and the herbaria collections mostly are such, but it is often of a very 

 robust nature especially in elevated situations and on bleak shores. 

 These forms seem to make it desirable to have them segregated as a 

 variety. 



Var. major, n. var. Plants much larger in every way, the stem 

 often densely covered with rather strong bristles, leaves much larger, 

 leaflets on new canes often 3 in. long, frequently pointed and serrate, 

 sometimes narrow; varying in a similar manner on the old canes. 

 Tendency to climb over bushes much greater. 



RuBUS SETOSUS Bigelow. {R. nigriran.,t, Rydberg.) Plants with 

 the neiv canes generally erect, sometimes decumbent, 1^ to 3 ft. high 

 or often 4 ft.; stems seldom branched, terete or slightly angled, thick 

 at the base and soft, clothed with numerous bristles varying from 200 

 soft ones to 100 or less strong ones to the inch of stem, the former set 

 at a right angle to the stem and the latter strongly retrorse, more or 

 less of the smaller bristles and hairs bearing small glands at the end. 

 Leaves often large, 4 in. wide, varying from light yellow-green to dark 

 green, not thick but firm, nearly or quite glabrous, a few appressed 

 hairs above and some close pubescence below not rare, mostly 5- 

 foliate, a few of the lower leaves 3-foliate; leaflets oval or rhom- 

 boidal, rather cuneate and well pointed; serrate, or serrate-dentate 

 toward the points, the middle one about 3 in. long and 1| in. wide, 

 the others similar in shape but smaller; petiole and petiolules resem- 

 bling the stem in bristles and glands, the petiolule of the middle leaflet 

 J of an inch long, the side ones shorter and the basal leaflets sessile. 



Old canes often decumbent or prostrate, badly killed back especially 

 on large canes, bristles generally much im[)aired. Second year's 

 growth consisting of leafy erect or upward s])reading fruit branches 

 tip])ed with a racemose often branched inflorescence; branches very 

 variable in length, generally one from each old leaf-axil or several 

 from the upper if badly killed back. Axis seldom straight, weakly 

 armed or merely his])id; leaves 3-foliate or part of them o-foliate; 

 leaflets ])ointed at each end, varying from narrow to wide, serrate- 

 dentate; in texture and color much like those on new canes. Uni- 

 foliate leaves few none or rarely many. Pedicels and calyx lobes 

 generally hispid often densely so with abundant glanded hairs, or 

 sometimes nearly naked. Flowers ajipearing very late rather showy, 

 1 in. broad more or less, petals usually narrow, less than one-half as 

 wide as long. Fruit ripening late globose, small and sour, or often 

 quite large and edible. 



Grows everywhere in these towns, the rankest plants in the richest 

 and most favored spots. Farther south and in less exposed places 

 it seems to be most at home in moist situaticMis. 



Dr. Rydberg's R. nigricans is a synonym for this species and the 

 injection of this name has tended to make confusion. There are
