. A. macrum Wats. Proc. A. A. 14 233. Leaves 2, dis- 
tinctly Sonertin peduncles 1-4? high; bracts 2, acute; slender 
pedicels 2-3” long; sepals white or purplish, 2-3” long, narrowly 
lanceolate-acuminate, scarcely exceeding the stamens; cells of 
the ovary with thick, obtuse crests at the summit. This plant 
cannot be separated from A. madidum except by markings of 
scales. Probably is the same as A. Nevii Watson. Union Co., 
Oregon, on rocky hills, Cusick. 
A8B2C2D. Reticulations evident, walls of reticulations not 
minutely sinuous, except in A. attenuifolium to A. Bolan- 
deri probably, in which some of the horizontal lines have 
a few waves; peduncles slender, filaments deltoid-dilated 
at base; bulbs propagating by division. 
A8B2C2DE. Reticulations transversely oblong to linear; 
Straight or nearly so: peduncles a few inches high; leaves 
longer than the peduncle. 
A3SB2C2DEF. Leaves 2, rarely 1 in A. tribracteatum; bulb 
coats mostly red, rarely white, thin, ends of reticulations 
pointed; pedicels slender; crests not large; sopals about 3’’ 
long, acute, longer than the stamens. 
32. A. Nevii Wats. Proc. A. A. 14 231. Peduncles 6-8’ 
high, pedicels rather few, 4-6” long; sepals white to rose-colored, 
lanceolate-acuminate, a little longer than the stamens; cells of 
the ovary with a thick, short crest on each side near the top; 
bracts 2. Hood river, Ore., also the southern Blue Mts., Cusick, 
No. 1642. Blooms in May. This is probably a synonym of A. 
madidum. 
33. A. tribracteatum Torr. Pac.R. R.4 148. Leaves some- 
times 1, in the type greatly exceeding the very stout peduncle; 
capsule obscurely, if at all, crested; leaves 3” broad or less, flat 
and grass like; peduncles 1-2’ high; bracts 3, long-acuminate; 
pedicels 2-3” long; sepals with dark midvein, narrowly oblong- 
lanceolate, acutish, little longer than the stamens. Alpine in
