purple; sepals from rarely to conspicuously acuminate, spread- 
ing, midrib dark; ovary globular, with prominent central crests; 
leaves very narrow (except in very young plants) and probably 
longer than the peduncle; bulb coats brownish, never pure 
white, crimpings of the vertical walis of the meshes very deep 
and not conspicuously different on the upper end of the coats; 
ribs about 8; bulblets often purple. This grows in the high 
Sierras of California in Nevada and Plumas Cos. This is what 
the writer takes to be the true A, campanulatum. 
53. A, bisceptrum Wats. King’s Rep. 5351. Plants rarely 
less than 1° high, normally about 14° high, quite succulent; 
leaves broad when fresh, often 3” wide, taper-pointed; stems 
often 2 to each bulb; bracts very broadly ovate and very delicate}. 
flowers white to light-pink; sepals without prominent midveins 
scarcely at all acuminate, mostly broadly lanceolate, little 
Spreading; crests on the angles, prominent; bulb coats white or 
nearly so, about 12-ribbed, rarely. pink or some of the outer 
coats brownish, meshes very minutely sinuous, less coarse and 
much shorter than in A. campanulatum, but very variable, as 
they approach the top of the coat they become more uniform 
until they are regularly, varrowly, and vertically oblong and 
with rectangular angles and with walls simply beaded, these 
latter meshes vary from quite wide to very narrow. The Ne- 
vada forms which represent the type of the species have dark 
flowers even with a tinge of lead-color, the leaves are normally 
2” wide though wider ones occur, but both forms exist in Utah. 
This onion abounds in the shade, on moist slopes, in the Oak Belt, . 
and is found throughout central and northern Utah and Nevada 
to the Sierras. This hardly differs specifically from A. Palmeri. 
It blooms in June. 
2A. Ribs (not over 11) of the many bulb coats short, branched 
throughout and united into coarse, diamond-shaped, regu- 
lar and very large meshes; bulb coats soon breaking up 
into coarse, thread-like ribs at the top, losing the membra- 
nous covering, and becoming a mass of interlaced fibres;
