In shady swamps and wet woods, Canada ! and Northern States ! to the 

 mountains of S. Carolina ! May-June. — Stem extensively prostrate among 

 mosses &c., with short erect branches, thickly clothed with strong bristles, a 

 few of which at length become i)rickles and are more persistent : the petioles 

 and peduncles are commonly more or less armed with tlie same rigid bris- 

 tles. The leaves are persistent until after those of the succeeding year are 

 j)roduced. Fruit sour, composed of few large grains. — We have specimens 

 from Mr. Oakes which are quite intermediate between the ordinary forms of 

 this species, and the R. setosus of Bigelow. 



20. R. trivialis (Michx.) : sarmentose-procumbent, shrubby, armed with 

 bristles and strong at length uncinate prickles ; leaves (persistent) 3- (or pe- 

 dately 5-) foliolate ; leaflets ovate-oblong or almost lanceolate, acute (rare- 

 ly obtuse and slightly obovate,) sharply serrate, nearly glabrous ; stipules 

 subulate ; peduncles 1-3-flowered ; flowers large ; petals broadly obovate, 

 more than twice the length of the reflexed sepals; fruit large, black.

Pennsylvania ? S. Carolina ! to Florida ! Louisiana ! Arkansas ! and 

 Texas ! in dry soil. March-May. — The leaves are more coriaceous and 

 often smaller than in any other N. American species, the young stems very 

 hispid as well as prickly, the flowers large in proportion, on long hispid or 

 prickly peduncles. It is very different from the Dew-berry of the Northern 

 States, which has been called R. trivialis. It ripens its fruit in May, and is 

 called Low Bush-Blackberry. 



21. R. cuneifolius (Pursh) : shrubby, low, armed with stout recurved 

 prickles ; stems mostly erect ; young branches and lower surface of the 3-foli- 

 olate leaves pubescent-tomentose ; leaflets cuneiform-obovate, rather coria- 

 ceous, with the veins prominent beneath, serrate towards the apex, the mar- 

 gin revolute near the base ; stipules linear-setaceous ; peduncles few-flow- 

 ered ; petals obovate (white or rose-color), much longer than the tomentose 

 oblong mucronate sepals ; fruit ovoid, black. — Pursh ! fi. 1. p. 347 ; Nutt. !

Sandy woods and fields, Long Island ! and New Jersey ! to Florida ! 

 May-June. — Stem 1-3 feet high. Leaves rarely pedately 5-foliolate : the 

 terminal leaflet petlolulate. Pedicels diverging. Fruit about half an inch 

 long, ripening in June in the Southern States (farther north in July and Au- 

 gust), juicy and well-flavored. 



22. R. ursinus (Cham. & Schlecht.) : stem procumbent, terete, aculeate; 

 branches, petioles, midrib of the leaflets, and calyx prickly and tomentose ; 

 leaves 3-foliolate (the uppermost often simple) ; the leaflets broadly ovate, 

 somewhat petiolulate ; the terminal one subcordate, somewhat lobed, unequal- 

 ly serrate, hirsute above, tomentose beneath ; stipules linear, small ; pedun-
