ON ROSA SEPTUM. 79 



tube narrow-obovoid, quite free from aciculi and glandular sette. 

 Sepals 8-9 lines long, naked on the back, the main ones copiously 

 compound, with a slightly foliaceous elongated point and 2 or 3 

 linear pinnae on each side. Petals pinkish, 6-8 lines deep, the ex- 

 panded corolla an inch or an inch and a quarter across. Styles 

 glabrous. Fruit (not seen in the English specimen) narrow-obovoid- 

 urceolate, 7-8 lines long, quite glabrous, the sepals subpersistent, the 

 disk moderately developed. 



This form is one of the commonest Roses of the southern half of 

 Europe, reaching northward to Belgium, and. eastward certainly to the 

 Tyrol, and probably further. From R. Billietii, Puget {R. sepiiim, 

 Borrer in E. B. S. t. 2653), it differs by its leaves glabrous and more 

 densely glandular on the under surface, terminal leaflet narrower and 

 more narrowed from the middle to both ends, glabrous styles and 

 narrower fruit. R. agrestis, Savi, Fl. Pisana, vol. i. p. 475 ; Desegl. 

 Mon. p. 104; Exsic. p. 33, is a variety with still smaller leaves and 

 flowers, white corolla and shorter fruit. If I were to plan out my 

 monograph now, I should incline to place this, as the most widely-dis- 

 tributed and best and longest known of the forms, as the typical plant, 

 making Billietii, cryptopoda, and pulverulenta varieties of it. A con- 

 siderable number of other South European forms would also, according 

 to the plan of subordination there followed, rank as varieties here, but 

 this point it is not necessary to follow out now. Taking the species as a 

 whole, it comes very near micrantha, differing principally in its naked 

 peduncles and calyx-tube, and sepals not glandular on the back. 



R. obtusifolia, Desv. This variety of caniua, which I have been for 

 many years expecting to meet with as British, has been gathered by 

 Dr. St. Brody lately in two places (near Berkeley, and on St. Vin- 

 cent's rocks) in Gloucestershire. It is briefly noticed at page 229 

 of my monograph, and, according to the plan of arrangement there 

 adopted, ranks next to var. dumetorum, in the set of forms with de- 

 ciduous sepals, naked peduncles, and leaves hairy on both sides. It is 

 a plant which is widely, spread, and which has been distinguished by 

 many Continental authors and the following is a selection from its 

 synonyms : —
