MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. 225 



This is recognized by its large flowers, stout spines, doubly serrate 

 firm leaves and large fruit. It nearly always grows in open woods, 

 at an altitude of 1000-2500 m.

 Nearest related to R. JVutkaim, but the fruit is somewhat smaller, 

 the peduncle densely bristly and the infrastipular spines much 

 smaller and more like those of the next species.

It is evident that what Watson and Couher regarded as R. Fendleri 

 is the true Rosa Woods?'/'. If R. Fendleri Crepin is distinct, it is a 

 species of the Southwest and not found in Montana. Watson's char- 

 acter for R. Woodsii, " outer sepals laterally lobed," fails, as this oc- 

 curs occasionally in all the roses of the Cinnamomiae group. Lind- 

 ley in the original description of R. Woodsii states that they are entire. 

 In western Nebraska there is a form of R. Woodsii, or a related spe- 

 cies, with larger yellow fruit and more pubescent leaves, which I for- 

 merly regarded as R. Woodsii, but a comparison with Lindley's de- 

 scription and plate has persuaded me that the form with small red fruit 

 and nearly glabrate leaves is the true R. Woodsii. The form with 

 larger yellow fruit, if distinct, should bear the name R. Maximiliam 

 Nees. Watson's R. Woodsii probably comprises forms of both, as 

 well as of some of the other Cinnainontiae. Rosa Woodsii grows 

 along streams, up to an altitude of 2000 m.
