glabrous above, villous below like the petioles, but less so, the 

 margins ciliate: peduncles purplish, commonly equalling the 

 leaves when mature, villous: racemes 6 cm. long or less: flowers 

 not verticillate, rather dense, of a rich deep violet-purple, 1 cm. 

 long and as deep, 7 mm. between apices of banner and wings: 

 bracts 3 mm. long, subulate, purplish at first, fading brown, 

 bearded with stiffish hairs: pedicels 2 mm. long, pubescent: 

 calyx tube glabrous, bright green as are both lobes at blossom- 

 ing time, but the upper turning paler with age, 2 mm. or a little 

 more in length, 2-parted, ciliate on the edges, the body glabrous; 

 lower lobe 5 or 6 mm. long, 2-toothed, the teeth 1 mm. long, a 

 tuft of hairs in the sinus, pubescent externally as well as ciliate 

 on the edges: banner marked on the face with a quadrate spot 

 of bright yellow 2 mm. across, this fading brownish in age, apex 

 notched, 3111111. wide, sides reflexed but the edges not parallel, 

 the space across the flaring base 6 mm. wide; wings much in- 

 flated, the edges 4 mm. apart at base, exposing the keel to a lit- 

 tle above the point of curvature, the blade rhombic-obovate 

 when spread out, 7 mm. long, 4 mm. wide; keel glabrous, some- 

 what bow shaped dorsally, but little curved ventrally: pods 

 ovate, 1 2mm. long, 7 or 8 mm. wide, pubescent", but not densely

The type, deposited in the herbarium of the Nevada Agri- 

 cultural Experiment Station, is my no. 9669, collected May 17, 

 1909, at Rhyolite, Nye county, Nevada, along the northern base 

 of Ladd mountain, growing in sand, the elevation 3575 feet. It 

 is plentiful at a point just beyond the Touopah & Tidewater 

 station, and extends northward across the level space to and be- 

 yond the tracks of the Las Vegas & Touopah Railroad. 



In habit it is much like L. brevicaulis and L. Sliocklryi, but 

 as may be seen from the descriptions and key, differs consider- 

 ably from both. The deep violet-purple corollas, marked on the 

 banner with a quadrate yellow spot, reminds one of the flower ^i 

 L. odoratus^ but in nothing else, for outside of color none oi the 

 characters are identical.
