 Kootauie Trail (Dawson). 



Tlie species was founded upon tlie resinous serrulate-toothed specimens col- 

 lected by Fendler, a form common in Colorado and New Mexico, but the more 

 widely distributed form is wholly without glandulosity. While closely approach- 

 ing the more finely tomentose and smoother forms of R. Calijornica, it appears to 

 be sufficiently differentiated from it by its more strictly globose fruit (the calyx 

 raised upon a less prominent neck or closely sessile), the pubescence never 

 villous, the receptacle and pedicel always glabrous and sepals never hispid, and 

 the foliage more or less glaucous. The leaves are usually narrower and cuneate 

 at base, never rounded or ovate. As a rule, and as in the other species of the 

 group, the sepals are entire. In a few vigorous specimens, however, from near 

 Salt Lake City, and from Klamath River, California, an occasional lobe is found 

 on the outer sepals. 



Specimens which may belong to a distinct species of this group have been 

 collected near Pembina (Ilavard), in the high mountains of Montana (Swallow), 

 and near Fort Colville, Washington Territory ( Watson), distinguished by nar- 

 rowly oblong fruit (8 to 10 lines long), on mostly solitary naked or hispid short 

 pedicels, the stems (4 inches to 4 feet high) with very slender straight spines. 

 A fuller series of specimens is needed.

 9. R. WooDsii, Lindl. Stems usually low (| to 3 feet liigb), with 

 slender straight or recurved sphies, and sometimes witli scattered 

 prickles, or unarmed above : stipules narrow or dilated, entire ; leaflets 

 5 or 7 (sometimes 9), obovate to oblong or lanceolate, rounded or 

 acute at the summit, obtuse or usually cuneate at base, glabrous or 

 subpubescent above, villous or finely pubescent or glabrous beneath 

 (with the rhachis and stipules), simply toothed often only above the 

 middle, somefinaes resinous and serrulate-toothed, sometimes glaucous, 

 usually small (the terminal A to Ih inches long): flowers (1^ to 2 

 inches broad) corymbose or very often solitary, on very short naked 

 pedicels : sepals naked or hispid, the lobes more or less conspicuous : 

 fruit globose with a short neck, 4 or 5 lines broad. — Monogr. Ros. 21,
