V.c. 3, 4, 5, 6, 8, 10, 11, 12, 13, 14, 17, 20, 22, 23, 24, 26?, 32, 33, 

 34, 38, 55, 70?, 80. 



Var. operta (Pug.). Prickles few, sometimes none, leaflets large, 

 fruit ovoid, smooth. Y.c. 3, 6, 23, 24, 32, 34. 



Var. septicola (DesegL). Prickles many, stout, hooked, leaflets 

 large, fruit small, subglobose, somewhat glandular-hispid. V.c. 15. 



Var. trichocarpa Kouy. Like the type, but with acicles below 

 the inflorescence, leaflets oval-elliptical, and fruit roundish-ovoid, 

 hispid. V.c. 11 or 12, 15, 16, 17, 33, 58. 



Var. sylvicola (Desegl. & Kip.). Prickles long and straight, 

 with acicles below the inflorescence. V.c. 3 ?, 27 ?, 31, Q5. 



Var. hysfrix (Baker). Leaflets small, much narrowed at the base 

 like those of R. agresfis, fruit described as elongate, but more often 

 ovoid urceolate, small and somewhat glandular-hispid. V.c. 16 ?, 

 17?, 24, 32. 



Var. Lemanii (Bor.). Near var. liyatrix, but not synonymous, as 

 Boreau supposed, since its leaflets are quite rounded at the base, and 

 sometimes suborbicular. V.c. 6, 16, 17. 



Var. Briggsii Baker. Leaflets normally very large, but forms 

 occur with them normal, fruit and peduncles smooth. V.c. 3. 



3. Geoup or R. elliptica. 



Low erect habit of the R. ruhiginosa Group, leaflets small, sub- 

 obtuse, much narrowed at the base, peduncles rather short, smooth, 

 sepals spreading or suberect, styles short, hispid, or villous. 



B. elliptica var. Billietii (Pug.), Prickles stout, hooked, leaf- 

 lets rather small, obovate, peduncles hairy, fruit ovoid or urceolate, 

 styles villous or hispid. V.c. 6, 38. 



Var. crypfopoda (Baker). Prickles hooked but small, leaflets 

 glabrous above, thinly hairy beneath, rounded or only slightly narrowed 

 at base, subfoliar glands inconspicuous, petioles almost eglandular. 

 ])eduncles very short, fruit subglobose, styles in a woolly head. 

 Deseglise places it in this Group, but it seems much nearer the 

 (Joriifolice. V.c. 63 or 64. 



4. Geoup or R. ageestis. 



Habit of the JEu-canincs, though often dwarf in exposed situa- 

 tions. Leaflets narrowed at the base, peduncles rather long, smooth, 

 sepals reflexed and deciduous, styles glabrous. 



R. AGEESTIS Savi=_K. sepium Thuill. Prickles stout, hooked, 

 leaflets small, often very small, narrow, and attenuate at each end, fruit 

 ovoid, styles rarely slightly hispid. V.c. 6, 11, 17 ?, 23, Westmeath. 



f. suhcuneata Rouy. Leaflets larger, often but not always broader 

 and more obtuse, fruit ovoid or ellipsoid. V.c. 6, 14, 15, 17, 22 ?, 

 23, 24, 34, 49, Westmeath, Lough, Dearg. 



Var. Belnensis (Ozan.). Leaflets larger, broader, and more obtuse 

 than in the type, fruit globose or subglobose. V.c. 6, 14 ?, 15, 17. 



i. puhescens Rouy. Leaflets very large, 2 in. by 1\ in., very 

 pubescent, fruit ovoid. V.c. 14.
