inches toa foot long, the herbage softly and somewhat clammily villous : 

 leaves an inch broad or more, cleft into oblong obtusish lobes: sepals ovate- 

 oblong, not awn-pointed : petals very small, rose-color : carpels glabrous, 

 t i;ti i sversely rugose : seeds minutely striate. Plentiful northward, from 

 northwestern California to Brit. Columbia. 



+_ h_ +. Sepals not awned: carpels rugose, not hairy, at maturity 

 remaining on the axis, not borne on the recurved style. 



(r. pusillum L. Sp. ed. 2, 957. Soft-pubescent or the pedicels and 



calyx villous and usually glandular: stems slender or ascending, 3-6 inches 

 long: lower leaves orbicular an inch or less in diameter equally cleft into 

 7-9 linear or oblong lobes, each more or less regularly 3-toothed at the 

 apex ; eauline round-reniform, 5-7-parted, the ^divisions cleft into linear 

 lobes: peduncles often in the axils of bracts opposite the leaves, short : 

 sepals ovate, acute or acuminate not awned: petals pale purple, about 

 equalling the calyx, usually only 5 of the filaments antheriferous : carpels 

 fine canescent, keeled, not wrinkled: seeds smooth. Common in open 

 places throughout the Willamette valley; introduced from Europe. 



** Perennials: flowers large : stems naked below, dichotomously 

 branched with opposite leaves above: sepals shortly aristate, scarious 

 on one side, the scarious portion often extending lobe-like beyond the 

 apex : filaments and petals pilose at base. 



G. Fremonti Torr, in Gray PI. Fendl. 26. Rather stout, more or les< 

 pubescent throughout with a close glandular pubescence, sparsely inter- 

 mixed with longer pilose hairs: radical leaves 7-cleft, the segments 3-lobed 

 or incised ; cauline 3-5 cleft, the divisions 3-lobed : petals obovate twice 

 the length of the sepals : villous at base. Dry open hillsides, Idaho to the 

 Rocky Mountains. 



(*. Ric hards on i F. & M. Ind. Hem. Petr. iv, 37. Erect with slender 

 branches 1^-3 feet high : pubescence usually fine and appressed : leaves 

 deeply 5-7-cleft, lobes sharply incised : pedicels and sepals glandular pilose : 

 petals entire, hirsute at base. In the mountains from Brit. Am. to New 

 Mexico and westward, perhaps on our eastern border. 



9t> incisum Nutt. T. & G. Fl. i, 206. Densely pilose with short white 

 spreading or deflexed hairs to nearly glabrale : stems stout, numerous 

 Erom the crown of a large somewhat woody perennial root, 1-3 feet high, 

 dichotomously branched above with a long' 2-flowered peduncle or branch 

 in the forks or at length a pair of opposite sessile leates, with a peduncle 

 in theaxil of each, appearing compact and many-flowered : lower leaves very 

 long petioled, ample, round-reniform in outline, primarily deeply 3-lobed 

 or-parted, the broad cuneiform lateral segments deeply 2-lobed, the oblong 

 lobes coarsely incised and serrate; the upper ones similar but very short 

 petioled or sessile :flowers purple, on slender pedicels l o-2 inches long, 

 somewhat abruptly contracted above to the rather stout awn, outer one 

 somewhat pubescent and more or less glandular-eiliate ; inner ones min- 

 utely pubescent, with rather broad scarious margins ; petals broadly obo- 

 vate (!-S Hues long, more or less retuse, conspicuously veined, densely 

 bearded a1 base; filaments about equalling the style, dilated and ciliate at 

 base ; styles minutely hispid, the tree tips 1-2 lines long and spreading or 

 recurved. Along small streams, eastern Oregon and Washington to Brit. 

 ( lolumbia and 1 Dakota. 



Ct< Oreganum. Pilose with Bhort white deflexed hairs or that of the 

 pedicels spreading and gland-tipped, stems several from the crown of a 

 thick perennial root, erect. 1-2 feel high comparatively slender with long 

 inter nodes, dichotomously branched: leaves all rather long petioled. deeply 

 5-7-cleft, the cuneate segments irregularly Incised and toothed: dowers 

 bright purple on long slender ascending peduncles thus appearing loosely 

 flowered, pedicels 1-2 inches long slender: sepals oblong-ovate, outer ones
