8o THE SMALL FRUITS OF NEW YORK 



weak prickles. Petioles glabrous, petioMes pubescent, both beset with scattered, hooked 

 prickles; stipules linear-lanceolate. Leaflets 3-5, the lowest sessile, obliquely ovate, acutish 

 at both ends; the lateral ones stalked, broader, ovate, abruptly pointed, roundish at the 

 base; the terminal leaflet cordate-ovate, suddenly contracted into a prolonged point; 

 in 3-foliolate leaves the lateral leaflets broad and large with a lower lobe; rather firm in 

 texture, glabrous and dark green above, slightly paler green and velvety pubescent under- 

 neath ; doubly serrately toothed, teeth rather large and broad, mucronate, like in R. frondo- 

 sus. Flowering branches pubescent, sparingly prickly; lower leaves 3-foliolate, with 

 obovate-cuneate, obtuse leaflets ; the upper ones simple, the lower ones broadly lanceolate, 

 the uppermost narrowly lanceolate, pointed at the base and long acuminate, with large 

 simple or double teeth, all velvety pubescent underneath. Flowers not very numerous, in 

 a leafy, pubescent or villous corymb; pedicels slender, occasionally prickly; calyx pubes- 

 cent, lobes ovate, cuspidate, white tomentose inside; petals 12-15 nini long, elliptic, white. 

 Fruit elongate, 10-15 nim long, black, sweet. 



Northeastern United States; from Maine to northern New York. 

 Differs from R. frondosus chiefly in less roundish leaves and in the upper 

 leafy bracts being more pointed and deeper serrate. 



R. jeckylanus, Blanchard Rhodora 8:177. 1906, is considered by 

 most writers as a synonym of R. reciirvans. Blanchard's specimens seem 

 to represent intermediate forms connecting in some way R. frondosus 

 and R. recurvans; they have, however, a more villous inflorescence than both, 

 the bract leaves of the former, and the leaves of the turions of the latter. 



R. recurvans and a plant grown as R. jeckylanus were both crossed with 

 Erskine Park (blackberry), and also with Snyder at Geneva. 



Rubus arundelanus. Blanchard i?/jodora 8: 176. 1906. 



Canes angular when yovmg, terete when old, with rather numerous and slender, straight, 

 retrorse prickles from a broader base. Petioles slightly pubescent, the petiolules villous, 

 both beset with numerous small hooked prickles; stipules linear or subulate-lanceolate. 

 Leaves 5-foliolate, rather thin and light green on both sides, with scattered single hairs or 

 glabrescent above, softly pubescent beneath, sharply and unequally doubly toothed, 

 the teeth narrow and sharp; lower leaflets sessile, obliquely lanceolate or oblanceolate, 

 acuminate, attenuate at the base; lateral leaflets longer stalked, larger and broader, sub- 

 cordate at the base and suddenly contracted into a long point; terminal leaflet very long 

 stalked, usually subcordate, ovate, long pointed, lobately doubly toothed, in the upper 

 half, sometimes broader and ovate-deltoid, 7-10 cm long and 5-6 cm wide. Flowering 

 branches pubescent, sparingly prickly ; the leaves with scattered hairs above and pubescent 

 at the back, extremely variable, mostly 3-foliolate, but often the lateral ones deeply lobate 

 and thus seemingly 5-foliolate, sometimes also the terminal leaflet deeply 3-lobed; leaflets 

 of the lower leaves usually more rounded, those of the upper ones much narrower, all 

 attenuate at the base and deeply, often lobately doubly toothed; the uppermost leaves or 

 leafy bracts narrowly lanceolate, acuminate. Flowers about 6-8, in a short corymb with
