106 GERANIACE. GERANIUM, 
inches to a 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, 
transversely rugose: seeds minutely striate. Plentiful northward, from 
northwestern California to Brit. Columbia. 
+ + + fepals not awned: carpels rugose, not hairy, at maturity 
remaining on the axis, not borne on the recurved style. 
G. pusittum L. Sp. ed. 2, 957. Soft-pubescent or the pedicels and 
calyx villous and usually glandular: stemsslender 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; cauline 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 Pl. Fendl. 26. Rather stout, more or less 
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. 
G. Richardsoni F. & M. Ind. Sem. Petr. iv, 37. Erect with slender 
branches 114-3 feet high: pubescence usually fine and appressed: leaves 
deeply 5-7-cleft, lobes sharply incised : pedicels and sepals glandular pilose : 
tals entire, hirsute at base. In the mountains from Brit. Am. to New 
exico and westward, perhaps on our eastern border. 
G. incisum 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 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 eeply 2-lobed, the oblong 
lobes coarsely incised and serrate; the upper ones similar but very short 
petioled or sessile :flowers purple, on slender pedicels 4-2 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 
bearded at base ; filaments about equalling the style, dilated and ciliate at 
base ; ae minutely hispid, the free tips 1-2 lines long and spreading or 
recurved. 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 spreading and gland-tipped, stems several from the crown of a 
thick perennial root, erect, 1-2 feet high comparatively slender with long 
internodes, dichotomously branched: leaves all rather long petioled, deeply 
5-7-cleft, the cuneate segments irregularly incised and toothed: flowers 
bright purple on long slender ascending peduncles thus appearing loosely 
flowered, pedicels 1-2 inches long slender: sepals oblong-ovate, outer ones
