156 ICOSAND. POLYGYN. 



stinct, usually much shorter than the ripe fruit. Fruit either purple 

 or deep reel, round., with a thickened short peduncle, covered with 

 stiff setae, and crowned by the connivent, pale brown, clammy 

 segments of the calyx. 



" This Rose most nearly approaches R. tomentosa, but the fruit of the 

 latter is never more than hispid, whilst that of the former has a con- 

 siderable number of rigid bristles, and even prickles, scattered over 

 its surface." L. 



6. R. lomentosa (downy -leaved Dog Rose), leaflets ovate ra- 

 ther acute, fruit hispid or naked. LindLp.ll. 



a., vera, shoots bent, segments of the calyx compound. R. to- 

 mentosa, E. B. t. 990, et t. 1896 (R. scabriuscula). 



jS. mollisy shoots straight, segments of the calyx subsimple.

 R. pulchella, Woods.

" Seven or eight feet high, spreading, very gray. Brandies somewhat 

 glaucous, armed with straight (rarely falcate), equal, scattered 

 prickles and without setee. Leaves hoary with down ; stipules con- 

 cave, dilated, toothletted and fringed with glands -, petioles slightly 

 prickly and glandular ; leaflets about 5, oblong or ovate, obtuse, 

 doubly serrated ; serratures diverging, rarely converging j soft and 

 rugose, paler beneath, and sometimes slightly glandular j when 

 bruised having a turpentine smell. Flowers one or more, reddish, 

 cup-shaped, with short stalks ; bracteas ovate or oblong, downy, 

 longer or shorter than the peduncles, which are hispid with unequal 

 setae and glands - } tube of the calyx ovate, oblong or round, usually 

 hispid, sometimes nearly smooth; segments of the calyx compound, 

 spreading, always hispid at the back ; petals entire, obcordate, con- 

 cave ; disk thickened, flat; styles very hairy, distinct. Fruit some- 

 what purple, round or obovate, or depressed, usually hispid, 

 crowned by the converging calycine segments, which sometimes 

 however fall off immediately after the fruit is ripe. 



" An extremely variable species, and closely allied to R. canina. The 

 marks of difference are the straight prickles, diverging serratures, 

 hispid fruit, calycine segments and peduncles, and soft leaves of the 

 former, as contrasted with the hooked prickles, converging serra- 

 tures, smooth calyx and its deciduous segments, and naked or 

 harshly pubescent leaves of the latter." L. 



RuBiGiNOS^E. Prickles unequal, sometimes setiform, rarely (if 

 ever) none. Leaflets ovate or oblong, glandular, with the serratures 

 divergent. Segments of the calyx persistent. Disk incrassated. 

 Shoots bent. (This division is remarkable for the numerous glands 

 on the lower surface of the leaves. R. tomentosa has sometimes 

 glandular leaves, and in such case the inequality of the prickles of 

 the Rubigmostf, and their red fruit, can alone distinguish them.)
