A. obtusum Lem., but if that species is correctly described, this 
differs in having 2 bracts instead of 3, erestless capsules, and has 
regularly not the slightest resemblance to A. Nevadense or A- 
tribracteatum. 
36. A. minimum p.sp. The most delicate of all the onions; 
lzaves and peduncles almost filiform, the former 3-4’ long, the 
latter rising barely above the ground; leaves 2; bracts ovate, 
acute, 3” long, 2; pedicels barely 2” long; flowers less than 10, 
broadly bell-shaped, 2” long, red tipped, white and hyaline and 
green-nerved below, sepals ovate, broad, barely acute; filaments 
flattened but not much larger below, half as long as the sepals; 
ovary depressed-globose; bulbs small, about 4” long, ovate to 
oval, normally with a thick, red inner coat which is prominently 
marked, rarely white throughout, the other coats very thin and 
membranous, in all about 5, markings nearly rectangular with 
rather irregular sides, from square to broadly oblong. Alpine 
summits of Cuddy mountains, Idaho, July 2, 1899. 
37. A. Simillimum Henderson Torr. Bull. 27 355. Scapes 
1-13’ long, slender, flat and narrowly winged; bulb ovate, 4-6” 
long, loosely covered with the membranous coats; reticulations 
long-rectangular above, then square, then wider than long 
and meshes 5-7-sided; leaves 2, about $° wide, 3-4’ long, falcate 
to recurved; bracts 2, broadly ovate; acute to acutish; flowers 
6-9, 23-3” long, on slender pedicels 1-14” long; sepals narrowly 
oblong, obtuse, delicately denticulate below with spreading 
papilla, purplish-white, with sirong and green midnerve; 
stamens }-2 the sepals, filaments widened below and attached 4 
the way up; anthers oblong-oval; ovary slightly crested. Secesh 
Peak, near Payette Lake, Idaho, July 2, 1895, This is near to 
A. minimum but differs in the flattened and winged scape, slender 
pedicels, crested ovary, and papillate-ciliate and narrow sepals. 
It has the same habit. 
A8B2C2DE2F2G. Capsule distinctly crested. 
38. A, obtusum Lemmon Pitt 2 69. Seapes 2-3’ high, slen- 
der; whole plant rose,colored; leaf 2-3” broad, usually faleate;
