cylindrical, 2-4 inches long, the subsessile branches subtended-by lanceolate 
ciliate bracts 6 lines long; calyx campanulate, 4 lines long, the somewhat 
unequal narrowly oblong lobes longer than the tube; petals filiform rudi- 
ments or none; stamens shorter than the calyx-lobes; filaments a line 
long; styles very short: capsule ovate, the acuminate beaks slightly 
exserted at maturity: seeds hispid. On gravelly plains at low elevations, 
Brit. Columbia to California. 
H. glabella T. & G. Fl.i, 581.(?) Glabrous or the upper part of the 
stem and inflorescence pulverulent-pubescent: stems wholly naked, rather 
slender, 1-2 feet high: leaves round-cordate, 1-3 inches in diameter pri- 
marily 5-lobed. the lobes often again 2-3-lobed, crenately toothed, the broad 
teeth bristly apiculate and ciliate, somewhat coriaceous, very glabrous 
both sides, persistent, on slender petioles 3-6 inches long; stipules con- 
spicuous, the free portion broadly subulate, long acuminate, ciliate: flow- 
ers rather small, numerous, in a rather loose spike-like panicle, 3-4 inches 
long, the sabsessile branches subtended by setaceous pectinately ciliate 
bristly acuminate bracts; calyx campanulate, 2-3 lines long, cleft to the 
middle, with somewhat unequal oblong obtuse lobes; petals white, shorter 
than the calyx-lobes, the lanceolate blade but little longer than the slender 
claw ; anthers subsessile: styles short, stout: mature capsulenot seen. On 
rocks along the Columbia river between the Cascades and The Dalles. 
H. ovalifolia T. & G.1. c. Minutely and somewhat glandularly 
 pderonncN throughout: somewhat cespitose stems leafless, 4-12 inches high: 
eaves ovate, subcordate to somewhat cuneate at base, incisely 5-lobed, the 
lobes coarsely toothed with obtuse to acute bristly apiculate ciliate teeth, 
6-12 lines long, on petioles 1-2 inches long. persistent; stipules ‘narrow, 
acute, ciliate: flowers rather few, in an almost or quite simple spike; bracts 
lanceolate; long acuminate, laciniate and ciliate above the middle ; calyx 
tubular, becoming ureceolate, 3 lines long cleft to the middle, the lanceolate 
mostly acutish lobes white and petal-like; petals usually if not always 
wanting; filaments subulate, a line long: capsule obovoid, cleft nearly tothe 
base, the acuminate beaks scarcely equalling the calyx: seeds somewhat 
reniform, hispid. On cliffs and dry rocky ridges, throughout eastern Ore- 
gon and Washington. 
16 CHRYSOSPLENIUM Tourn. L. Gen. n. 320. 
Small depressed herbs growing in swamps and brooks with 
fleshy simple leaves and small yellowish green flowers solitary 
in the forks of dichotomous branches or terminal. Calyx rotate, 
its short tube coherent with the ovary, the 4-5 obtuse lobes col- 
ored within. Petals none. Stamens twice as many as the calyx- 
lobes, inserted on the margin of the evident epigynous disk: 
anthers reniform, 2-celled. Styles 2, distinct: stigmas simple. 
Capsule obcordate, compressed, 1-celled with 2 parietal placentz 
at the base, 2-valved at the summit, seeds numerous, with a crus- 
taceous testa. 
C. glechomefolia Nutt T. & G. Fl. i, 589. Glabrous: stemsascending, 
2-6 inches high: leaves opposite, roundish, abruptly cuneiform at base, cre- 
nate above,2-6 lines broad: flowers usually solitary, in the forks of the upper 
branchlets : calyx 2 lines broad with rounded entire lobes; stamens about 
equalling the calyx: capsule at length exserted. About springs and in 
marshes, brit. Columbia to California west of the Cascade mountains.
