S. Carolina ! to Louisiana ! cultivated in gardens and extensively 

 naturalized. April. — Stem with long flexible branches, capable of being 

 trained to a great length. Flowers very large, white. — This evergreen 

 species has been cultivated for many years in the Southern States, under 

 the name of Cherokee Rose. It is doubtless of Chinese origin ; but as it is 

 not the R. Sinica of Linnaeus, we continue to use the name of Michaux, 

 which is several years older than the second edition of the Hortus Kewensis. 

 According to Elliott it is well adapted for hedges. It is certainly too tender 

 to endure the winter of the Northern States ; hence the plant from Lake 

 Huron referred to tliis species by Mr. Borrer, in Hooker's Flora, must be 

 very different. 



14. R. bracteata (Wendl.) : branches erect, tomentose, amied wiih strong 

 recurved often geminate prickles ; leaflets 5-9, obovate, slightly serrate, cori- 

 aceous, shining, glabrous ; stipules nearly free, setaceous, fimbriate ; flowers 

 solitary, terminal, on short peduncles ; bracts large, surrounding the base of 

 the calyx ; peduncles and calyx densely tomentose ; fruit globose, large, 

 orange-red. Seringe. — " Wendl. obs. hort. Herrenhaus. p. 7, t. 22 ;" Re- 

 dout. Ros. 1. i. 35 ; Seringe, in DC. prodr. 2. p. 602. 



Naturalized in hedges near New Orleans, Dr. Riddell ! — Flowers large, 

 white. This species is also of Chinese origin.

15. R. lutescens (Pursh) : fruit globose and, with the peduncles, glabrous; 

 branchlets hispid-prickly ; leaflets 7, oval, serrate with acuminate teeth, gla- 

 brous ; petioles unarmed ; flowers solitary ; segments of the calyx lanceolate, 

 cuspidate ; petals oval, very obtuse. Pursh, Ji. 2. p. 736 ; Lindl. Ros. p. 47, 

 t.9. 



Described by Pursh from a garden specimen said to come from Carolina. 

 Flowers white with a faint tint of yellow. Pursh. Fruit black, crowned with 

 the connivent sepals ; peduncle thickened at the apex. Lindl. — Probably 

 not American. 



R. Californica (Cham. & Schlecht. in Linnaa, 2. p. 35.) — Under this name a 

 supposed new species is indicated but not characterized, the specimen being in- 

 sufficient. The branches are said to be glabrous, with slightly recurved stipular 

 prickles, otherwise unarmed : the leaflets 5-7, ovate, obtuse, sharply serrate, to. 

 mentose beneath, pubescent above, not glandular, the terminal one largest, about 

 9 lines in length : the flowers somewhat corymbose, about the size of those of R. 

 pimpinellifolia : the peduncles furnished with spreading hairs : the calyx-tube 

 ovoid, glabrous ; the segments ovate, with a long dilated spatulate acumination, 

 &c. St. Francisco, California. 



The following North American species of Rosa are proposed by Rafinesque in 

 his monograph (published in Ann. sci. phys. Par., and afterwards in a separate 

 form), viz : R. Kentuckensis, trifoliolata, elegans, globosa, cursor, ohovata, 

 nivea (R. Rafinesquii, Seringe), pusilla, enneaphylla, Jiezuosa, acuminata, pra. 

 tensis, riparia, and dasistema.
