Very variable, and in some of its forms nearly approacliing R. Fcudleri. The 

 resinous-pubescent specimens are all from tlie Platte Valley in Colorado. In 

 tiie more eastern localities the pubescence is often quite villous. The specific 

 name was given in honor of Josi'i)h Woods, an English botanist, who, according 

 to Lindlcy, was the first to distinguish the species of roses by their true 

 characters. 



* * Receptacle densely prickly, and sepals pinnatifid. 



10. R. MiNUTiFOMA, Engelm. Stems rigidly much-branched, 2 to 

 4 feet high, armed with numerous at length stout spiues, usually terete 

 above the base, straight aud si:)reading or slightly recurved, and with 

 scattered deciduous prickles ; internodes of the branches very short : 

 stipules usually very short and narrow, glandular-ciliate ; leaflets 3 to 

 7, very small (the terminal 2 to 5 lines long), rounded to oblong- 

 lanceolate, very coarsely and unequally toothed and the margin revo- 

 lute, pubescent, less so above: flowers small (an inch broad), always 

 solitary, and the very short pubescent or somewhat prickly pedicel 

 bractless ; sepals densely pubescent and with few prickles, shortly aj)- 

 pendaged above, the outer pinnately lobed : fruit globose with a very 

 broad orifice, densely prickly, 3 or 4 lines broad. — Bull. Torr. Bot. 

 Club, 9. 97 and 127. 



Hab. Lower California; hillsides near the coast, between Sauzal and Ence- 

 nada on Todos Santos Bay {Jones, Orciitt, Parnj, Pringle). 



II. — Sepals spreading after flowering, deciduous. Infrastipular spines present 

 (or wanting above), and the stems often more or less covered with scat- 

 tered deciduous prickles. 



A. — Styles distinct, numerous, persistent. Base of the calyx persistent on the 

 globose fruit. Calyx, receptacle, and pedicel iiispid. Teeth simple and 

 pubescence not resinous, except in li. Mcx'uana. 



* Pedicels usually elongated. Eastern species, 

 -t- Leaflets finely many-toothed. 



11. R. Carolina, Linn. Stems usually tall (1 to 6 feet high), 

 with stout straight or usually more or less curved spines : stipules 

 long and very narrow, naked or glandular-ciliate; leaflets dull green,
