E. Hammondi. Stems slender and flexuous,l-3 feet high, paniculately 

 branched above, glabrate and whitish below : leaves linear, 1-2 inches long : 

 flowers larger, borne towards the ends of the branches, erect: calyx tube 

 6-8 lines long, almost filiform below ; petals obcordate, 6 lines long or more, 

 bright purple : capsule lanceolate to somewhat clavate about an inch long, 

 ascending. On dry rocky slopes, Southwestern Oregon, blooming in 

 August and September. 



E. minutum Lindl. Hook. Fl. I. 207. Stems slender, a span or two 

 high, simple or mostly with ascending branches throughout, crisp-pubes- 

 cent below: leaves 6-10 lines long, usually alternate, narrowly to broadly 

 lanceolate or the lowest spatulate, acutish, undulate, cuneately narrowed to 

 a slender winged petiole; flowers rather numerous, erect; calyx tube 

 broadly funnel-form, short; petals 1-2 lines long; capsules about one inch 

 long, narrowed to the base, on short pedicles; seeds less than a line long, 

 reticulated or low papillate. Brit Columbia to California. 



* * * Stigma clavate, entire or slightly notched: coma of seeds 

 mostly persistent. Plants of various habit; perennial by rhizomes, 

 stolons, turions, etc. (Exceptions are E. exaltatum and E. Oreganum, 

 both of which have conspicuously 4-lobed stigmas.) 



-t- Spreading by filiform remotely scaly subterranean shoots which 

 end in ovoid winter bulblets with fleshy scales: capsule many-seeded: 

 seeds more or less papillate mostly fusiform with conspicuous trans- 

 lucent beak at insertion of coma. 



E. palustre L Sp. 348. Quite canescent above, with incurved hairs; 

 leaves 1-2 inches long, narrowly oblong or rarely lanceolate, obtuse or 

 almost truncate, gradually narrowed to a sessile base : fruiting peduncle 

 often long and slender; flowers few, mostly nodding: at first; seed fusiform 

 with prominent scarcely narrowed translucent point. Swamps and wet 

 places, Alaska to Oregon and the N. E. states. 



-«- -i- Producing at base of stem in late summer and autumn ro- 

 settes of foliage; leaves not re volute, more or less toothed: seeds 

 papillate. 



-M- Habit of E. palustre : stems terete or with occasional low decur- 

 rent lines : seeds fusiform, prominently beaked. 



E. JJavuricum Fischer. A span or two high, mostly simple, the very 

 slender stems sparingly incurved-pubescent, otherwise glabrous; roots 

 densely fascicled : leaves less than 8 lines long, somewhat crowded at base, 

 alternate and remote above, linear or oblong, obtuse, remotely denticu- 

 late, sessile, 1-nerved : flowers pale, not very numerous, nodding: capsule 

 erect, 20 lines long, on long slender peduncles ; seeds less than a line long ; 

 coma white. Bogs Alaska to Washington and east to the Selkirk range.
