2, Rosa RUBELLA. 
R. ebracteata, caulibus setigcris, receptaculis suburceolaribus, 
serraturis foliolorum simplicibus, aculeis perpaucis gracil- 
-limis subæqualibus. Ţ 
-R. rubella. Eng. Bot. xxxvi. t. 2521. 
Frutex erectus, 3—4-pedalis; in sabulosis maritimis vix sesquipedalis. Rami breves, 
fusci, aculeis rectiusculis, gracillimis, setisque confertis instructi, Petioli glandulosi, 
foliorum ad ortum superne subacerosi, cetera nudi. Stipule lineares, margine glan- 
dulosæ, subæquales, Foliola 7 ad 11 paria, quorum duo vel tria summa ejusdem 
cum foliolo impari magnitudinis, reliqua sensim minora; omnia elliptica, obtusa, 
simpliciter serrata, utrinque glabra, supra viridiora, subtus pallidiora. Pedunculi so- 
litarii, filiformes, setis longiusculis tenerrimis vestiti. Receptaculum basi globosum, 
superne aliquantulum urceolatum ; nunc glabrum, nunc setis sparsis instructum, atro- 
rufum, nitidum. Calycis foliola triangularia, subulata, simplicia, setosa. Flores rubelli, 
aut interdum rubri, vel variegati. Styli inclusi ; stigmatibus planiusculis. Fructus sub- 
globosus, superne receptaculi instar ad formam urceolatam accedens [coccineus, Sm.]. 
Mr. Winch finds this species on the sands of the sea-shore in 
Northumberland, mixed with R. spinosissima : it is also said to 
have been brought som Scotland. The ripe fruit I have never 
seen. 
The resemblance of R. rubella to R. spinosissima may perhaps 
have occasioned it to have been so long overlooked ; though the 
stems and branches covered with setze, intermixed with a very few 
_slender aculei, sufficiently distinguish it. The simple serratures 
of the leaflets will not suffer it to be confonaded with R. involuta 
or R. Doniana.’ 
- The specimen of n. pimpinellifolia i in the nan Herbarium 
considerably resembles this species; but it is not sufficiently 
perfect to enable me to pronounce with confidence: I have there- 
fore preserved the name given to itin English Botany. Perhaps 
some other authors may also have intended this plant by R. pim- 
pinellifolia; but I have not been able to unravel their synonyms 
from those of R. spinosissima.
