PA NASSIA 



5-7-lobed,the lobes obtuse, crenate with mucronate teeth : panicle spike-like, 

 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 beats 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 subsessile branches subtended by setaceous pectinately ciliate 

 bristly acuminate bracts; calyx campanulate,. 2- 5 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 capsule not seen. On 

 rocks along the Columbia river between the Cascades and The Dalles. 



H. ovalifolia T. & G. 1. c. Minutely and somewhat glandularly 

 pubescent throughout : somewhat cespitose stems leafless, 4-12 inches high: 

 leaves 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 urceolate, 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 to the 

 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- 

 lohes, 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 placentae 

 at the base, 2-valved at the summit, seeds numerous, with a erus- 

 taceous testa. 



C. glecliomsefolia Nutt T. & G. Fl. i, 589. Glabrous: stems ascending, 

 2-6 inches high: leaves opposite, roundish, abruptly cuneiform at base, i-re- 

 nate above, 2-6 lines broad: flowers usually solitary, in the forks of the upper 

 branchiets : 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.
