Var. PARVirLORUM. Scape usually low ; fluvvors smaller, the se^- 

 meuts 12 to 15 lines long. — E. Natlalliunum, Kej,a'l, Gartenil. t. G'J5, 

 not R. & S. ; E. grundlflorum, Murray, Gard. Cliron. 1874, fig. 173. 

 lu the mountains from Colorado and northern Utah to British Amer- 

 ica, in the Blue Mountains of Oregon, and in the Cascade Mountains 

 of Washington and British Columbia ; the more common form. 



The var. Murrayi of Morreu (Belg. Hort. 26. 105, t. G) is a doubt- 

 ful cultivated form similar to this, but said to have mottled leaves. In 

 a single specimen collected by IVIr. Henderson above the timber-line 

 on the Olympic Mountains, Washington, the leaves are evidently 

 mottled. 



++ ++ Leaves more or less mottled. Pacific Coast species. 

 = Corms producing slender offshoots from the base. 



6. E. Hartwegi, Watson. Corms small (6 to 8 lines lono-') : 

 leaves (rarely 3) often alternate: flowers 1 to 3, pale yellow with an 

 orange base, the segments 1 to 2 inches long by 3 to 6 lines broad or 

 more, spreading or scarcely recurved : capsule unknown. — Proc. Am. 

 Acad. 14. 271. In the Sierra Nevada, California, from Mariposa to 

 Plumas Counties. This species, or a similar one, is also reported 

 from near Healdsburg, Sonoma County (^R. H. Thompson). 



= = Corms (1 to 2 inches long) produced in succession upon a usually short 



rhizome. 



7. E. REVOLUTUM, Smith. Leaves attenuate to a usually narrow 

 petiole : scape often over a foot high, 1-2-flowered : perianth " white" 

 to pale yellow, yellow at base, the segments narrowly lanceolate (3 or 

 4 lines broad) : capsule abruptly acutish at the apex, 12 to 15 lines 

 long. — Eees' Cyc. E. grandijlorurn, var. Smithii, Hook. E. gran- 

 dijiorinn, var. revolutum, Baker. Vancouver Island to the lower 

 Columbia valley. Described by Smith as having purplish flowers, and 

 an original specimen in Herb. Kew bears the note " fl. rubr. purp." by 

 Sir W. J. Hooker, but it is rarely that the petals assume a pinkish 

 tinge in drying, and the ground for the statement is unknown. No 

 purple-flowered species is now found on Vancouver's Island, where 

 Menzies's specimens were collected. 



Var. BoLANDERi. Usually low, 1-3- (rarely 4-) flowered ; perianth 

 white with yellowish centre, becoming rose-purple ; appendages very 

 prominent. — In the redwoods of Colusa, Mendocino, and Trinity 

 Counties, California. 



8. E. GiGANTEUM, Lindl. Leaves narrowed to a usually short 

 and broadly margined petiole : scape often tall, 1-6-flowered or more : 

 perianth cream-color (often described as white) with a light yellow or
