New canes. Stems strong^ erect, 3 to B feet high, tlark red, often 

 branched, glabrous and ghmdless, angled and deeply furrowed. 

 Prickles few, 3 to 5 to the inch of stem, short, stout and strong, 

 straight, set perpendicular to it and on its sharp angles. Leaves large 

 often 9 in. long and 8 in. wide, 5-foliate, rather thick; dark yellow- 

 green, glabrous or somewhat hairy on the upper slirface, and glabrous 

 or more or less finely pubescent and lighter beneath. Leaflets broadly 

 oval or ovate, long-stalked, outline entire, taper-pointed, finely and

 the side ones narrower and rounded at the base; the basal ones smaller 

 and broadly cuneate at the base. Petiole and petiolules large, grooved 

 more or less, pubescent; prickles few, short and hooked; the petiolule 

 of the middle leaflet 1^ in. long, the side ones one-half as long and the 

 basal ones | in. long. 



0/(1 caites. Little changed, jirickles intact. Cane pyramidal in 

 outline, the new growth consisting of nearly leafless racemes at the 

 ujjper part of the stem and long leafy branches below resembling new- 

 canes, generally one from each old leaf axil. Axis of long leaf-branches 

 zigzag, terete, pubescent, prickles few and straight. Leave.*? 3-foliate 

 or some of the outer 5-foliate resembling those on new canes. Racemes 

 3 to 5 in. long; axis straight, stout, pubescent, glandless or with few 

 sometimes many stalked glands; prickles few, small and straight; 

 pedicels similar, slender, 1 in. long, set at a great angle and subtended 

 by small bracts; leaves two or three, very small, trifoliate and uni- 

 foliate. Flowers appearing the last week in June, large ami showy; 

 1} in. broad; the petals oblong-oval two thirds as wide as long; sepals

 Aug. 5 and continuing a long time, broad-cylindric, drupelets large, 

 j\ in. in diameter or sometimes but I inch. Two measured and 

 ccumted: ^ in. long by f in. broad, 23 drupelets; | in. high and ^ in. 

 broad, 43 drupelets. Edible and valuable. 



Type station Cape Porpoise post-office and from thence up the ' 

 Biddeford road in Kennebunkport, Maine. Quite variable and 

 abundant in Wells, Kennebunk and Kennebunkport. Moist or dry 

 ground, in open sun or light shade. 



This broad-leaved blackberry is well distinguished from R. nigw- 

 baccus by its broad petals, short fruit, dark yellowTgreen leaves and 

 in its being nearly or entirely lacking in pubescence and stalked glands. 

 It is the species that furnishes most of the fruit actually picked where 

 R. nigrohaccus is scarce. 



■<- H- The Argutus class. Inflorescence a short raceme with short stout 



unequal pedicels. 



Rubus amnicolus n. sp. Plants erect, tall, recurved at the top, 

 glandless, well-armed, pubescent. Fruit large, cylindrical; drupelets 

 large. Inflorescence a raceme leafy at the base.
