308 CONTEIBUTIONS FEOM THE NATIONAL HEKBARIUM. 



Dr. Greene was no doubt correct in his judgment that this should be separated 

 from R. stellata, from which it is farther separated than are most of the nearly related 

 species of the genus from each other. He has pointed out the differences very accu- 

 rately in his description. 



3. Rosa suflfulta Greene, Pittonia 4: 12. 1899. 



Type locality: Near Las Vegas, New Mexico. Type collected by G. R. Vasey, 

 June, 1881. 



Range : Northern and eastern New Mexico. 



New Mexico: Las Vegas; Ute Park; Raton Mountains; Sierra Grande; Santa Fe; 

 Perico Creek; White Mountains. Transition Zone. 



This is probably the same as R. pratincola Greene; the name suffuUa, however, 

 has priority. 



This is perhaps the stoutest of all the roses of the State, though it commonly does 

 not grow very tall. The young stems are stout, greenish, strictly erect, very spiny, 

 and veiy leafy. The leaves consist of 4 or 5 pairs of leaflets and a terminal one, all 

 elliptic and sharply serrate; they are rather thick, dull green, and somewhat pubes- 

 cent. The flowers are bright pink, about 5 or 6 cm. in diameter, and produced in 

 crowded corymbs. 



4. Rosasayi Schwein. Narr. Exp. St. Peter's Riv. 2: 388. 1824. 

 Type locality: Canada. 



Range : Quebec and Alberta to Michigan and northern New Mexico. 

 New Mexico: Johnsons Mesa {Wooton). 



5. Rosa adenosepala Woot. & Standi. Contr. U. S. Nat. Herb. 16: 131. 1913. 

 Type locality: Along the Pecos River 8 miles east of Glorieta, New Mexico. 



Type collected by Heller (no. 3674). 



Range: Known only from type locality. 



Readily distinguished from our other species by the densely glandular-bristly 

 calyx lobes. 



This is probably a plant of the Transition Zone. Although the region along the 

 Pecos in this locality supports a characteristic Upper Sonoran vegetation, the low 

 land bordering the river, as the result of the greater amount of moisture with which 

 it is supplied, is covered with plants common in the Transition Zone. 



6. Rosa hypoleuca Woot. & Standi. Contr. U. S. Nat. Herb. 16: 131. 1913. 



Type locality: Near Kingston, Sierra County, New Mexico. Type collected by 

 Metcalfe (no. 940). 



Range: New Mexico. 



New Mexico: Near Kingston; Winsor Creek. Mountains, in the Transition Zone. 



Related to Rosafendleri, but differing in having glabrous leaflets which are glaucous 

 underneath. 



7. Rosa melina Greene, Pittonia 4: 10. 1899. 



Type locality: Cerro Summit, aboA'e Cimarron, Colorado. 

 Range: Wyoming to northern New Mexico. 

 New Mexico: Santa Fe (Wootori). 



8. Rosa fendleri Crep. Bull. Soc. Bot. Belg. 15: 91. 1876. 



Type locality: New Mexico. Type collected by Fendler (no. 210). 



Range: Montana and South Dakota to Arizona and New Mexico. 



New Mexico: Chama; Santa F*^ and Las Vegas mountains; Sandia Mountains; 

 Raton; Sierra Grande; Carrizo Mountains; Tunitcha Mountains; Copper Canyon; 

 Fort Bayard; White Mountains. Transition Zone. 



Probably this is the most common rose of the State, occuring at middle elevations 

 in the mountains. It is usually a slender branching bush about 1 meter high with
