Rosa. ROSACEiE. 461 



crowded on tlie flowering branches and often fascicled : leaflets somotiiiit-s 

 only luilf an inch in length. Flowers small, apparently rose-color; the ))c- 

 d uncles i-i an inch in length. 



■J 10. R. gynmocarpa (Nutt. ! mss.) : " branches glabrous, furnished wiih 

 scattered slender and straight weak deciduous jjrickles ; leaflets 5-9, glabrous, 

 rather distant, oval, sharply doubly serrate ; the serratures, as well as the 

 l)eti()les antl peduncles, glandular ; stipules broad and short, glandular-ser- 

 rulate ; flowers (very small) solitiyy or sometimes in pairs ; segments of the 

 calyx ovale, witli a simple acumination, deciduous; the tube glabrous; fruit 

 oval (red), smc^jth and naked." 



Oregon, in sliady woods, common, Nultall ! Douglas ! — This species 

 belongs to the X)ti if- 7iwe section. The flowers are remarkably small, red ; 

 and the fruit about the size of a small pea. The slender petioles are often 

 slightly bristly. 



11. R. stricta (Lindl.) : much branched ; stems armed with numerous 

 setaceous scattered, often deciduous prickles ; flowering branches mostly 

 naked ; leaflets 7-9, oval, firm, glabrous, not shining, the petiole glandular- 

 hispid ; sti])ulcs lanceolate, mostly glandular-ciliate ; flowers 1-3, on gla- 

 brous or glandidar-hispid peduncles ; calyx-segments spreading ; fruit ovoid, 

 pendulous. — Lindl.! Ron. p. 42, t. 7 ; Scringe, in DC. I. c. R. pendulina,

/?. lower surface of tlie leaves pubescent. Hoolc. Jl. Bor.-Am. 1. j). 200. 



On the Saskatchawan (/?.), Drummond. — This species is perhaps too closely 

 allied to R. alpina. We are confident that it has never been found within 

 the limits of tlie United States. For this species Lindley rpiotes Muhlen- 

 berg's Catalogue : but Muhlenberg seems not to know the ])lant (giving no 

 locality or observation), and refers to Donn for the name. The species was 

 established on garden specimens, which may or may not have been of 

 American origin. It is uncertain whether the plant figured by Dillenius 

 {Elth. t. 24.5, /. 317) belongs to R. alpina or the present species. On it R. 

 pendula of Linna;us (wlio states it to be a native of Europe), is founded, 

 and doubtless R. pendulina, Ait., which Seringe considers a variety of R. 

 alpina.

12. 7?. ruhiginosa (Linn.) : branches (yellowish-green) armed with scat- 

 tered very strong somewhat recurved prickles ; leaflets 5-7, roundish-oval 

 or obovate, sharply serrate, the margins, with the lower surface and stipules, 

 more or less clothed with ferruginous glands; flowers mostlj^ solitary, on short 

 bristly-hispid peduncles; fruit ovoid or obovate (reddish-orange when ma- 

 ture), somewhat hispid or unarmed when young. — Linn.! manf. j^;. 564 ;

 I. c. R. suaveolens, Pursh, Jl. 1. j^- 346. 



In waste places, road sides, and cultivated grounds throughout the United 

 States ; perfectly naturalized in many places. June-July. — Leaves some- 

 what viscid, and very fragrant. Calyx-scgmcnts either laciniate or entire. 

 Petals pale red, turamg white, emarginate. — The R. suaveolens is only a 

 variety of this species with nearly straight and more slender prickles. — 

 Eglantine. Sweet Brier. 



13. R. lesvigata (Michx.) : very glabrous; branches armed -vvith very strong 

 often geminate curved prickles ; leaves 3- (sometimes 5- ) foliolate ; leaflets 

 coriaceous, shining, sharply serrate ; stipules setaceous, deciduous ; flowers 

 solitary, terminal; tube of the calyx ovoid, muricate with long prickly 

 bristles.— M?c/?.r. / Jl. 1. p. 295; Ell. sk. 1. p. 566. R. Sinica, Ait. Kew.
