7. RuBus HisPiDus, Linn. Running Swamp Blackberry. 



Stems slender, prostrate, somewhat shrubby, clothed with retrorse bristles or weak prickles; 

 leaves mostly trifoliolate, somewhat persistent ; leaflets rather coriaceous, obovate, commonly 

 obtuse, unequally serrate, smooth and shining ; stipules linear ; peduncles naked, corymbosely 

 several-flowered ; pedicels filiform ; flowers small ; petals obovate, twice as long as the 

 spreading acute sepals ; fruit small, black. — Linn. sp. 1. p. 493 (not of DC); Torr. ^ Gr.

var. setosus : stems reclining ; leaflets oblong-obovate, narrowed at the base ; branchlets 

 and pedicels bristly. Torr. ^ Gr. I. c. R. setosus, Bigel. I. c. ; DC. I c. 



Stem 2-3 feet or more in length, trailing and throwing up short flowering branches, more 

 or less hispid (often very much so) with slightly curved reversed bristles, which finally harden 

 so as to be somewhat pungent. Flowering branches 4-8 inches high. Leaves rarely 5- 

 foliolate, on long slender petioles which are usually hispid like the stem : leaflets 1 - iJ^ inch 

 long, all of them on distinct footstalks, sometimes rather acute. Peduncles 3 - 5-flowered, 

 in a more or less open corymb which is often leafy ; sometimes 2 or 3 pedicels in the axils of 

 the lower leaves. Flowers about half an inch in diameter. Sepals ovate-oblong, acute, but 

 scarcely appendiculate. Petals white. Fruit usually consisting of a few large grains, and 

 sour, but sweet when it grows in exposed situations. 



Swamps and wet woods ; sometimes in rather dry, but shady situations. Fl. June. Fr. 

 August. In swamps the leaves are generally persistent through the winter. 



8. RuBUS cuNEiFOLius, PursJi. Sand Blackberry. 



Shrubby, low, and armed with stout recurved prickles ; stems mostly erect, terete ; young 

 branches and under surface of the trifoliolate leaves pubescent-tomentose ; leaflets cuneiform- 

 obovate, rather coriaceous, with the veins prominent underneath, serrate above the middle, 

 entire and slightly revolute near the base ; stipules lanceolate ; peduncles 2 - 4-flowered ; 

 petals oblong-obovate, twice as long as the woolly mucronate sepals ; fruit ovoid, black. —

 folius, Walt. fl. Car. p. 149, not oi Linn. 



Stem 1-3 feet high, much branched. Leaflets 1-2 inches long, all sessile, dark green 

 above, whitish and pubescent underneath, rather obtuse, or with a very short abrupt acumina- 

 tion. Flowers at the extremity of the branches ; the lower pedicels elongated and axillary. 

 Petals nearly as large as in R. villosus. Fruit large, black, abundant and well flavored. 



Sandy fields. Fl. May - July. Fr. July - August. I think this species grows in Suffolk 

 county, Jjong Island. It is abundant in New-Jersey ; certainly within a few miles of New- 

 York.
