Rosa.] xlviii. rosacea (oliver). 381 



toothed. Petals 5, sessile, spreading*. Stamens indefinite, inserted in 

 mouth of calyx-tube ; filaments free, filiform. Carpels indefinite, free, 

 sessile at base of calyx-tube ; ovary 1 -celled, with a pendulous ovule. 

 Achenes indefinite, included in the fleshy persistent calyx-tube. — 

 Shrubs, often scandent ; usually aculeate. Leaves alternate, imparipin- 

 nate ; stipules adnate to the petiole. Flowers solitary, or in corymbose 

 cymes, white, red or yellow. 



A considerable genus, several of the species of which are very variable ; most abun- 

 'dant in the north temperate zone of the Old World. 



1. R. abyssinica, R. Br. in Salt. App. 64 ; Lindl. Ros. Monog. 116, 

 1. 13, Scandent ; branches glabrous, aculei scattered or rather crowded, 

 more or less recurved. Leaves 5-7-foliolate, ovate-elliptical or ellip- 

 tical, broadly pointed or obtuse, rounded at base (cuneate in Lindley's 

 figure), acutely and nearly simply serrate, glabrous ; rachis minutely 

 glandular, sparingly aculeate ; stipules gland-margined. Flowers 

 usually in terminal corymbose cymes of 2—6 or 8 or subsolitary ; bracts 

 linear-lanceolate, acuminate ; peduncles and calyx minutely appressed 

 pubescent or puberulous. Calyx-teeth lanceolate, elongate-acuminate, 

 3 with 1-3 short setiform segments below. Styles free, exserted, very 

 thinly pilose above. Fruit (fide Rich.) ovoid, glabrous, apex truncate.

Nile Land. Abyssinia, Schimper! Salt, and others. (Var. with glabrate or 

 minutely glandular peduncles. Ankober, Abyssinia, Dr. Roth !) 



Probably, not specifically distinct from some extra-African form, but it would be un- 

 safe to identify it with our small material. Dr. Lindley (1 c.) puts it near R. semper- 

 virens ; Mr. Baker suggests that it may be a form of R. systyla. 



We have besides from Ankober, collected by Dr. Roth, a solitary specimen, perhaps 

 a variety of the foregoing, which approaches R. moschata in its many flowered inflo- 

 rescence. 



Richard (Fl. Abyss, i. 262) describes, under the name R. sancta, a Rose cultivated 

 around churches in the province of Tigre, which he says is nearly identical in habit 

 with R. centifolia, L., differing in its glabrous glaucous eglandular branches, armed 

 with but few recurved aculei, and in its much smaller flowers, with glaucous glabrous 

 peduncles. I have not seen a specimen. 



11. NETJRADA, Linn. ; Benth. et Hook. f. Gen. Plant, i. 625. 



Calyx-tube shallow, cupuliform, at length nearly flat below, de- 

 pressed conical above, contracted and shortly 5-lobed at the mouth, 

 lobes deltoid or ovate-lanceolate, alternating with as many exterior 

 subulate or at length aculeiform bracteoles. Petals, 5, inserted in throat, 

 obovate-cuneate or oblanceolate, very small and little exceeding the 

 calyx. Stamens 10 (or thereabouts), short, distinct, inserted in throat 

 of calyx ; anthers 2-celled. Carpels 10 (or more ?), more or less cohe- 

 rent and adnate with the calyx ;- ovaries, at least the outer whorl, 

 horizontal, narrowed into the scarcely exserted styles. Ovule solitary. 

 Fruit dry, orbicular, depressed-conical, spinose-muricate, tomentose, 

 often persisting long after germination of one or more of its seeds. —
