G. Inclsum Nutt. T. & G. Fl. i, 206. Densely pilose with short white 

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

 from 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 leaves, with a peduncle 

 in the axil 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 J4-2 inches long, 

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

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

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

 vate 6-8 lines long, more or less retuse, conspicuously veined, densely

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

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

 Columbia and Dakota. 



G. Oreganum. Pilose with short white deflexed hairs or that of the 

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

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

 mternodes, dichotomously branched : leaves all rather long petioled, deeply 

 6-7-cleft, the cuneate segments irregularly incised and toothed: flowers 

 bright purple on long slender ascending peduncles thus appearing loosely
