V. Typus R. Wahlenbergii, 21: a precedente his notis distincta: foliolorum acumine mediocri, foliolis folii a angustis subpræcisis marginibus rotundatis sine angulo; serratura minus profunda acutaque; aculei breviores validi proni, dorso typice subrecto.

64. R. (Gall, gl.) suionum At. n. spec: in Suecia media antiquitus culta cum R. francofurtana, corolla simplici alba, foliolorum forma et serratura omnino typi; hybriditatem vetant chromosomata ceteraque omnia.

Translation:
V. Type R. Wahlenbergii, 21: differing from the preceding by the following characters: sharpness of the leaves is moderate, the narrow cut on the rounded margins of the leaflets is without an angle, the serration is less deeply acute, prickles are shorter and stronger, typically erect on the back.
64. R. suionum AT, new species: in central Sweden together with R. francofurtana since antiquity, corolla white single, forrm and serration of the foliage as for the type, in hybridisation preventing chromosomes of all others.
