studied samples of R. amblyotis collected on Sachilin Island by F. Schmidt in 1860, and in the herbarium of the Botanical Garden of St. Petersburg, specimens collected in Kamchatka by Peters and Stewart under the name of R. Kamtschatica....
As far as I know, I am inclined to believe that the R. amblyotis is not a distinct type and that this is basically a remarkable variety of R. davurica with more numerous leaflets and more dilated bracts. R. davurica is a rather variable species, and with the materials I had to review, I could have subdivided it into several rather distinct varieties and sub-varieties other than (a) lancifolia and (b) microphylla of Meyer.
