R. nipponensis (Fig.1. c. slight fruity scent).....
....the fragrances which the nine roses below give off were not so intense. They lacked highly fragrant components, and the amounts of the volatiles these roses emit were low: R. acicularis, R. nipponensis, R. fujisanensis, R. onoei var. hakonensis, R. onoei var. oligantha, R. paniculigera, R. luciae, R. luciae f. glandulifera and R. hirtula.

Takane-Bara (High Mountain Rose) R. nipponensis Crép. (syn. =R. acicularis Lindl. var. nipponensis Crép.)
Bull. Soc. Roy. Bot. Belgique 14:7 (1875)
Distribution: Honshu, Shikoku
'Nippon' means 'Japan' in Japanese, and R. nipponensis is an endemic species, which is seen in high mountains in central areas of Honshu and in Shikoku, usually on forest margins or in craggy places in conifer zones and Dwarf Siberian Pine (Pinus pumila) zones. This rose closely resembles R. acicularis, but it is smaller in size, and the leaf is totally different. The leaf of this rose has 7 to 9 leaflets, while that of R. acicularis has 5 to 7. Its lateral leaflets are roundish while those of R. acicularis are oblong. Also the margin of its leaflets is finely toothed unlike that of R. acicularis, which is crenated.
The flower is 3 to 4 cm across, and looks more delicate than that of R. acicularis....

Rosa acicularis nipponensis: Rose sauvage, rose intense. Japon, 1894. Buisson dense d’environ 1m de hauteur, il couvre son jeune bois d’aiguillons ténus, plus épars sur le bois âgé, vert sombre. De petites fleurs, rose vif, étoilent en fin de printemps son feuillage vert mat aux folioles éliptiques, à dents de scie. Ecloses en solitaires, elles sont suivies de fruits en petites poires rondes, rouge vif à maturité. Cette sous-espèce asiatique très rustique a plus d’intérêt au jardin, que son homologue d’Europe et d’Amérique du Nord, Rosa acicularis.

R. acicularis var. nipponensis (Crép.) Koehne R. nipponensis Crép.
Leaflets seven or nine, sometimes 11 on sterile shoots, elliptic, mostly rounded, not much over 1 in long, finely toothed. Flowers in the introduced plants a beautiful deep purplish red.
This variety was, with hesitation, separated from R. acicularis by Crépin, whose description is based on specimens collected in Japan on Mt. Fuji by Tschonski and on...plants grown in the Copenhagen Botanic Garden...[which] had been raised from seeds received from St Petersburg. Typical R. acicularis also occurs in Japan.
