188 Mr. Woops on the British Species of Rosa. 
probably owing to none having been sent by Mr. Robson with 
his specimen. 
Besides the marks enumerated under R. Doniana by which 
these species may be distinguished, the peculiar length, slender- 
ness, and apparent weakness of the second peduncle of R. gracilis 
may be mentioned. From R. Sabini it mé be known by the 
simple leaves of the calyx. 
7. Rosa SABINI. 
R. ebracteata, caulibus setigeris, receptaculis globosis, pa per 
compositis, foliolis duplicato-serratis. 
Frutex 4—6-pedalis. Rami vagi, fusci, aculeis sparsis, inæqualibus, rectis, tandem in setas 
immutatis muniti. Petioli villosi, glandulosi, aculeati ; aculei minimi, recti. Sti- 
pulæ lineares, glanduloso-ciliatæ, ex fic or ibus propiores aliquantulum latiores, his fo- 
lia interdum desunt et bracteæ parvae ovate fiunt. Foliola 5 vel 7, quorum par superius 
et foliolum i impar ceteris majora, omnia elliptica, duplicato-serrata, subtus venulosa, 
 venulis hirsutis, interdum etiam nervo et margine glandulosa, superficie quoque supe- 
riore pilis sparsis hispida. Pedunculi 1—3, filiformes, setis inæqualibus obsiti. Re- 
ceptaculum globosum, olivaceum, setis sicut in peduneulis munitum. Calycis foliola 
composita, pinnulis angustissimis, nec raro capillaribus setosa, glandulosaque. Flores 
ruhescentes, expansi, magni. S/yli subinclusi, stigmatibus villosis. Fructus globo- 
sus: qui sit in maturo color nescio. 
Mr.Sabine received this Rose from Mr. Vere’s garden, where it was 
introduced by Mr. Jackson from Scotland. Mr. Borrer found it 
in the neighbourhood of Dunkeld ; and I have noticed it near 
Hawes-Water in Cumberland. 
The sete will always readily determine the family to which 
this Rose belongs, if examined on the living plant or in good spe- 
cimens; but I know no way by which to determine with any 
certainty specimens of Roses exhibiting only the flowering shoot 
and two or three leaves. From all other British setigerous Rose 
R. Sabini is distinguished by the divided leafits of the calyx: the 
segments
