ICOSANDRIA— POLYGYNIA. Rosa. 375 



leq/fets,Jlower-stalks, and segments of the calyx, sometimes on 

 the lower part of its tube. The footstalks are often prickly be- 

 sides. The siipulas are glandular at tlie margin, dilated, undu- 

 lated, and leafy, but hardly ever become bracteas, though I have 

 an example or two of such a change. Leajlets from 7 to 1 1, not 

 more, broadly elliptical and bluntish, with broad, acute, mostly 

 simple, rarely notched or glandular, serratures ; smooth and 

 green on both sides, except the rib; paler beneath. Mr. Woods 

 has remarked a few chaffy scales at the insertion of the leaflets. 

 Flower-stalks solitary, simple, rough with glandular bristles. 

 F/. either blush-coloured, or white blotched with pink. Seg- 

 ments of the calyx quite simple, reddish ; slightly downy on 

 the inner side ; bristly at the back, like some of the lower por- 

 tion of its tube. Fruit bright scarlet, globular, with a short 

 neck, and crowned with the limb of the calyx. 



The colour of the fruit, though it cannot well enter into a spe- 

 cific definition, affords a striking distinction between this and 

 the following species. The supposed variety from Mr. Lee's 

 nursery, bearing a short blackish fruit, as described by 

 Mr. Lindley, was, I am told, a foreign plant, and it appears 

 that R. rubella of this author is different from my original one, 

 whose fruit is neither elongated, nor I believe pendulous. 

 R. pendulina of Roth (not pendula) is taken up by that writer on 

 report, and can be of no authority ; and the only clear point in 

 the history of Pallas 's R. alpina in, as Mr. Lindley justly deter- 

 mines, that it is different from the Linnsean plant, so well 

 known in Switzerland, as n. 1107 of Haller. The account of 

 R. rubella in English Botany, is, I believe, correct. 



The authentic specimen of R. pimpinellifolia, marked A, in the 

 Linnaean herbarium, has smooth flower-stalks, and a globose 

 smooth calyx-tube, without a neck. It cannot therefore belong, 

 as Mr. Woods suspected, to this species, but is truly the fol- 

 lowing, under which I shall give its history. The prickly, or 

 rather perhaps bristly -stalked variety of spinosissima quoted in 

 Fl. Br. from Withering, should seem by that character to belong 

 to rubella, but this is contradicted by Mr. Winch, Geogr. Dis- 

 trib. 40. 



3. R. spinosissima. Burnet Rose. 



Flower-stalks without bracteas, mostly smooth, as well as 

 the simple calyx. Fruit globose, abrupt, somewhat de- 

 pressed. Prickles of the stem straight, unequal, nu- 

 merous, intermixed with glandular bristles. Leaflets 

 roundish, smooth, with simple serratures.
