of Mahonia are really stipules, then that species comes 

 here. It is an evergreen with dark hard foliage, and 

 spinescent-toothed leaflets (see p. 162).] 



* Venation, petioles and shoots more or less 

 armed with true prickles. Leaflets few, 

 about 5 7 (3 9). Stipules more or less 

 adnate to the petiole. 



t Leaflets relatively large and broad ; the 

 whole leaf spreading, and often sub-palmate 

 in appearance. Stipules small, subulate or 

 linear, inserted above the base of the 

 petiole. 



Prickles of the terete, and downy or glaucous 

 shoots, straight and slender. 



Rubus Idceus, L. Raspberry (Fig. 38). Leaves 10 25 

 cm. long, trifoliolate above; the lower and those of suckers 

 with 5 leaflets. Leaflets 9 15 cm. long, nearly glabrous 

 above, rugose and dark green; grey- or white-tomentose or 

 hoary beneath ; ovate or elliptic, to rounded or long-ovate, 

 the terminal one cordate at the base and on a long petio- 

 lule; the lateral sessile, soft, unequally or doubly and 

 acutely serrate, or somewhat cut ; 4 10 x 2 7 cm., ob- 

 lique, not overlapping. Stipules small, filamentous or 

 subulate, adnate half-way. Rachis prickly. Stem erect, 

 terete and pruinose. 



Venation pinnate, like that of R. fruticosus. Leaves 

 purplish in autumn. 



Prickles of the angular downy shoots, 

 stout and recurved.
