about 6-12’ high, growing in clumps at low elevations; leaves 
nearly equaling the peduncle; bulbs propagating by division, — 
nearly spherical, about 6” long; sepals very variable, but always 
with at least a short acuminate tip. This is the most common 
of all the far western onions, abounding throughout Utah, Nev., 
parts of Idaho to Wash. and Calif. Blooms in May. 
Var. cuspidatum Fernald is simply a form with short and 
abruptly acuminate sepals, it is hardly worthy of varietal rank. 
ASB8C3D. General outline of meshes decidedly irregular or 
wavy; leaves 2 or more; bracts 2 (rarely 3 in A. campanu- 
latum); ovary distinctly 6-crested; sepals entire, about 3”’ 
long, rather lax, (somewhat stiff in A. campanulatum), 
acute; bulb coats white; plants about 1° high, but some- 
times lower in A. campanulatum; flowers many; pedicels 
Slender and rather Ion g. 
A3B8C3DE. Stamens exserted. 
51. A. Sanbornii Wood Proc. Phil. Acad, 1868 171. Retic- 
ulations very minute and irregular; bracts 4; sepals ovate-lance- 
olate; capsule very thin. Yuba to Mariposa Co., California, in 
the mountains, 
A8B3C3D2E. Stamens not exserted; vertical walls of the 
meshes rery deeply crimped, the sinuosities being almost 
as deep as the width of the meshes, very many and con- 
Spicuous; bracts 2, ovate or rarely lanceolate, about 6-9’’ 
Jong, scarcely as long as the pedicels; sepals ovate to lan- 
ceolate, shortly acuminate, about 3’’ Jong, with prominent 
midvein; hulbs nearly spherical, about 6’’ long, propagat- 
ing by little ranners which are sometimes 4’ long and 
have bulblets at the ends; horizontal walls of the meshes 
generally barely sinuous or nearly straight, except toward 
the hase of the coats; leaves 2, rarely 3, about as fong as 
the peduncle, flat, narrow; pedicels widely spreading. 
52. A. campanulatum Wats. Proc. A. A. 14 231. Rather 
slender plants, 4-12’ high; peduneles single; flowers about lead
