7 GEUM L. Gen. n. 636. 
- Perennial herbs with mostly radical lyrate or pinnate leaves, 
adnate stipules and solitary or corymbose flowers. Calyx ob- 
conic at base, deeply 5-cleft, usually with 5 bracteoles alternat- 
ing with the lobes. Petals 5, obtuse or emarginate. Stamens 
numerous, inserted into the disk that lines the base of the calyx ; 
filaments somewhat persistent. Carpels numerous, 1-ovuled, on 
a dry, conical or clavate receptacle, becoming achenes; styles 
terminal, at least the base persistent, straight, or geniculate near 
the middle: stigma simple. Seed erect; radicle inferior. 
$1 Eveeum T. & G. Fl. i, 420. Flowers erect: segments of 
the calyx reflexed: head of carpels sessile: styles articulated 
and geniculate above the middle, the lower portion glabrous, 
hooked at the apex, persistent after the deflexed and mostly 
hairy terminal portion falls away. 
G. macrophyllum Willd. Enum. i, 557. Hirsute throughout with 
spreading yellowish hairs: stems mostly solitary, 1-3 feet high, usually 
simple: stipules foliaceous, ovate, lacerate serrate, adnate to the petiole 
below the middle, acuminate above; radical leaves lyrate and interruptedly 
pinnate, 6-12 inches long or more the terminal leaflet very large, 
round-cordate, irregularly lobed and toothed, the others very unequal, often 
very small; cauline leaves similar but with a short rachis or reduced to 
the terminal leaflet only: flowers yellow, 6-9 lines broad, in an open 
panicle; bractlets small, often wanting; lobes of the calyx ovate, long 
acuminate, puberulent or nearly smooth reflexed, ahout equalling the 
obovate or oblong p2tals: style three lines long, at length reflexed; achenes 
hispid, upon a nearly naked oblong receptacle. In moist meadows and 
along streams. Alaska to California and across the continent. 
G. strictum Ait. Hort. Kewii, 218. Stems and petioles hirsute or 
hispid, with spreading hairs: stems stout, 2-3 feet high. simple, dichoto- 
mous at the summit: radical leaves interrupted and somewhat lyrately 
pinnate; leaflets cuneiform-obovate, incisely lobed and serrate; cauline 
leaves 3-5-foliolate; the ‘eaflets rhombic-ovate or oblong, acute, sharply 
toothed and incised; appressed-pubescent; stipules large, incised: flowers 
rather large, numerous; bractlets shorter than the calyx-lobes; petals 
yellow, roundish-oval, longer than the calyx: carpels hispid at the apex; 
style glabrous, the upper joint hairy: receptacle densely pubescent. In 
fisids and moist places, Idaho to the New England States and Canada. 
§ 2. Sreversta Willd. Berl. Mag. v, 398 as genus. Flowers 
rather large, erect; segments of the calyx erect or spreading: 
head of carpels sessile: style wholly persistent. 
G. triflorum Pursh Fl. 736. Villous and hirsute: stems clustered, 
from stout branching rootstocks, 6-15 inches high, simple, nearly naked: 
radical leaves pinnate, with numerous cuneate-oblong irregularly incised 
leaflets: the cauline reduced to a few small linear-lobed leaves or bracts: 
flowers few, usually 3, on long peduncles; calyx often purplish, the linear 
bractlets 4-9 lines long usually exceeding the calyx-lobes and equalling 
the oblong purplish erect petals: tails of the smali achenes plumose, at 
length 2-3 inches long: receptacle small; hemispherical. On bleak hill- 
tops, from Arctic America to California and the Rocky Mountains.
