Woods and hillsides, Canada ! and Hudson's Bay to Kentucky ! and to the 

 Rocky Mountains near the sources of the Platte, Nuttall. May-June. — 

 Leaves pubescent, particularly on the lower surface : petioles downy. Calvx 

 greenish-white, broader than the ovary. Fruit brownish when ripe. — This

5. R. oxyacanthoides (Linn.) : stems usually clothed with bristly prick- 

 les ; subaxillary spines 1-3, often united at the base ; leaves roundish, sub- 

 cordate, 5-lobed, pubescent or nearly glabrous, the lobes deei)ly toothed of 

 crenate ; peduncles very short, about 2-flowered ; calj^x-tube cyiindracecus, 

 pubescent at the base within ; the segments spreading, rather longer than the

On rocks, &c. Newfoundland ! and throughout Canada to the Saskatcha-

 or prickles, \vhich sometimes occur also on the petioles. Calyx greenish 

 tinged with purple. Fruit bluish-purple or reddish. — In the Hortus Upsal- 

 ensis, Linnfeus states this species to be a native of Virginia ; but in the Spe- 

 cies Plantarum it is said io come from Canada. We have never met with it 

 within the limits of the United States. 



6. R. liirtellum (Michx.) : stems prickly or naked ; subaxillary spines 

 usually solitary, and very short ; leaves roundish, cordate, 3-5-lobed, 

 toothed, pubescent beneath; peduncles very short, deflexed, 1-2-tlowered ; 

 calyx-tube campanulate, glabrous, hairy at the throat within ; the segments 

 twice the length of the petals, nearl}' equalling the stamens and 2-cleft hairy 

 style ; fruit smooth.— Michx. ! fl. 1. p. Ill ; Pursh, fl. 1. p. 1G3. R. sax-

 R. oxyacanthoides, but in the form of the calyx it is n)ore like R. Cynosbati. 

 The spines are sometimes wanting ; the leaves are quite small and more or 

 less pubescent. Flowers greenish-white tinged with purple. Fruit (red, 

 Michx.) bluish-purple.

 illary spines 1-3, very small and slender, subulate ; leaves roundish, 3-lobed, 

 incisely toothed, pubescent, as well as the slender petioles ; peduncles and 

 pedicels elongated, almost filiform, 1-2-fIowered, pubescent, as well as the 

 calyx and ovary ; segments of the calyx linear-ligulate, many times longer 

 than the very short tube, and about the length of the very hairy fila- 

 ments, at length recurved; petals lanceolate, minute ; anthers ovate-oblong; 

 style as long as the stamens, 2-cleft at the apex, very hairy below ; fruit
