small Jangle to the axis, subtended by uitifoliate leaves and small bracts. 

 The short inflorescences quite similar. Flowers appearing July ], 

 from 1 to 1^ in. broad; petals oblong-oval, two-thirds as wide as long; 

 sepals broad, very pubescent, mucronate or acuminate. Fruit ripen- 

 ing about Aug. 10, globose, drujielets large, maturing this year but 

 little and that very poor. 



Type stations: near Arundel railroad station in Kennebunkpori, 

 Maine, and Grand View Hill west of the Casino in KennebunkiMirt 

 village. Frequent throughout the village and especially abundant 

 along the shore from Spouting Rock to Cape Arundel. Also at the 

 (iranite Quarry in Biddeford. Open places in dry or rich ground, 

 tlwarf or large. 



The new canes resemble those of R. Arundelanus, but the old ones 

 are unique in their polymorphous and mixed characteristics. 



H — -I— Leaves glabrous; stems much prostrate. 



Rubus biformispinus, n. sjx Plants decumbent at length trailing, 

 with stems thick at the base, glabrous but very glandular, and with 

 very broad leaflets and distinct primary and secondary prickles, very 

 savage to touch. 



New canes. Stems thick and erect at the base, angled but not 

 furrowed, soon decumbent and then trailing, tipping in September; 

 trailing over bushes, fences or on the ground; glabrous but very 

 glandular; dark red on the upper side and green beneath. Prickles 

 of two kinds: primary ones strong, ^\ in. long, with stout base, 5 to 

 10 to the inch of stem, straight, on the angles, with slight backward 

 slant or none; secondary prickles short, strong, of varying lengths 

 set at random, the smallest tipped with glands. Glands numerous, 

 their stalks unequal in length, tapering. Leaves about 6 in. long and 

 wide, 5-foliate, rather thick; dark green, glabrous and slightly shining 

 on the upper surface; lighter green but not yellowish, and glabrous 

 beneath. lA'aflets very broad, oblong-oval, taper-pointed, stalked, 

 outline entire; finely, sharply and mostly singly serrate-dentate; the 

 middle one broadest often nearly orbicular antl slightly coniate near 

 the petiolule; the side ones a little narrower, oblong-oval or rhom- 

 boidal, more narrowly rounded at the base; the basal ones similar 

 in shape but smaller and more narrowly rounded at the base. Petiole 

 and petiolules stout, strong, grooved; dark red on the upper side, 

 green-yellow beneath; glabrous; prickles strong and hooked con- 

 tinued on the midribs; the abundant secondary prickles and glandular 

 covering like that of the stem; the petiolule of the middle leaflet about 

 1 in. long, the side ones one-third as long, and the basal leaflets short 

 stalked but not sessile. 



Old canes. Stem faded, primary prickles intact, secondary ones 

 considerably impaired; in favorable places the old leaves often remjiin- 

 ing. New growth entirely of I'eafy horizontal fruit branches well
