petal-like ones obovate-oblong, widely spreading, cucullate, barely- 

 acute, 2 lines long, ascending, white; keel truncate, i^ lines long, 

 I line wide, broadly obovate, greenish; banner oblong-linear, ex- 

 panded at end and rhomboidal, erose and notched, greenish, tip 

 purple with veins running down Yq, line, 2 lines long in all. The keel 

 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, 2^ lines long and ij^ wide, deeply notched. The 

 plant is a shrub i 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. 



W Viola Beckwithii 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 of 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 L. 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 i to 2 feet high, in 

 clumps from a hard woody root, on gravelly slopes, flowering in 

 June. I have a very few specimens with a suspicion of blue on the 

 banner.

 note (No. 2) this includes P. mephitica Watson. A careful compari-
