In "dry places and also along the margin of swamps, Newfoundland and 

 New Enirland States ! to Georgia ! y. Western States from Ohio ! to Lou- 

 isiana! Arkansas! and Alabama! May-.Tune. — .Stem 1-2 (or sometimes 

 3) feet high, with greenish branches ; the sti|)ular prickles straight and slen- 

 der, horizontal or deflexed, sometimes a little recurved. Flowers rather 

 large, pale red. — We have various intermediate forms of this common 

 and widely diffused Rose, which, we are confident, belong to a single 

 species. 



4. R. nitida (Willd.) : stems low, and, with the branches and pedtmcles, 

 densely armed wnth straight and slender prickles or strong bristles; leaflets 

 5-9, rather rigid or coriaceous, very glabrous and shining, lanceolate or lan- 

 ceolate-oblong, serrate ; stipules dilated, reaching to the lowest pair of leaf- 

 lets ; flowerssolitary ; calyx hispid, witli the bristles somewhat glandular ; 

 petals (red) obcordate ; fruit (scarlet) shining, globose. — Willd. enum. \. p.

Newfoundland ! to Massachusetts, Mr. Oakes ! — Resembles some forms 

 of R. lucida, but appears to be an entirely distinct species. The specimen 

 named R. nitida in Willdcnow's herbarium is R. laevigata, Michx. .' 



5. R. cinnamomea (Linn.) : prickles of the young sterile stems crowded, 

 straight, and unequal, the larger ones subulate, the smaller setaceous and 

 not glandular; those of the branches stouter, stipular, and arcuate; leaflets 

 5-7, oval-oblong, simply serrate, cinereous-pubescent beneath ; stipules of 

 the sterile branches linear-oblong, ^vith the margins tubulose-connivent ; those 

 of tlie flowering branches dilated above, with ovate acuminate spreading 

 auricles ; segments of the calyx as long as the corolla, entire, lanceolate- 

 acuminate ; peduncles short, straight in fruit, and, as well as the calyx-tube, 

 glabrous; fruit globose, smooth, pulpy, crowded with tlie connivent persistent 

 calyx-segments. Koch.— Engl. hot. t. 2388; Lindl. Ros. p. 28, t. 5 ; DC

Shores of the Oregon, Dr. Scolder, (ex Borrcr in Hook. I. c.) p. From 

 the Saskatchawan to Mackenzie River, Dr. Richardson. — We have a spe- 

 cimen from Dr. Scouler, labelled R. cinnamomea, which appears to be R. 

 fraxinifolia. We have no wild spechiiens of R. majalis; but a cultivated 

 one from, the garden of the London Horticultural Society has wholly the 

 dilated stipules of R. cinnamomea. 



6. R. blanda (Ait.) : stems and sterile branches (reddish) armed with 

 scattered unequal straight and slender deciduous prickles, the flowering 

 branches and petioles "mostly naked ; leaflets 5-7, oval or oblong, obtuse, 

 equally serrate, not shining above, pale and usually minutely pubescent 

 beneath, the petioles tomentose-pubescent or sometimes glabrous ; stipules 

 much dilated, with entire or glandular-serrulate margins ; flowers 1-3, on
