and whitish flowers in terminal racemes or solitary. Perianth of 
6 distinct equal persistent segments with a transverse margined 
nectariferous fold above the base. Stamens 6, inserted at the base 
of the segments: filaments subulate-filiform: anthers versatile, 
oblong, rounded at the apex, deeply perforated at the emarginate 
base for the insertion of the filament, dehiscent along each margin. 
Ovary triangular, 3-celled, the ovules numerous, in two rows in 
each cell, horizontal, anatropous. Style persistent, with shortly 
3-lobed stigma. Capsule chartaceous, loculicidally 3-valved at 
the apex. Seeds flat, with a brown membranously margined 
testa and very small embryo.

ing, 2-5 inches high: radical leaves filiform, equalling or exceeding the 
stem, triangular to teretish, the cauline ones short and diminishing up- 
ward, linear-lanceolate, somewhat sheathing: flowers erect, usually solita- 
ry: segments of the perianth oblanceolate, obtuse, obscurely pitted at 
base, 4-5 lines long, white with 3 purplish lines: capsule obovate, obtusely 
angled, 4 lines long. Eastern Oregon to the Rocky Mountains and the

11 ERYTHRONIUM L, Sp. 305. 
Low herbs from membranous-coated corms with 2-3 apparent- 
ly radical flat leaves and one to several large flowers in a terminal 
raceme. Perianth broadly funnelform, of ¢ distinct nearly equal 
lanceolate deciduous segments that are mostly revolute from 
near the base, the inner usually auriculate below and callous- 
toothed on each side of a nectariferous groove. Stamens 6, hy- 
pogynous, with rather short slender filaments and linear anthers 
attached by the base and longitudinally dehiscent. Ovary nearly 
sessile, many-ovuled. Style slender, entire with short 3-lobe stig- 
ma, or 3-cleft and the stigmas at length revolute, deciduous. 
Caqsule membranaceous, obtusely triangular, loculicidally 3-val- 
ved. Seeds in two rows in each cell, ascending, with brown or 
black rugulose testa somewhat loose at the apex. 
E. grandiflorum Pursh Fl. 231. Scape stout, 1-2 feet high: leaves 
broadly lanceolate, 4-6 inches long, acute and shortly cuspidate, pale 
reen, not mottled: segments of the perianth bright yellow with whitish 
ase; outer ones lanceolate, obtuse; inner ones narrower, acuminate, with 
4 stout hyaline teeth at base, all strongly revolute; 144-3 inches long: style 
clavate ; the stigmas at length distinct and recurved. In the mountains of 
eastern Oregon to Brit. Columbia and the Rocky Mountains. 
Var. parviflorum Watson Proc. Am. Acad. xxvi, 129. Scape usu- 
ally 8-12 inches high: leaves oblong-lanceolate; flowers smaller, the seg- 
ments 12-15 lines long. In the mountains California to Brit. Columbia 
and the Rocky Mountains. 
E. revolutum Smith in Rees’ Cyc. Scape 10-12 inches high, 1-3- 
flowered: leaves narrowed below to a usually narrow petiole, 2-6 inches 
long, conspicuously marked with dark brown and white: segments of the
