1906] Blanchard,— Some Maine Rubi,— II J71 



New canes. Stems stout, erect, recurved above, 4 to 5 feet high, 

 6 to 8 feet long, reddish, glabrous and glandless, well angled and 

 furrowed. Prickles strong, straight, needle-pointed, -^-^ in. long, 

 6 to 10 to the inch of stem, set at a right angle to the stem and on its 

 angles only. Leaves large, 8 in. long by 7 in. wide, 5-foliate, quite 

 thick; yellow-green with appressed hairs but smooth on the upper 

 surface, and lighter and very softly pubescent beneath. Leaflets 

 stalked, broad-oval, outline entire, taper-pointed, ciliate, finely some- 

 what doubly serrate-dentate; the middle leaflet one-half as wide as 

 long, often wider, rounded or slightly cordate at the base; the side 

 ones nearly one-half as wide as long, broad at the base ; and the basal 

 ones similar in shape or broad-pointed at the base and smaller. Petiole 

 and petiolules stout, glandless, grooved, thinly pubescent; prickles 

 numerous, strong, hooked; the petiolule of the middle leaflet averaging 

 1 in. long, the side ones one-half as long, the basal leaflets on very 

 short stalks. 



Old caves. Erect, mostly killed back, often badly, prickles intact. 

 Normally pyramidal in outline, one bud developing from each old 

 leaf axil. New growth on the upper part of the cane consisting of a 

 short close raceme at the end of an axis 3 to 6 in. long, the shorter set 

 the farther up the cane; the lower part of the cane occupied by leafy 

 branches resembling the new canes, the basal ones 1 ft. or more long, 

 the upper ones 6 in. Axis of fruit branches stout, straight, terete, 

 glandless, very pubescent or woolly; prickles few and small, strong 

 and hooked; the racemes short, close; pedicels short, stout, pubescent, 

 glandless, set at a great angle to the axis, subtended by small bracts; 

 the leaves small and few, trifoliate with jiearly oblong leaflets. Axis 

 of leaf branches nearly terete, stout, nearly straight, pubescent; 

 prickles few, straight and small ; leaves very similar in color, texture, 

 pubescence, serration and form to those on new canes, mostly quinate, 

 a few at the base of the branch trifoliate with wide leaflets, petioles 

 and petiolules very pubescent; mostly tipped with a little loose in- 

 florescence. New growth on badly killed-back stems consisting of 

 long leaf branches tipped with late flowers, several from each old leaf 

 axil giving the cane a peculiar form. Flowers rather large, IJ to 1\ 

 in. broad, petals oval to oblong, f in. long and rather more than one- 

 half as wide as long, appearing the last of June, those on killed-back 

 branches continuing till the middle of July. Fruit short-cylindric, 

 about i in. high and broad, of 15 to 20 large drupelets. Ripe early 

 in August. 



Type stations: The Rosin dump below the Leatheroid shop and 

 the sand lot above Hope Cemetery in Kennebunk village, Maine. 

 Abundant on the meadows of the Mousam river below the village 

 and occurring in other places. Open sun, dry and moist ground. 



This species is well distinguished from R. nigrohaccus and R. 

 orarius by its long recurving stem, lack of glands, narrow leaflets
