Klamath, Rattan, and adjacent Oregon, in Josephine Co., Howell; 

 the latter a transition toward the typical R. occidentalis. 



2. Broad-hook-styled, i. e. the recurved uncinate styles shorter than 

 the ovary, broad and flat, stigmatose for most of their length, 

 wholly persistent in a very sti-ong and flat triangular or gladiate 

 and hooked or curved beak which is much shorter than the flat 

 akene : and confluent with its sharp margin : radical leaves divided 

 or nearly so : petals only 5. 



R. ACUiFORMis. A foot high, strict, with pubescence in good part 

 appressed : leaves all palmately or pedately and deeply 3-5-parted or 

 even divided, and often again 2-3-cleft into nan-ower lanceolate or 

 linear segments and lobes : petals orbicular-obovate, one fourth inch 

 long, hardly double the length of the spreading calyx : akenes over 

 a hne long; beak of half their length. — R. acris, Hook. Fl. i. 18, 

 partly, & Lond. Jour. Bot. vi, 66, not L. — Northern Rocky Moun- 

 tains, lat. 58°, Drummond. Wyoming, Parry (distrib. as R. ajjinis). 

 Wind River, Dr. Forwood, and near Cheyenne, Greene. 



R. CANDS, Benth. Erect and robust, soon declining, densely soft- 

 villous with white hairs when young, becoming greener and sparsely 

 villous or glabrate : leaves or most of them 3-divided, and the middle 

 or all three leaflets petiolulate, commonly cuneate and 2-3-cleft, with 

 the lobes incised ; petals obovate, half-inch or less in length, fully 

 double the length of the soft-villous reflexed calyx: akenes 2| to 3 

 lines long, the very broad beak less than a line long, forming part of 

 the margin. — PI. Hartw. 295. R. Culiforniciis, var. canus, Brewer & 

 Watson, Bot. Calif, i. 8. R. occidentalis, var., Gray, Pi'oc. Am. Acad, 

 viii. 374. — Low ground in the valley of the Sacramento, Hartweg, in 

 flower only, but the hooked styles discerned by Bentham. Near Chico, 

 Mrs. Bidwell, specimens just received in flower and fruit, from the dis- 

 trict where Hartweg found it, enabling the completion of the character. 

 There are other specimens from the region, in blossom only, which 

 may belong to this species. The name is appropriate only to Hart- 

 weg's specimens ; the white and soft pubescence being conspicuous only 

 on the early growth. 



3. Short-styled; the introrsely stigmatic styles thickish-subulate and 

 mostly all persisting in the short (straight or recurved or even 

 hooked) beak : herbage hirsute or pubescent. 



o Lax or weak-stemmed, Californian : no stolons : petals (rarely 5 ?) 

 6 to 15 : beak of akenes stout-subulate, more or less hooked. 

 R. Californicus, Benth. R. dissectus, Hook. & Arn. R. del-
