LTJPINUS RUBRICAULIS. Perennial, the tufted stems slen- 

 der, a foot high or more, simple, remotely leafy with rather 

 small very slender-petioled leaves, both stem, petioles and, 

 in part the leaves dark red-purple and sparingly and min- 

 utely silky-villous : leaflets about 7 or 8, cuneate-oblong or 

 elliptical, unequal, the largest 1J inches long, the slender 

 petioles much longer; stipules small, subulate: raceme ses- 

 sile, 3 or 4 inches long, rather dense, the flowers scattered, 

 middle-sized, pedicels and very gibbous calyx white-silky; 

 corolla dark blue-purple, banner shortest of all the petals, 

 the narrowly pointed falcate keel longest and naked: fruit 

 not seen. 



On moist slopes of Crested Butte, 6 July, n. 342; con- 

 spicuous by the dark purplish hue of the herbage, and in 

 habit quite an elegant species. 



LUPINUS ARCEUTHINUS. Stems rather rigidly erect, form-

 leaflets 7 or 8, lance-elliptical, acute, the largest 2 inches 

 long; raceme sessile, 6 inches long, rather dense, all the 

 flowers scattered, rather large; stout pedicels, and short gib- 

 bous calyx scarcely more velvety than the rachis; corolla 

 wholly dark blue-purple, the petals subequal, the not 

 strongly falcate keel densely woolly-ciliate throughout : 

 pods more than an inch long, quite broad, velvety-tomen- 

 tose. 



At Cedar Edge, 24 June, n. 246. 



LUPINUS DICHROUS. Size and habit of the last, with
