Rosa tomentella Léman ex H. Christ. Stumpfblättrige Rose. To 3 m. Upright, more or less stocky habit. Prickles hook-like, similar. 5-7 leaflets, dark green, glossy, broadly ovoid to roundish, rounded at the base, some few wedge-shaped, beneath pubescent and glandular on the nerves, often also on the surface, doubly or more glandular serrated. Sepals foliaceous. Petals white to light pink, small sepals relexed after blooming, fall off. Style channel narrower than 1 mm. Stigma head globular, bouquet-like. Pedicel seems as long as the fruit, usually without glands.
The above described race is, especially in northern Germany, replaced by a race with narrower ovoid and more strongly acuminate foliage, which could be accepted as an independent species Rosa sclerophylla Scheutz [IOPI: synonym of R. obtusifolia].

Medium-sized shrub (ca. 1 m), resembling R. canina L. and even more so R. corymibifera Borkh., with its abundant, usually large, equal, flattened falcate or hamate prickles and small, orbicular, typically more or less pubescent, glandular-serrate leaflets; petioles always pubescent and glandular. Flowers on long, generally smooth pedicels; sepals pinnate, with numerous short and typically broad glandular -dentate pinnules, recurved, caducous; petals large (2—3 cm long), varying in color from
whitish to bright pink; style heads columnar, slightly pubescent. May— June.
Shrubby formations, rocky places.— European part: M. Dnp., V. -Don, BL, L.Don, Crim.; Caucasus: Dag., W., E. and S. Transc, Tal. Gen. distr.: Centr., S. and Atl. Eur., in the north to S. Scandinavia; Turkey, Artvin District (Grossh.). Described from the Ukraine. Type in Kiev.
Note. R.klukii (as understood by D. I. Litvinov) is similar to R. corymbifera and others, and certainly represents an entire group of basic forms, artificially united because of similar pubescence of leaves.
The following species [R. leucantha] appears to represent one of these.
