16 A EEVISED ARHANGEMENT OF BEITISII EOSES 



1. GrROUF OF R. POMIFEEA. 



Of low growth, with straight stems and branches, prickles 

 normally rather long, straight, and slender, sejDals long and little 

 pinnate, usually fleshy at the base and not disarticulating, but 

 crowning the fruit till it falls. The leaflets are normall}" larger and 

 more rounded at the apex, with more compound toothing than in the 

 other two Groups, the auricles also are broader and falcately incurved 

 towards the petioles, and the armature of the peduncles and fruit 

 more aciculate. 



R. POMIFEEA Herrm. Leaflets very large, parallel-sided, said to 

 be thinner than in R. mollis, with or without subfoliar glands, petals 

 ciliate (?), and fruit violet when ripe (?). A doubtful native. 

 V.c. 15, 31., 77 ?, 80, 91, 98, 106. 



E,. MOLLIS Sm. Leaflets smaller and more oval, some subfoliar 

 glands always present, but very variable in quantity and often hidden 

 in the hairs, peduncles more or less densely glandular-hispid, but less 

 disposed to be aciculate than in B. pomtfera. V.c. 43, 57, 60, 62, 

 Go, m, 69, 70, 72, 73, 78, 80, 81, 85, 87, 90, Antrim. 



f. ccBVulea Woods (sub M. villosa). Peduncles and fruit smooth or 

 almost so. Woods says it is a smaller bush with more subfoliar glands. 

 V.c. 52, 57, 66, 69, 74, 79, 81, 85, 88, 89, 96 or 97, 108, Antrim. 



Var. Grenierii (Desegl.). All the characters of B. mollis, but 

 without subfoliar glands. A parallel form to f. ccBrulea occurs. 

 V.c. 36, 41, 42, 60, 62, 64, 69, 70, 75, 79, 80, 83, 92, 95. 



Var. 2^^^ii^^o-rubiffiiiosa (Lej.). Prickles usually few and very 

 long, leaflets smaller, narrower, darker green and more glabrous, and 

 more conspicuously glandular, sepals usually more pinnate. V.c. 17 

 (as an escape), 57 ?, 62, 6Q, 69, 78, 79, 88 ?, 89, 92 ?, Down. 



B. mollis X coriifolia. Leading features of B. mollis f. ccerulea, 

 but with stouter, longer-based prickles, more pinnate sepals, and with 

 appearance of the Glauca Group. V.c. 70. 



2. Geoup of R. omissa. 



Habit and technical characters just intermediate between the last 

 and next Groups, making its varieties often diflicult to assign to the 

 correct one. The book characters, as compared with the last one, 

 are stems and branches less straight, prickles more often unequal and 

 curved, with larger bases, leaflets smaller and more acute, auricles 

 more acuminate and not converging, sepals shorter and more pinnate, 

 erect or often only spreading, not fleshy at base, persistent till the 

 fruit is ripe, but not till it falls. In some varieties the styles are 

 hispid, not woolly. 



R. omissa Desegl. Prickles usually curved, sometimes straight, 

 leaflets smaller, narrower, and more acute than those of B. mollis^ 

 with subfoliar glands, peduncles often only half as long as fruit, 

 rarely as long, fruit subglobose, ovoid, or pyriform, smooth or slightly, 

 rarely densely glandular-hispid, sepals shorter and usually less erect 

 than in B. mollis, V.c. 33, 34, 36, 40, 41, 42, 54, 55, 57, 58, Q5, 

 73, 88, 96, 106. 



f. resinosoicles (Crep.). Prickles fewer, stout and curved, leaflets 

 with conspicuous subfoliar glands, fruit almost always glandular-
