sepals liis[)id or sometimes naked : fruit globose, with a very short 

 ueck, 4 or 6 lines long. — Proc. Amer. Acud. 8. 382. 



Had. Woods and stream-banks in Western Oregon and northward to Britisli 

 Columbia. — Oregon, Multnomah County {Hall, Engelmann, Howell, Henderson) ; 

 Washington Territory, Klickitat County {Suksclorf), Seattle {Engelmann, Sar- 

 gent) ; British Columbia, Vancouver Island {Kelloug). 



Katlier doubtfully distinguished from forms of R. Califomica by the somewhat 

 smaller and more globose fruit, and by the spines never recurved but very fre- 

 quently ascending. Specimens from Thompson River in British Columbia 

 (Macoun) may belong here, but are resinous. Wholly or nearly glabrous speci- 

 mens also, from the Scott Mountains, California {Greene), and from Siskiyou 

 County {Pringle), can hardly be separated from it, and another collected by the 

 Wilkes Expedition (" Cascade Mountains to the Columbia") would be referred 

 to it but for the somewhat recurved spines. 



7. R. Californica, Cham. & Schlecht. Stems often tall (1 to 8 

 feet high), with usually stout more or less recurved or sometimes 

 straight spines, frequently scattered, or wanting, often prickly : stipules 

 mostly narrow, usually naked, sometimes glandular-ciliate ; rhachis 

 pubescent or prickly; leaflets 3 to 7 (very rarely 9), round or broadly 

 elliptical to oblong-ovate or -obovate, most frequently obtuse at both 

 ends and sessile, slightly pubescent or glabrous above, villous or 

 tomentose beneath, and simply toothed, or often more or less resinous 

 and the teeth either entite or serrulate, very rarely wholly glabrous, 

 the terminal | to Ih inches long: flowers corymbose or sometimes 

 solitary (1 to 1^ inches broad), on slender usually short and naked (or 

 villous or sometimes hispid) pedicels ; sepals and receptacle glabrous 

 or villous or rarely hispid (the receptacle very rarely so) : fruit ovate- 

 globose, with a usually prominent neck, about 6 lines long by 4 broad.

H.\B. Along streams throughout California, in the valleys and Coast Ranges, 

 and in the Sierra Nevada to an altitude of 5-6,000 feet, in Western Nevada, 

 and northward to the Columbia, and probably to British Columbia. — Lower 

 California, near the boundary {Orcnlt) ; California, from numerous localities and 

 collectors [Coulter, Hartweg, Pickering, Wislizenus, Bridges, Bigelow, Parry, Heer- 

 mann, Dennison, Shellon, Torrey, Brewer, Bolander, Kellogg, Palmer, Hooker Sf Gray, 

 G. R. Vasey, Rolhrock, dmgdon. Parish, Engelmann, Sargent, Cleveland, Minr, Red- 

 field, Greene, etc.) ; Western Nevada (//. Engelmann, Watson, n. 349 in small part, 

 Wheelei-); Oregon, near Portland (Engelmann); Washington Territory {G. R. 

 Fase//), Klickitat County (Suksdorf) ; British Columbia, on Thompson River 

 (Macoun ?). 



An exceedingly variable species, in every respect, but it seems impossible to 

 divide it to any good purpose. The villous-pubescent form (var. Chamissoniana, 

 Meyer; var. pnhescens, Crepin) is the typical one, while the one witii resinous 

 pubescence and serrulate teeth (var. Petersiana, Cham.; var. glandnlosa, Crepin) 

 is as widely distributed and rather more frequent. The wholly glabrous form
