tatum just before A. ambiguum so that A. Nevii and tribractea- 
tum could come next to A. Brandegei to which species they are 
most related. The transverse markings of this whole group 
from anceps to tribracteatum are very much alike, being from 
narrowly oblong to linear, straight and acuminate at both ends, 
the sides uniform and without waves, meshes ae a magnifica- 
tion of 40 diameters 3-4” long and not over 1” w 
On page 11 A. campanulatum and A. Bidwellise are men- 
tioned because they were originally described without bulbs. 
The former is almost certainly correctly placed on page 26 as a 
too close congener of A. bisceptrum into which it seems to pass 
at lower elevations in Nevada. A. Bidwelliz is still an enigma 
unless it is aform of A.hyalinum as some suppose. A. scilloides 
and A. collinum are also mentioned on page 14 as unknown 
quantities though the place of the latter is probably on page 23. 
A. Bolanderi should come after A. peninsulare. To the key 
in this group the last line should be “narrowly oblong’ to linear 
“in general outline.” On page 17 under A3B2C2D change “to” 
to “and” in second line, and omit “probably” in the next line. 
On this same page A. macrum should be put where A. 
Nevii is and the latter should be placed under it as a synonym, 
as they are clearly identical, this has been determined from 
authentic material recently received. The last word under 
Nevii should be “‘macrum” and not ‘‘madidum.” 
n page 4, second line from the bottom, insert “into equal 
parts” after “branch.” 
A. Nevadevse Watson. This little known species, when 
fresh, is characterized as follows: Leafround, channeled on the 
upper side; bracts reddish-green; pedicels stout, 6” long, ascend- 
ing; flowers white; sepals with the outer 3 reddish-brown to the 
base, the inner 3 only at tip and a trifle narrower, pot keeled, 
spreading at an angle of 45°, equal, 3” long , oblong-ovate, acute 
but not acuminate, midrib greenish within; stamens 2” long; 
filaments subulate; anthers oval-oblong, 4” long; style 14” long;
