Flor. juras., p. 243 (pro var. R. caninœ ); var. dissimula H. Braun, 
nov. var. 
Rami elongati, aculeis inclinatis robustis armati, laxefoliacei. Rami florigeri 
subinermes inermesque, virentes. Stipulæ ut in Rosa insigni typica. Petioli 
glandulosi et aculeolis flavescentibus armati, in infirma parte parce pilosuli. 
Foliola 5-7, elliptica vel elliptico-obovata, mediocria, utrinque glaberrima, 
supra obscure vel fiavescenti-viridia, subtus glaucescentia, apicem basinque 
versus acuta, ad basin sæpe subcuneata, in cosla media parum glandulosa, ad 
marginem argute glanduloso-bi- vel subcomposito-serrata, lateralia breviter, 
terminalia longe petiolulata. Pedunculi circiter 8-10 mil. longi læves. Recep- 
tacula ovoideo-ellipsoidea, superne attenuata. Sepala pinnulis anguslis, plus 
minus glandulosis, in dorso eglandulosa, post anthesin reflexa, citi decidua. 
Styli leviter pilosi, subglabri, discum eximie superantes. Discus planus. Recep- 
tacula fructifera ovoideo-ellipsoidea, superne attenuata vel substrangulata. 
Petala pallide rosea. 
In calcareis pagi Medun.

Frutex dense ramificatus. Rami purpurei vel subvirescentes, diffusi, flexuosi, 
aculeati. Aculei graciles, inclinati vel subfalcati vel bine inde subrecti, basin 
versus dilatati, purpurei vel glaucescentes. Stipulæ anguste lanceolatæ, in 
ramis superioribus dilatatæ, utrinque glabræ, in margine glandulis purpuras- 
centibus vel atropurpurascentibus stipitalis plus minus præditæ vel subleves, 
auriculis acuminatis divergentibus vel subporrectis. Petioli purpurascentes 
aculeolati, glabri, glandulis stipitatis purpurascentibus bine inde, sed sparse 
præditi. Foliola parva, 8-13 mil. longa, 6-8 mil. lata, elliptica vel elliptico- 
obovata, basin versus subattenuala vel bine inde anguste rotundata, ad apicem 
acuta, utrinque glabra, lateralia breviter petiolulata vel subsessilia, supra satu- 
rate viridia, subtus pallidiora et in nervo primario eglandulosa, vel precipue 
in foliolis terminalibus, bine inde glandulis rubescentibus et aculeolis llavescen- 
tibus sparse obsila, in marginibus simpliciter vel subirregulariter serrata, 
serratura eglandulosa. Serraturæ dentes convergentes, sæpe submucronulati. 
Bracteæ dilatatæ sæpe foliaceæ, pedunculis longiores. Pedunculi brèves, setis 
glandulosis obtecti vel subleves. Receptacula ovoideo-globosa, sparse setis 
glanduliferis obtecta. Sepala duo integra, tria pinnatifida, in dorso glabra vel 
bine inde unum alterumve seta glandulifera obtectum, post anthesin reflexa, 
cito decidua. Styli hirsuti, discus planus. Receptacula fructifera parva, pisi 
magnitudine (8-10 mil. longa, 7-9 mil. lata), globosa vel subglobosa, setis 
glanduliferis una alterave obtecta. 
In saxosis castri Medun.

Frutex dense ramificatus, cortice brunneo vel violascenti rubro. Rami elongati, 
bine inde virgati, dense aculeati. Aculei robusti, falcati basin versus dilatati, 
cinerei vel subalbicantes, bine inde subgeminati. Rami fertiles subflexuosi,
