188 Mi: Woods 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. Doiiiana by which 

 these species may be distinguished, the pecuHar length, slender- 

 ness, and apparent weakness of the second peduncle of R. gracilis 

 may be mentioned. From R. Sabini it may be known by the 

 simple leaves of the calyx. 



7. Rosa Sabini. 

 R. ebracteata, caulibus setigeris, receptaculis globosis, calycibus 

 compositis, foliolis duplicato-serratis. 



Frutex 4 — 6-pedalis. Rami vagi, fusci, aculeis sparsis, inaequalibus, rectis, tandem in setas 

 immiitatis muniti. Petioli villosi, glandiilosi, aculeati ; aculei minimi, recti. Sti- 

 pulcB lineares, glanduloso-ciliatae, eae fioribus propiores aVuiuantulum latioies, his fo- 

 lia interdum desunt et bracteae parvae ovata; fiunt. Foliola 5 vel 7, quorum par superius 

 et foiiolum impar ceteris majora, omnia elliptica, duplicato-serrata, suhtus venuiosa, 

 venulis hirsutis, interdum etiani nervo et margine glandulosa, superficie quoque supe- 

 riore pilis sparsis hispida. Pedimaili 1 — 3, filiformes, setis inaequalibus obsiti. Re- 

 ceptaculum globosum, olivaceum, setis sicut in peduncuiis munitum, Calycis foliola 

 composita, pinnulis angustissimis, nee raro capiliaribus setosa, giandulosaque. Flares 

 nibescentes, expansi, magni. Slyli subinclusi, stigmatibus villosis. Frnclus 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 setae 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 otlier British setigerous Roses 

 jR. Sabini is distinguished by the divided leafits of the calyx : the 



segments
