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 o'^long 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 :.'-3-lobed, creuately 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- ! 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. Un 

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



H. ovalifolla 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 sim^ple leaves and small yellowish green flowers solitary 

 in the~forks of dichotomous branches or terminal. Calyx rotate, 

 its short tiube coherent with the ovary, tbe 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 placentae 

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

 taceous testa. 



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

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

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

 branchjets : 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.
