Comment: Rosa pendulina is another species in the large and taxonomically difficult genus Rosa, which is relatively easy to determine. Most apparent traits, which distinguish it from numerous other roses flowering in reddish shades are its deep pink-purple flowers without whitish center and long, undivided calyx leaves. It has dense, strait, thin and relatively soft thorns on stems (see picture 4) and older branches, while young sprouts are almost glabrous have no hairs or thorns. When the plants are in fruit they carry characteristically nodding, narrow and +/- flask-shaped hips with persistent, long and strait, remnants of calyx. Another conspicuous character of this species is underground runners (stolons), so, quite often one can find several stems in a relatively small area growing together. The plant on these picture seems young and still small, yet there were almost ten small, still younger stems growing in a distance of less than 2 m from the main plant.The species is distributed in central and south Europe and is quite common there. In Slovenia it is most common in alpine and Dinaric phytogeographical region and in montane and subalpine elevations sometimes climbing up to almost alpine elevations. Ref.:(1) M.A. Fischer, W.
