26. A. BiceLovu, Watson. Bulb-coats very dark; reticulation 
distinct, of nearly regular vertically oblong cells: scape 3 to 6 inches 
high: flowers rather few, on stout pedicels 4 to 8 lines long, tinged 
with deep rose-color; segments oblong-lanceolate, acute, 4 to 6 lines 
long: filaments all with a rather narrowly deltoid base: crests con- 
spicuous. — King’s Rep. 5. 487, t. 38, f. 8, 9. Arizona (n. 532, 
Palmer) and New Mexico. 
27. A. Lacunosum. Bulb-coats light-colored, thick and distinctly 
pitted by the quadrate or transversely oblong reticulation, the outlines 
very minutely sinuous: scape 3 to 6 inches high: flowers usually few 
(5 to 20), on pedicels 3 to 5 lines long; segments 3 or 4 lines long, 
oblong-lanceolate, acuminate, a little longer than the filaments, which 
are all narrowly deltoid at base: cells of the ovary with an obtuse 
thickened ridge toward the top on each side. — Coast Ranges (Santa 
Clara County, on Mariposa Peak; n. 1284, Brewer). 
28. A. Nevu. Bulb-coats white or reddish, thin, with compressed 
transversely oblong reticulation (as in A. tribracteatum), the cell- 
outline not at all sinuous: scape slender, 6 or 8 inches high: pedicels 
rather few, slender, 4 to 6 lines long: perianth-segments light rose- 
color, lanceolate, acuminate, 3 lines long, scarcely exceeding the sta- 
mens and style: cells of the ovary with a thick short crest on each 
side near the summit. — Oregon (Hood River; Rey. R. D. Nevius). 
= = Filaments filiform above the obscurely and obtusely lobed disk. 
29. A. CAMPANULATUM. Bulb-coats not known: scape 4 to 6 
inches high: umbel somewhat nodding, many-flowered, the slender 
pedicels 4 to-15 lines long: flowers somewhat campanulate, the 
segments broadly ovate-lanceolate, acute or abruptly and_ shortly 
acuminate, 4 lines long, a third longer than the very slender stamens 
and style: capsule prominently crested. — Sierra Nevada (Mariposa 
to Plumas Counties; n. 4943, Bolander; Mrs. M. E. P. Ames). 
30. A. Bipwetiiz. Reticulation of bulb-coats not known: scape 
2 or 3 inches high: umbel rather few-flowered, the pedicels a half- 
inch long: perianth-segments narrowly lanceolate, acuminate, 2} or 3 
lines long, scarcely exceeding the stamens and style: crests con- 
spicuous. — Sierra Nevada (above Chico, Mrs. J. Bidwell, May, 1878). 
* * * Bulb-coats not fibrous: leaf solitary, narrowly linear or filiform, equal- 
ling or somewhat exceeding the low scape (2 to 5 inches): capsule promi- 
nently 6-crested: stamens and style included. 
+ Stigma 8-cleft with linear lobes: leaf revolute-filiform: scape very slender. 
31, A. Parry. Bulb-coats reddish-brown, without reticulation 
scape 3 to 6 inches high: spathe-valves 2 or 3, abruptly setaceous-
