petal- like ones obovate-oblong, widely spreading, cucullate, barely 
acute, 2 lines long, ascending, white; keel truncate, 114 lines long, 
t line wide, broadly obovate, greenish; banner oblong-linear, ex- 
panded at end and rhomboidal, erose and notched, greenish, tip . 
purple with veins running down ¥% line, 2 lines long in all. The kee} 
has an oblong orifice with the lips turned back at more than a right 
angle; stigma truncate or club shaped and included in the hood; pod 
oblong ovate, 21% lines long and 1% wide, deeply notched. The 
plant is a shrub 1 to 3 feet high, with gray bark and stems often an 
inch thick, widely and rather intricately branched and spiny. Grav- 
elly hillsides in dry places. I have collected it at Lee’s Ferry on the 
Colorado River near Southeast Utah, and found it common in West- 
ern Utah and Eastern Nevada. 
VioLa Beckwitutl Torr. The description of this plant in King’ s 
Rep. is inaccurate, but the figure, etc., in Beckwith’s Rep. are bet- 
ter. The following are the characters os our plant as it grows here; 
it is locally abundant. Stigma cuneate and truncate, glabrous, petals 
also glabrous, 2 upper ones dark purple, the rest white with a yellow 
claw and purple veined, lower petals broad, truncate or emarginate, 
flowers rather large; sepals linear oblong, spur not over a line long; 
pubescence minute and dense; leaves 3-divided, divisions petiolulate, 
lateral ones 3 to 6 lines long, terminal ones 6 to 12 lines long, lobed 
or cleft into many linear or oblong segments. 
LUPINUS SULPHUREUS Douglas. This little known plant I dis- 
covered growing abundantly in Eastern Nevada, and I think it is 
quite probable that it will be found to be nearer Z. sericeus than has 
been supposed. My notes on the flowers were taken as they grew. 
When the flowers are just opening they are white with a yellow streak 
in the middle of the banner, which is also flecked with 4 or 5 small 
purple spots; the whole flower soon turns yellow, the middle of the 
banner deeply so. The calyx is long-spurred, spur and all but the 
tip of the upper part of the calyx white and streaked with blue, the 
lower part of the calyx and tips green. It grows 1 to 2 feet high, in 
clumps from a hard woody root, on gravelly slopes, flowering in 
une. I have a very few specimens with a suspicion of blue on the 
banner. 
PSORALEA CASTOREA Watson. As I suggested in a previous 
note (No. 2) this includes P. mephitica Watson. A careful compari-
