A EEVISED AEEANGEMENT OF BEITISH EOSES ID 



petioles strongly armed, leaflets large, densely tomentose, with many 

 but often inconspicuous subfoliar glands, peduncles long, in a cluster, 

 strongly ghuulular-liispid as well as the ellipsoid fruit, sepals dark, 

 \ery glandular-hispid, loosely reflexed, styles glabrous, V.c. 32, oS. 



C. Subsection EuBiGiNOSiE. 



Subfoliar glands very numerous, conspicuous, often sticky, and 

 strongly scented. The other characters vary considerably. 



1. GeOUP of R. EUBiails^OSA. 



Low erect bushes, usually with unequal prickles, some of them 

 often reduced to acicles in clusters on the stems, and especially below 

 the inflorescence, leaflets small or rather small, roundish or oval, obtuse, 

 rounded at the base, peduncles rather short, glandular-hispid (except 

 in var. Jenensis), sepals spreading or suberect, subpersistent, stigmas 

 in a short hispid or villous head. 



R. EUBIGINOSA L. = i2. ajjrico^nim Vdip. Main prickles uniform, 

 stout, and hooked, with acicles as in the Group, leaflets medium or 

 small, pubescent at least on mid-ribs and primary nerves, fruit globose, 

 less frequentlv ovoid, sepals spreading or suberect, but falling before 

 the fruit ripens. V.c. 5 or 6, 11, 15, 17, 23, 24, 27, 32 ?, 87, 49, 69, 

 70 ?, 74, 78, 79, 80, 88, 89, 95, 96, Down. 



f. Gremlli Chr. is a name given by Crepin to a white-flowered 

 form, of which there several on the Continent. V.c. 89 ?. 



f. Corstopliincd (Druce). So far as I know this, it is only a 

 luxuriant form. V.c. 90. 



Var. comosa (liip.) has sepals erect and persistent till the fruit 

 ripens, fruit usually ovoid. V.c. 3, 8, 9, 16, 17, 26, 27 or 28, 72, 7S, 

 79, 80, 98, Down. 



f. comosella (Desegl. & Oz.). Near the last, but with straight 

 prickles. Leaflets sometimes as small as in var. rotundifolia, and 

 fruit sometimes with long eglandular acicles. V.c. 17, Down. 



Var. echinocaiya Gren. Prickles very numerous, the main 

 ones hooked but not always stout, mixed with many smaller straight 

 ones, peduncles and fruit with long eglandular acicles as well as 

 glandular setse, fruit large, broadly ovoid, sepals erect but not per- 

 sistent, styles hispid. V.c. 15, 17, 27 or 28, Perth. 



Var. rotundifolia Rau. A small bush with unequal straight, or 

 only slightly curved, often long, prickles, and very small suborbicular 

 leaflets, fruit rather small, subglobose or ovoid, smooth. V.c. 3. 9, 

 16, 17, 22, 40 ?, 62, 67 or 68. 



Var. Jeneiisis M. Schulze. Like the type, but fruit and peduncles 

 quite smooth. V.c. 15. 



2. Geoup of R. miceantha. 



Taller and less erect, like the Eu-canina. Prickles unifoi-m, 

 rarely with acicles under the inflorescence, leaflets larger, more acute, 

 and often less glandular, fruit more urceolate, sepals reflex( d, and 

 styles glabrous, usually exserted. 



R. MiCEANTHA Sm.=-B. permixta Desegh Characters of the 

 Group, leaflets variable in size, more or less pubescent beneath, rarely 

 glabrous, usually reddish when young, fruit glandular or smooth.
