R. onoei var. oligantha (Fig.1. j. faint, refreshing 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.

R. onoei Makino var. oligantha (Franch. et Sav.) H. Ohba (syn. =R. luciae Franch. et Rochebr.)
J. Jap. Bot. 75:157 (2000)
Distribution: Downs and lower mountainous in Honshu (Miyagi Prefecture and further south, and Toyokawa, Aichi Prefecture and further east)
As the Japanese name "Yama-Teriha-No-Ibara" indicates, it has glossy leaves and is often confused with "Teriha-No-Ibara" (R. luciae). However, its leaflets are not as round as those of R. luciae. The tree shape also differs. Unlike R. luciae, which spreads sideways hugging the ground, this rose grows upwards, sometimes climbing up trees using its prickles, 2 to 3 metres tall, and sometimes hangs down a steep slope. While the number of leaflets is 7 to 9 for R. multiflora and R. luciae, 5 to 7 is normal for all the R. onoei varieties, including var. oligantha. The flowers are white, 2 to 2.5 cm across, and closely resemble those of R. multiflora. However, this rose has thick hairs on its styles, while R. multiflora has none.
