EPILOBIUM. 



few, nodding ; petals 2-4 lines long, violet; capsules 20-30 lines long, their slen- 

 der peduncles about half as long: seeds finely papillate; coma dingy. 

 Union county, Oregon (Cusick). 



E. glandulosum Lehm. Hook. Fl. i, 206. Tall and rather thick 

 stemmed, the largest specimens branched ; commonly somewhat loosely 

 crisp-pubescent above or with very flexuous glandular hair- : leaves 

 crowded near the summit, frequently exceeding the inflorescence; 3-5 

 inches long, broadly ovate or ovate-lanceolate, the upper acute or sub- 

 acuminate, prominently serrulate, mostly abruptly rounded to the base, 

 drying dark: flowers erect, near the end of the stem: petals 2-3 lines long, 

 more or less purple ; capsules about 30 lines long, short-stalked ; seeds 

 coarsely hyaline-papillate or with the papillae often entirely collapsed, 

 very blunt above; coma dingy. Alaska and Brit. Columbia, perhaps 

 "Washington. 



E. breyistylum Barbey. Bot. Cal. i, 220. Slender pubescent, leaves 

 scarcely 2 inches long, ovate or elliptical, loosely and uniform.ly distrib- 

 uted along the stem, the uppermost reduced and surpassed by the nearly 

 glabrous capsule ; seeds slightly tapering upwards, coarsely hyaline-papil- 

 late. Springs etc , Washington to California. 



E. ursiuum S. R. Parish. A span to a foot high, slender: both 

 leaves and siems below pilose with rather remote and spreading long 

 white hairs; the infloresence minutely glandular-pubescent: leaves an 

 inch long or less, rather uniformly and in larger plants remotely distrib- 

 uted, ovate, broadly lanceolate, the upper subacute and serrate, the lower 

 blunter and finely denticulate or nearly entire, very abruptly rounded to 

 the sessile base, flowers few, erect or somewhat nodding; petals white or 

 lavender, 2-3 lines long: capsules ascending 15 lines long on very slender 

 peduncles of more than half their length, soon glabrous ; seeds often very 

 rough, short beaked: coma rather scant, white. San Bernardino county, 

 California to Washington. 



Var. subfalcatum Trel. I.e. 101. Lower but often branched below, almost 

 without decurrent lines, densely tomentose or pilose to the glandular 

 shorter inflorescence ; leaves narrower sometimes falcate, entire or remotelv 

 and inconspicuously denticulate, mostlyjobtuse, more cuneateat base, more 

 tomentose with inconspicuous lateral veins; capsule at first very short 

 stalked. California to Southern Oregon. 



E. Halleanum Hausskn. Monog Epilob. 261 Tall and slender, glan- 

 dular-puberulent throughout or soon glabrous below, leaves remote, mostly 

 ascending 10-15 lines long ovate to oblong-lanceolate, the lower obtuse, 

 decidedly undulate-serrulate, abruptly sessile or some of them clasping, 

 decurrent by the broad base: flowers and capsules ultimately rather 

 remote in. the upper axils; petals 2-3 lines long, pale to mostly rather 

 deep violet; capsule almost 2 inches long on slender peduncles of nearly 

 equal length, exceeding the subtending leaves : seeds sometimes smooth, 

 usually very finely papillate, fusiform, blunt at base, with gradually nar- 

 rowed pale apex and hyaline beak ; coma scarcely dingy. Vancouver Island 

 to Oregon. 



* Leaves rather small with less conspicuous lateral veins evidently 

 petioled; stems terete but sometimes pubescent in lines. Much- 

 branched small plants, with the rather spreading leaves therefore 

 mainlv attenuate. 



E. leptocarpnm Hausskn. I.e. 258. A span or less high, glabrous except 

 for some incurved pubescence on the stem : leaves less than 10 lines long 

 broadly lanceolate, sparingly low-toothed, tapering from near the middle 

 to the obtuse or subacute apex and winged petiole ; flowers abundant
