midable, numerous and large, about 13 to an inch of stem, 0.25 

 inch long on the main axis and set at a pronounced backward 

 slant, smaller on the branches and often hooked, set in lines more 

 or less regular on the angles. Leaves large, mostly 3-foliolate, 

 many or all on the main axis and often some on the branches 5- 

 foliolate, yellow-green, with abundant appressed hairs on the upper 

 surface, quite pubescent below. Leaflets broad, the middle one 

 often nearly orbicular, short-pointed, the side ones also broad 

 and more or less i -incised, or if divided the side leaflets rhom- 

 boidal and pointed at each end and the basal ones similar but 

 smaller; outline finely somewhat doubly serrate-dentate, other- 

 wise nearly entire. Petiole and petiolules large, grooved, some- 

 what pubescent, strongly armed with three rows of numerous 

 very stout and hooked prickles, which are continued into the point 

 of the leaf, the petiolule of the middle leaflet often i inch long, 

 the other leaflets nearly or quite sessile. 



Old canes. — Stems greenish, stout, hard, prickles intact. 

 Second year's growth consisting of short fruit-branches from 7 

 inches to 2 inches long, well graded, tipped with inflorescence, 

 one from each old leaf-axil, axis of branch zigzag, angled, fine- 

 hairy, armed with short, stout, hooked prickles. Leaves not nu- 

 merous, the lower 3-foliolate, the upper unifoliate ; leaflets rather 

 broad, very coarsely serrate-dentate, often incised-dentate, the 

 unifoliate ones often 2-incised, similar in color and pubescence 

 to those on new canes. Liflorescence cymose-racemose, of 4 to 

 8 flowers on stout pedicels, fine-hairy, well armed with hooked 

 prickles. Flowers not seen. Fruit ripening early in August, 

 abundant, short-c\'lindric with large drupelets ; a large one meas- 

 uring 0.75 inch high by 0.69 inch broad and having 30 drupe- 

 lets, each 0.22 inch in diameter. Type station : Rocky Point, 

 Rhode Island. 



In open dry places. 



This species has the appearance of a high blackberry in its 

 leaves and angled stem, round stems being commonly character- 

 istic of recurring and decumbent forms. It trails over walls and 

 fences and alone makes a low hedge of the densest kind. The 

 fruit is ripe considerably earlier than that of R. Andrcusiaiiiis 

 Blanchard and much earlier than that of R. alleghaniensis Porter.
