Vepres intricato-ramosus, sempervirens, eglandulosus, in apertis 1,0 — 1,5 m altus, in silvis et 

 dumetis excelsius scandens. Turiones perennes, robusti, arcuati, demum procumbentes, autumno 

 ramosi apicibus radicantibus, acutanguli, sulcati, pruinosi, inferne patenter pilosi, superne pube stellulata 

 sericeo-micantes, aculeis validis conformibus e basi dilatata lanceolatis, in caule primario rectis, in ramis 

 vero deflexis vel falcatis armati; folia ternata vel saepius pedato- vel digitato-quinata, hieme longe vel 

 omnino persistentia; petioli supra plani, aculeis aduncis armati; stipulae lineares; foliola omnia petiolu- 

 lata, coriacea, argute et apicem versus duplicato-serrata, supra obscure viridia, glabra vel rarius pilis 

 singulis instructa, subtus tomento denso adpresso alba; terminale variabile, saepissime obovatum, 

 cuspidatum, ad basin angustam truncatum. Inflorescentiae elongatae angustae tliyrsoideae vel pyra- 

 midalis inferne foliiferae ramuli inferiores erecto-patentes, racemosi, intermedii breves, patentes, cymoso- 

 partiti, omnes cum rliachi appresse albo-tomentosi, aculeis validis saepe crebris falcatis vel uncinatis 

 armali. Flores mediocrcs, spectabiles; sepala albo-tomentosa, in flore et fructu reflexa; petala obovata 

 vel suborbicularia, demum patentia, saepissime laele rosea, inlerdum pallidiora; stamina externa internis 

 vix longiora, stylos fere aequantia, post anthesin fructui applicata; pollinis granula parva, conformia, 

 perfecta; carpella vulgo tomentella, stjii saepe rubri; fructus perfecti, ovoidei vel subgiobosi, in terris 

 calidioribus sapidi; putamen fere semicirculare, sed ambitus apicem versus minus arcuatus. 



Fl. in regionibus meridionalibus praecipue junio, in borealibus exeunte julio et augusto. 



Species, quoad characterem generalem, constans et, si formae hybridae negliguntur, bene definita, 

 scd in omnibus fere singulis partibus variabilis. Inter se igitur frutices promiscue crescentes saepe uno 

 alterove signo diversi videntur. Occurrunt turiones epruinosi vel densius villosi, aculei minores vel majores, 

 recti vel incurvi; foliola terminalia suborbicularia, obovato-cuneata, oblonga vel anguste elliptico- 

 lanccolata; serraturae foliolorum parvae, copiosae vel repando-remotae; inflorescentiae amplitudine 

 et figura diversae, ramuh villoso-tomentosi, flores majores vel minores, stamina brevia vel stylos longe 

 superantia, petala et filamenta alba. 



In R. abruplo foliola obtusissima breviter mucronata sunt. 



R. Frcuuipani est forma pusilla gracilis angustifolia rupestris, nullibi copiose reperta. 



R. Cahlcsianus habitu similis sed major est et in inflorescentia glandulas breviter stipitatas 

 paucas exhibens.
